Your oil may keep your pistons slick enough to prevent them from generating friction — but your coolant does the rest of the work to keep everything at a workable temperature. This is especially important for whenever you’re hauling large loads that require a lot more torque, especially when you want to combine that hauling power with acceleration!
In a nutshell, you just got the engine you’ve always wanted. Don’t lose it to something as simple and affordable as coolant! So, without further ado . . .
Here are our recommendations for the 4 best 6.0 Powerstroke coolants on the market:
Royal Purple Purple Ice Super Coolant
Royal Purple ROY01600 Purple Ice super coolant is a multi-function cooling solution that simplifies the engine maintenance process while maintaining outstanding performance.
This coolant is designed to reduce surface tension throughout your engine while allowing more heat to transfer outside of your radiator. That means you get the same outstanding performance from your Powerstroke without having to worry about it overheating!
On top of that, this coolant reduces engine hotspots for a more consistent temperature under the hood. It even inhibits corrosion and protects the aluminum parts of your engine long-term. Best of all, it’s safe to use in a water and / or anti-freeze blend.
If you want an affordable and convenient coolant for your engine, the Royal Purple ROY01600 is one of the best 6.0 Powerstroke coolants around!
Zerex G-05 Anti-freeze / Coolant
The Zerex G-05 anti-freeze / coolant combination is a catch-all solution to both gasoline and diesel engines. With its special-crafted formula, this anti-freeze / coolant combo coats and protects all engine metals from corrosion — including aluminum!
Beyond that, this coolant contains nitrites that help protect the liners of your engine cylinders, improving their durability and lifespan. The cooling formula also contains an additive to protect against scale and other hard water deposits that come from getting every ounce of power out of a high-octane engine. Best of all, this coolant is safe to use in hoses or store in plastics because it has a quality defoamer system that prevents it from harming other materials — even vehicle finishes!
Overall, the Zerex G-05 anti-freeze / coolant is a ready-made solution to keeping your Powerstroke engine in ideal condition. In terms of purpose, this formula does just about everything under the sun (and then some)!
Genuine Ford Coolant VC-7-B Gold Concentrated Anti-freeze
The Genuine Ford Fluid VC-7-B gold coolant is the easiest and safest way to keep your Powerstroke working like a charm.
This coolant is specially formulated for Ford engines, gasoline or diesel. It provides year-round antifreeze and antiboil protection, and it even gives your engine extra protection against corrosion. Diluting this coolant with water (50/50 mix) reduces the protection to -34 degrees Fahrenheit and 265 degrees Fahrenheit for antifreeze and antiboil, respectively.
As a final warning, we have to warn against mixing different colors or types of coolant in your engine. There’s no telling how they could react. With this coolant in your Ford Powerstroke engine, you’re keeping your engine safe from the hardcore wear and tear that affects so many other diesel engines.
It may be a bit pricier than other coolants, but the peace of mind (and a working truck) are worth the cost! This is surely one of the best 6.0 Powerstroke coolants for the money.
EVANS Cooling Systems Waterless Engine Coolant with Funnel.
The EVANS Cooling Systems EC53001 high performance engine coolant is specifically designed for the 6.0 Powerstroke engines that get pushed to their limits on a regular basis.
It excels in all gasoline-powered engines, and it’s ideal for light-duty diesels that you can find in industrial applications. With a boiling point of 375 degrees Fahrenheit, it’s easy to understand how this coolant can help you get every last drop of performance out of your engine.
This coolant is made without any water, and it’s formulated not to vaporize, boil over, and after-boil. It creates low pressures, and it actually reduces strain on an engine’s cooling system as a whole. Plus, because of how it’s made, there’s virtually no risk of corrosion on any engine parts. All of this comes together to ensure that this coolant prevents engine knock and pre-ignition knock so that your Powerstroke generates a smooth, consistent ride every time you use it.
As a special note, keep in mind that this coolant is not compatible with any others. In fact, if you’re going to use it, you MUST fully drain your engine of any other coolant before adding the EVANS EC53001.
So Which Is the Best Engine Coolant for 6.0 Powerstrokes?
One of the big differences in our list is quantity. If you only need to top off your engine with a safe and reliable coolant, go with Royal Purple. It’ll deliver an excellent product that’ll keep your Powerstroke going strong. Will it be enough to fully cool your engine with one bottle? Probably not. But it’s enough to keep you going without dropping a lot of money in one place.
What about combination coolants? We have two anti-freeze / coolant combos on this list that’ll work for you just fine, if you don’t want to bother with separate formulas. This’ll help you cut down on costs of buying specialist coolant and anti-freeze separately, which simplifies engine maintenance for any Powerstroke owner.
You can always go big on the special and specific coolant formula that’ll keep your Powerstroke going hard at all times. The EVANS formula (see full specs) is a great opportunity to eliminate any of the kicks or bucks you might feel pre-ignition and during internal combustion. This coolant also has one of the highest boiling points available, and its waterless formula basically guarantees it won’t corrode your engine block. All in all, this is the best 6.0 Powerstroke coolant for anyone out there who’s looking purely at quality.
Finally, if you want a Powerstroke coolant that you’re sure will be kind to your engine, go with the Genuine Ford Fluid VC-7-B (see full specs). This stuff is the real deal when it comes to Ford diesel engines, and it’s the best option for the long-term health of your Powerstroke.
