Oil Cooler for 6.0 Powerstroke – Buyer’s Guide

You have to know when it’s time for 6.0 Powerstroke oil cooler upgrade to avoid any potential damage to the engine. Here’s everything you should know:

What is an Oil Cooler?

Oil coolers are a kind of radiator whose job is to cool down the engine oil. These are typically located in the front or near the engine’s cooling system. This is different from the radiator in your vehicle that’s filled with a coolant.

The purpose of the cooler is to reduce the engine heat. When the oil flows inside the engine, it absorbs the heat and the oil cooler, in turn, absorbs that heat to cool it down.

The ideal temperature range of engine oil is 180 to 220 degrees. If it’s below or above this range, it may not perform efficiently and may even get consumed faster.

Oil coolers help increase the life of both the engine and the oil itself. The only drawback is that you may have to add more oil in the vehicle as some of it will fill the oil cooler as well, in addition to the engine.

Fun Fact about Oil Coolers: Not all vehicles have oil coolers, but these are pretty common in diesel cars or trucks, especially those that are used for towing.

How Do I Know If My 6.0 Cooler is Bad?

Are you short on time or just want a quick answer?

  5. PPE Heavy-Duty Oil Cooler Kit

It’s not so easy to know if your oil cooler has gone bad, as there aren’t that many apparent signs until it gets really bad (completely clogged). But as a rule of thumb, it might make sense to regularly check the oil cooler for a high mileage car. Over the years, it can get clogged, allowing very little coolant in and effectively impacting the performance of the oil cooler.

The best way to tell if your external oil cooler needs to be replaced is to measure the oil and coolant temperature at cruising speeds (40 to 60 mph). For the 6.0 Powerstroke, Ford suggests that a variation of 25 degrees or more between engine oil temp (EOT) and engine coolant temp (ECT) indicates that the oil cooler has gone bad.

On the other hand, some experts say that the variation should be 14 degrees or less. Remember, you can’t measure the temperatures when parked or idling as the engine wouldn’t be heated up as it would on the road.

You can measure the EOT and ECT through an OBDII scanner. The oil temperature runs higher than that of coolant but shouldn’t exceed by more than 25 degrees tops.

Ford hasn’t provided a temperature gauge for engine oil temp, so you will have to use a scanner. It’s generally a good idea to have an OBD scanner as it can help you diagnose many issues, not just measure oil and coolant temperatures.

6.0 Powerstroke Oil Cooler Location

Did you know that contrary to common perception, modern diesel engines don’t necessarily have the air cooler in the front of the engine?

To replace or upgrade your oil cooler in 6.0 Powerstroke, you should know where exactly to find it in the hood. Now, most people think it’s located in front of the engine, as was the case for most older trucks.

On the 6.0 Powerstroke, the diesel engine oil cooler is located directly below the engine oil filter, which itself is on the top of the engine.

Do I Need a Genuine Oil Cooler?

As is the case with many parts in a vehicle, you don’t necessarily need the OEM part when replacing or upgrading. There are many aftermarket parts that are just as good and don’t cost nearly as much as the genuine part.

In the context of oil cooler, it really just comes down to your budget. Going with the genuine OEM part by Ford for the 6.0 Powerstroke would be a good move. There’s no guesswork as far compatibility is concerned, and you know that it’s quality.

That said, don’t kick yourself if you don’t have the budget for it or want something more affordable regardless of your budget. There are several high-quality aftermarket oil coolers from other companies.

If you’re concerned about their performance, it’s best to go with the one that has some kind of warranty. That should at least get you a refund if the oil cooler turns out bad. However, in all likelihood, that’s rarely going to be the case if you choose from a trustable brand.

6.0 Powerstroke Oil Cooler Replacement

Unfortunately, replacing an oil cooler isn’t as easy as replacing engine oil and filter. Nevertheless, you can do it in your garage with some basic tools. It’s just time-consuming, so you’ll need to set aside a day to do this task at home.

First, you’ll need to remove the intake, shroud, and disconnect the battery in order to get to the oil cooler. You’ll also need to remove some of the hoses carefully. As you get to the oil cooler and remove its housing, some oil may leak out, so keep some rugs and buckets handy.

Here’s a detailed video of the 6.0 Powerstroke oil cooler replacement process with step-by-step instructions, as well as the names of tools you’ll need each step of the way.
