Coolant Pressure / "Head Gasket" Test on a 6.0L Powerstroke

***PLEASE READ THIS!*** This test can help determine if your 6.0L (or any other engine really) has a blown head gasket. However, on a 6.0L it can also help determine OTHER issues as well, such as a bad EGR cooler, or in my case - it lead to diagnosing a bad OIL cooler! In order to distinguish between a head gasket and an EGR issue, you have to take into account OTHER symptoms, such as coolant loss, smoke, and oil condition. Overall PRESSURE is really NOT the problem! It's how QUICKLY it gets there! Your ove, this is NORMAL - especially if pulling a trailer or climbing a long grade. Overall pressure can climb to 15+psi simply due to combination of a full or overfilled system, and high (but normal) coolant temperature. Too much temperature and you will overpressure the system and overheat if you push it far enough! More videos to come!

Bad EGR cooler or head gasket

A quick and easy approach to determining head gasket or EGR cooler failure. This is the method we use every day.

Homemade Coolant Pressure Tester for a 6.0 Powerstroke
My local auto store didn't have a coolant pressure tester that would fit my 6.0 Powerstroke diesel engine's coolant cap. So I made my own with a few 3/8th tees, 5 feet of 3/8th hose, a few hose clamps, a tire valve stem, and a 15psi gauge that I got from Grainger. The whole set up cost lest than $25. Once I figure out where, I plan to mount the gauge inside the cab.
