Much discussion has been given to why the EGR coolers fail on the 6.0L Powerstroke, but little to why the oil cooler fails.  The good news is, failures can be prevented!

A search of the internet will give you dozens of websites speculating about all sorts of theories, but one thing for sure is the coolant passages in the oil cooler plug up and this is what leads to EGR cooler failure.  See link for technical details.

Preventing oil cooler failure has been a bit of a challenge until recently, with the creation of a reasonably priced coolant filtration system.

Precision Auto Service has researched the available coolant filtration system and has brought in the Dieselsite coolant filtration systems.

Coolant Filter

Coolant filters are not a new idea to the diesel engine world. They come in most OEM applications for medium duty and  tractor trailer rigs. The idea was somehow tossed aside for light duty applications, most likely due to cost.

For the Powerstroke, coolant filters are a very important issue that needs to be addressed. Many diesel engines – like the Powerstroke – are cast with sand at the factory.  This sand is NOT completely removed from the system, in fact, lots of this sand can fall out of the casting over time. The sand can wear away at water pump seals, hoses and radiators and removal of this sand can greatly increase your water pump life, but more importantly, it can prevent plugging of the factory designed Engine Oil Cooler.

The DIESELSITE Coolant Filter Install Kit will remove the loose particles in your cooling system and give your water pumps, radiators, heater core and engine oil cooler the protection they need from these abrasive and plugging materials. Wear and plugging is greatly reduced by the removal of undesirable elements in your cooling system.
