Where is oil cooler on 6.0 powerstroke

Pictured here is the optional cold weather kit, which has a thermostatic-controlled flow for faster engine warm-up This is the problem child… the factory 6.

This cut-away of the cooler shows the tiny oil and water passages inside. Debris in the cooling system is what causes the coolant side of the oil cooler to plug up, which can cause major issues downstream, including killing the EGR cooler.

The install starts by removing all the stuff on top of the motor including the turbo and intake manifold. DW This plastic filter sits in the oil reservoir under the factory oil cooler and is supposed to filter the oil headed to the HPOP.

This is another failure area on the 6. This is what the factory oil filter assembly looks like outside of the engine, complete with cap and dirty filter. This setup will be mounted to the new Bullet Proof oil transfer block assembly. All you have to do is install the new gasket. Another new gasket goes under the factory oil filter base. With the gaskets in place, the factory oil filter assembly can now be bolted to the Bullet Proof Diesel manifold block. The new assembly sits on top of where the old oil cooler was located.

Once bolted in place, you can reattach the original sensors and coolant line fitting which runs to the EGR. Now, attention is focused at the front of the truck. Both are removed from the truck. Some 6. While this increases their surface area for better heat transfer, it also makes these passages easier to clog. Contaminants in the cooling system from corrosion, additives, and gasket material can work their way to the cooler, which may seal up passages over time. It is possible for dirt, soot, and sludge to cause similar blockages on the oil side of the cooler.

The oil cooler sits in the valley of the engine, where it is exposed to massive amounts of heat. This can reduce cooling efficiency and increase thermal stress on the cooling block. In some cases, extreme heat and stress may lead to splits in the fluid passages, allowing the oil and coolant to mix.

This creates a sticky emulsion that can create a real disaster inside of the cooling system. The oil cooler retains a protective screen, that helps to filter the oil being diverted to the high-pressure oil pump HPOP.

The oil supplied to the HPOP, is then converted into high pressure oil, which is used to drive the fuel injectors. Even if the pump is still working, debris passing through a broken filter could find its way into the injectors and cause all sorts of problems.

Symptoms of a Failing Oil Cooler If the oil cooler is working effectively, the oil temperature and coolant temperature should be about the same. Oil temperatures more than 15 degrees warmer than the coolant temperature, during unloaded not towing , highway speeds, may indicate a failing or restricted oil cooler. After passing through the oil cooler, the engine coolant is directed to the EGR cooler. If the movement of coolant is restricted inside of the oil cooler, it may lead to overheating and eventual failure of the EGR cooler.

Bullet Proof Diesel offers several solutions that address the pattern failures of the stock oil cooler. Installing a 6. This remote location also allows you the ability to backflush the cooler periodically to help prolong its life. Another option completely eliminates the factory 6.

In this case a large air-to-oil cooler will be mounted in behind the air conditioning condenser and heavy duty oil hoses carry the oil to and from the engine.

Our oil cooler relocation kit moves the stock cooler out of the engine valley. This keeps the stock oil-to-water cooling setup. The cooler mounts to a bracket that attaches in the engine compartment next to the passenger side battery. HEUI —this is about as serious as a heart attack.

The oil cooler loses its efficiency little by little as the tiny coolant passageways gradually become blocked over time. The blockage is primarily made up of a mixture of casting sand from the block and heads, along with suspended solids reminiscent of gel left behind when an incompatible coolant begins to break down. As this buildup continues to pinch off and then eventually block coolant flow through the heat exchanger portion of the oil cooler, oil temp begins to climb.

Not only is this boiling hot oil no good for the injectors, high-pressure oil pump, turbocharger and engine bearings, but the blockage starves the EGR cooler of adequate coolant supply.

A temperature difference of 15 degrees or more between the two parameters usually means the oil cooler is in the early to moderate phase of plugging. To pull off an overhaul of the 6. As part of the 6. But one look at the lifter valley and you know a lot of work lies ahead in order to access and ultimately remove the oil cooler. Components like the turbocharger, intercooler piping, fuel filter reservoir, oil filter housing, intake manifold and EGR valve all have to be removed. Here, the oil cooler is being rebuilt in addition to addressing a blown head gasket and a blown EGR cooler, the latter of which was likely caused by a plugged oil cooler.

After the oil cooler mounting bolts are out, a 21mm socket and hammer are recommended to handle the dirty work. The heat exchanger portion of the oil cooler is at the epicenter of any 6.

Gasket, O-ring and seal failures are actually very uncommon, but everything needs to be replaced once you break the seal.
