Big, mighty engines like the PowerStroke are always at the risk of overheating. To prevent them from breaking down prematurely, you’ll need a decent-quality air filtration kit, exhaust system, and, of course, antifreeze. But wait – how is that coolant going to stay cool? That’s where radiators come in. The coolant is constantly flowing through the engine. Pushed by the water pump, it absorbs the heat generated by the motor.
Next, the liquid rushes back into the radiator, where it’s cooled down. So, the radiator needs to be efficient enough to handle all the heat. Today, we’ll focus on finding the best radiator for PowerStroke. I’d been testing dozens of units for a full month and now I can finally share my top picks with you! We’ll start with the 6.0-lit motor, and go from there!
Best Radiator for 6.0 Powerstroke Review
1. Mishimoto – MMRAD-F2D-03 Aluminum Radiator
An obvious leader among third-party radiator manufacturers, Mishimoto is famous for its premium-quality products. The MMRAD series has been around for quite some time now and is known for its strong, reliable performance. As for this particular rad, it will be a perfect fit both for light- and heavy-duty trucks. Durable, and highly efficient, it was specifically designed with the 6.0-lit PowerStroke in mind.
Add the company’s trademark lifetime warranty, and you’ll see why Mishimoto has such a strong foothold on the market. Full-aluminum construction, the two-row design, and drop-in installation are even more reasons to consider it over the competition. I do have to mention the (minor) issues with quality control, though. Some Ford drivers complain about dented packages, lack of installation hardware, and scratches.
Despite the problems with quality assurance and control, the F2D-03 aluminum radiator is a bargain. It fits the PowerStroke motor like a glove and will keep it nice and cool. Sturdy, smooth, and efficient, it will be a great upgrade both for a lightweight and a heavy-duty truck.
2. G-plus motor – High Performance 2 Row Core Aluminum Racing Radiator for 6.0L Powerstroke
Moving on with the list, we’ve got G-Plus – another fan-favored and critically-acclaimed brand. This radiator features a universal, highly flexible design that makes it compatible with a long list of vehicles. Another big selling point is the extended coolant capacity. It provides a 30% boost compared to the factory gear, which is quite a significant gain, especially if you do lots of off-roading and put both the engine and the cooling system through a tough test.
More importantly, G-Plus is available at a very attractive price. So, if you’re on a budget but still need to replace the restrictive stock radiator, this unit might be exactly what you need. Do keep in mind, however, that the cooler threads are a bit too big and might cause some hassle during the installation. It’s nothing some Teflon tape won’t fix, of course.
This is one of the cheapest radiators for the PowerStroke, and it delivers excellent performance all-around. It easily fits a long line-up of Ford trucks and boasts an impressive coolant capacity. The cooler threads are a bit of a “miss”, but that shouldn’t be much trouble.
3. Prime Cooling – 2 Row Aluminum Radiator for 6.0L V8 Turbo Diesel Powerstroke Engine
Next up, we have Prime Cooling with another two-row radiator for the PowerStroke. Designed, built, and tested with hauling trucks in mind, it will be an excellent choice for heavy-duty truckers involved in the “towing business”. Thanks to the premium engineering and material quality, Prime Cooling easily handles the most extreme situations on the road. I’m talking about great heat/pressure tolerance.
What I didn’t like about this unit was the installation process. For the most part, it’s simple and straightforward. It might take you an hour or two, but you won’t need any expensive tools to make it fit. Unfortunately, it is a bit taller and thinner than the factory rad. To compensate for that, I recommend using rubber (like a sealant or just pieces of rubber) to close the gaps and prevent air from soaking through.
Owners of heavy-duty trucks will like how Prime Cooling performs on challenging terrain. On top of that, it keeps the engine cool no matter how much cargo you’re hauling. As for the cons, you’ll probably have to use some rubber to make the radiator fit and work properly.
4. HHAUTOSTORE – 6.0L Full Aluminum Radiator
This radiator right here is a safe bet. It doesn’t really have any significant downsides except for the bad packaging. It’s not horrible, of course, but still not on par with the competition. Moving to the pros, we’ve got fast shipping, superb cooling efficiency, and quality engineering. The delivery times are, indeed, quite impressive, and shipment won’t cost you a penny. As for the efficiency boost, you can expect a 45% improvement compared to stock gear.
That makes OzCooling one of the most powerful aftermarket radiators on the market. Therefore, if you’re constantly pushing your PowerStroke to the limit and are a bit worried about overheating, that won’t be an issue with the Oz radiator. Oh, and this is a US-made product, by the way, manufactured using domestic materials. Tested on the challenging American roads, it has proven its worth in extreme situations.
What are you looking for in a third-party radiator? Is it fast, charge-free shipping? Or maybe you put cooling efficiency first? Well, you’ll get all of that with this product, and then some. While the packaging isn’t particularly great, this US-crafted radiator is still a bang for the buck.
5. ALLOYWORKS – 2 Row All Aluminum Radiator For Ford
And what does AlloyWorks have to offer to a Ford truck owner? Why should you pick it over the other radiators on the list? Well, precision engineering can be a big reason for that. It ensures strong, steady performance, maximum efficiency, and long service life. This rad was designed specifically for rough, tricky roads. And it doesn’t matter whether you’re driving an F250 or F550 – you’ll get premium cooling in any case.
AlloyWorks prides itself in always putting its products through a series of demanding tests to ensure quality. That’s why this radiator might deserve a spot on your list of must-haves. There is one downside, though: the transmission cooler fittings don’t always fit the mounting spots. What you can do is shorten them a bit and that will fix the issue right up.
Precision-engineered and heavily tested in the most demanding conditions, the AlloyWorks radiator will be a bargain for the entire F-Series of Ford trucks. If you’re looking for a reliable “workhorse” to keep the motor cool and prevent overheating, this could be it for you.
Best Ford 6.4 Powerstroke Radiator Replacement Review
Mishimoto MMRAD-F2D-08V2 Performance Aluminum Radiator
Ok, now that we’ve checked out the finest third-party radiators for the 6.0-lit PowerStroke, let’s see what the market has to offer for the 6.4-lit V8. As always, Mishimoto is a safe bet, and F2D-08V2 is one of the most durable and long-lasting options for the F-Series. Premium-quality engineering and materials allow it to stay on top of its game for many years. I’m talking about 100% brazed aluminum core and TIG welding.
The rubber mounting pegs also add to the radiator’s reliability and strong performance. There is one big downside, however, and it has to do with the price: it’s just a bit too steep for the average Ford driver. On the other hand, if you make a living off driving a heavy-duty truck and want to protect the motor from overheating, you might like what Mishimoto has in stores with this rad.
The biggest turn-off of this otherwise superb radiator is the price. Yes, this is an expensive product, but with it, you’ll get high-grade build/material quality, reliable performance, and a perfect fit for the 6.4-lit PowerStroke.
2. Prime Cooling – 3 Row Core Aluminum Radiator
If the Mishimoto radiator is way too expensive for your budget, but you still want premium cooling, take a close look at this product. Here, we’ve got a three-row radiator that’s almost as efficient but comes at a more affordable price. As you’ll learn further down this review, three rows/layers don’t automatically mean better performance. But, in the case of this rad, it’s a big pro.
The lightweight, large surface area does an excellent job of “freezing” the coolant while it’s flowing through the tubes. The included drain plug isn’t very good, though – you’ll be better off with an aftermarket replacement (that’ll cost you $5-10). On the bright side, Prime Cooling arrives in a protective box that keeps the radiator from harm’s way.
The extended surface area, three-layer tube construction, and lightweight design turn Prime Cooling into a must-have. Packed in a safe, protective package, it will arrive at your doorstep ready to rumble. The drain plug is of poor quality, however, and should be replaced.
3. CoolingSky – 4 Row All Aluminum Radiator for 6.4L Diesel Powerstroke
So, we’ve already checked out two- and even three-row radiators. But what about a four-row unit – how effective is it going to be? Well, this radiator is obviously efficient. But, what makes it stand out even more is its ability to withstand extreme conditions and deliver strong performance no matter how hot it is outside. Aviation-grade aluminum engineering and 100% TIG-welding make it a worthy investment for any Ford owner.
And let’s not forget about the high-density fins. They make the radiator extremely productive and efficient. One thing to keep in mind: CoolingSky isn’t one of those quick-to-deliver companies. So, you might have to wait for a while before this package arrives. But, that’s a small price to pay for the exceptional performance and the four-row design.
CoolingSky’s biggest selling point is the four-row design along with premium engineering and high-density fins. F-Series drivers looking for superb cooling for their 6.4-lit PowerStroke engines will be pleased by this radiator, especially in demanding situations.
Best Radiator for 6.7 Powerstroke Review
1. Mishimoto MMRAD-F2D-11 Primary Aluminum Radiator
What is it that you’re looking to get with a brand-new radiator? Most truckers will answer “better cooling”, and that’s exactly what you can expect from F2D-11. Mishimoto engineers did their best to maximize this radiator’s cooling efficiency. As a result, you’ll get up to 37% better performance compared to the stock gear. If you’ve been driving around with the 6.7-lit PowerStroke for a while, you know how important it is to keep this motor cool.
The top-notch efficiency is achieved by making the main body/core 10% thicker than most rivaling products. Add Mishimoto’s standard lifetime warranty, and you’ll get a great investment for any F-Series heavy-duty truck. Sadly, I have to also mention the durability issues with this radiator. Simply put, it has a rather short lifespan. Many drivers claim it gives up on you in two-three years, which is bad news.
The biggest problem with this otherwise outstanding radiator is durability. And while you can, of course, take advantage of the lifetime warranty, it doesn’t always cover a breakdown. On the bright side, this rad provides a 40% boost in efficiency and delivers all-around strong performance.
2. Mishimoto MMRAD-F2D-11S Secondary Aluminum Radiator
And here’s another pro-grade radiator by Mishimoto. Only this time around, it is highly durable and reliable. You will have to pay a steep price for the extra longevity and efficiency, as this is one of the most expensive aftermarket rads for the 6.7-lit PowerStroke. At the same time, it’s very easy to install manually. You won’t have to pay a mechanic to help with that. The process is simple and doesn’t take an eternity to complete.
The package, in turn, includes (fully removable) thermostat housings. They help the radiator keep the coolant temperature low and protect the motor from overheating. In fact, F2D-11S keeps the entire system nice and cool, dropping the temperature by 6-7 degrees Fahrenheit. I’m talking about the fuel, EGR, and transmission, among other things.
Is this the most affordable radiator on the list? Far from it! However, it still deserves your attention, as it’s very easy to install, delivers excellent performance, and keeps the antifreeze, fuel, and other essential components cool, extending the engine’s lifespan.
3. Ford 6.7l Powerstroke CSF OEM Replacement Primary Radiator
Last, but not least, let’s look at a replacement radiator by CSF. Crafted from high-grade components/materials, it can be trusted with keeping the engine cool. ISO-certified, it has passed dozens of challenging tests with flying colors. And, it is one of the least expensive options for the 6.7-lit PowerStroke. CSF is significantly cheaper than both Mishimoto products.
Sadly, the installation process can be a bit tricky. Even though the official specs claim this radiator is a “drop-in fit”, you might have some minor difficulties with it. Mostly, I’m talking about mounting holes that don’t fit the factory spots. But, this inconvenience is more than compensated by the warranty: the manufacturer backs it with a one-year guarantee that should give you some peace of mind.
While CSF might not be a very smooth, drop-in install, you should put it on the list nonetheless. ISO-certified, it is ready for extreme conditions, challenging terrain, and hot weather. Plus, it is covered by a 12-month warranty and comes at a very affordable price.
Best Aftermarket Radiator for Ford 7.3 Powerstroke Review
1. Mishimoto MMRAD-F2D-99 Aluminum Radiator for 7.3 Powerstroke
The F2D-99 replacement radiator isn’t much different from all the other Mishimoto rads on the list. It’s just as efficient, durable, and reliable. Oh, it’s also quite expensive, which is another thing that most Mishimoto products have in common. But, if you’re serious about protecting the 7.3-lit PowerStroke V8, this unit right here will be a reasonable purchase. Primarily, it’s gonna be a drop-in fitment.
You won’t have to spend hours trying to make it work (only 30-40 minutes). Next, the end tanks are TIG-welded and aid in the overall longevity and durability of the radiator. And let’s not forget about the cores. Thanks to the minimal-distortion and low-stress cores, this two-row rad is capable of keeping the engine temperature at comfortable levels no matter how much pressure is put on it.
Folks in the market for an easy-to-install, reliable, and trustworthy radiator will find a decent pick with F2D-99. While this rad isn’t particularly cheap, it does carry excellent value and will be a beneficial purchase in the long run.
2. Mishimoto MMRAD-F2D-95 Performance Aluminum Radiator for Ford
Wait, another Mishimoto? Why would you choose this one when the #1 radiator is a premium-quality product? There are several reasons, actually. First of all (and this is arguably the most important factor), F2D-95 is significantly cheaper. In fact, it’s almost three times cheaper than the “big brother”. So, yes, be very careful when ordering a new rad online and pay extra attention to the names.
Moving on, I want to mention the superb-quality aluminum construction. It does exactly what any heavy-duty driver wants it to do: keep the coolant flowing and the engine pushing the truck forward. Super-Duty vehicles are this radiator’s field of expertise. Sadly, packaging isn’t F2D-95’s strongest suit. Like some other Mishimoto radiators, this one arrives in a box that isn’t at all protective.
Although this Mishimoto radiator arrives in lackluster packaging, I would still recommend checking it out. F2D-95 is affordable, efficient, and will be a great match for any heavy-duty truck.
Mishimoto MMRAD-F2D-83 Performance Aluminum Radiator
This is the last Mishimoto radiator on the list, and it’s a very good deal. In many ways, it’s like the golden middle between the previous two units. This applies to the price, overall performance, and everything else. Now, it’s not the most efficient rad out there, and that’s something of a downside. But, it will still be an improvement compared to the stock gear, of course.
Besides, if you’re driving an older truck, Mishimoto will be a perfect fit. Plus, F2D-83 comes with two very important extras – a drain plug and a cap. The plug is highly valuable, as it helps filter all the harmful metal fragments from the liquid (the antifreeze). As for the cap, it ups the boiling point of the coolant, resulting in a more “combat-ready” system.
You can’t go wrong with F2D-83, as it doesn’t have any big cons. It is a reasonable pick if you drive an older heavy-duty vehicle. Add a magnetic drain plug, a radiator cap, and decent performance, and you’ll get a winner.
4. Blitech 3 Row Aluminum Radiator for 7.3L Powerstroke V8
Do you prefer three rows over two? Then let’s take a closer look at Blitech. Designed to “handle” the 7.3-lit PowerStroke, it features a lightweight, easy-to-fit, yet sturdy body. This is one of those “sure thing” aftermarket investments that you won’t regret later. The three rows of tubing do a very good job of cooling the antifreeze down. The body, in turn, is constructed of T-6061 aluminum.
Direct, bolt-on installation, high coolant capacity, and stable performance are a part of the deal as well, along with fast shipment within the United States. There is one downside to keep in mind, though: Blitech arrives in minimal packaging. That means you won’t get all the nuts, bolts, and clamps necessary for the installation. So, don’t throw away the factory hardware!
What will you get with this third-party radiator? A little bit of everything, actually. While it’s not a full package and might not have all the installation hardware, Blitech is lightweight, brick-strong, and features a three-row design.
5. CoolingSky 3 Row Radiator for 7.3 Diesel Powerstroke Engine
Alright, CoolingSky is the last stop for today. And, it’s got a couple of perks up its sleeve. The company has a direct-line sale system that helps them provide premium-quality production. ANd, this radiator features a unique tubing design that makes it 30-40% more efficient than any PowerStroke factory cooling system. On top of that, it boasts advanced anti-corrosion protection, which ensures a long lifespan.
What I didn’t like about CoolingSky was the poor quality control. Missing installation hardware, slow delivery times, and wrong parts – that’s what you can expect. But, this only happens to a “select few” buyers, so it’s not that big of a deal. All things considered, this rad is still a crowd-pleaser.
CoolingSky is incredibly efficient and rocks a unique, aviation-aluminum body that’s on par with the most expensive rivals. It does have some QA issues, that’s true, but easy fitment and anti-rust protection make it a bargain.
Alright, that pretty much sums up my breakdown of the best PowerStroke radiators. We checked out 16 premium-quality radiators for four different PowerStroke engines – 6.0, 6.4, 6.7, and 7.3-lit. They all went through a series of rough tests and have proven their efficiency in real-world situations. With that said, there are still some (minor) cons along with the pros. And, of course, every single unit is unique.
So, I want you to read all the reviews carefully and pay extra attention to the advantages and disadvantages. That should help make the right choice.
