Where is 6.0l egr valve

In fact, many EGR valves begin to stick within 20, miles. Roughly percent of all EGR cooler failures are the result of a plugged oil cooler starving them of coolant, hence the reason we spotlighted the oil cooler as the 6.

With a lack of coolant supply making it to the EGR cooler, its ability to drop the temperature of the exhaust gases that need to reenter the intake tract is reduced significantly. When enough heat builds in the EGR cooler this is what you get: a ruptured internal core.

Over time, an insurmountable amount of carbon deposits accumulate internally, hampering exhaust flow. Even without coolant supply being restricted or cut off due to a bad oil cooler, the 6. Here, you can see where coolant leaves the oil cooler and also where it enters the EGR cooler. Without a doubt, the antifreeze in the 6. Being in constant indirect contact with 1,plus degree exhaust gases via the EGR cooler takes its toll, and the coolant begins to break down in a fairly short amount of time.

This breakdown often contributes to the plugged oil cooler scenario we discussed in Part 1 , where gel-like debris becomes lodged in the narrow passageways of that heat exchanger. Ford recommends flushing the 6. Being that EGR brings so much exhaust back into the engine, it stands to reason that a higher soot particle count appears in the 6. The EGR cooler design was changed slightly. The redesigned EGR cooler 6. This cooler should have cooled the exhaust more efficiently. The Ford Powerstoke 6.

These coolers are failing just like the 6. We have many customers that have experienced engine failure due to the engine hydro locking when coolant is introduced into the engines intake manifold.

Many trucks have had the cooler replaced multiple times in the first , miles. The engine oil cooler passageways are very small and become restricted with engine casting sands. The casting sands from when the engine was made. The sand is released over time and gets trapped in the oil cooler, restricting coolant flow into the cooler.

An EGR valve that sticks in the closed position provides no EGR flow into the incoming air stream and noticeable symptoms are typically low, although this has been known to contribute to an over-boost condition. EGR valve issues should trigger one of the following codes:.

There is a retaining clip on the rear of the EGR valve connector that must be released, then the connector can be pulled straight upwards. Be careful not to lose the bolts in the engine valley. We advise loosening the bolts, then finishing to remove them with a pair of needle nose pliers.

The bolt to the right is particularly difficult to reach by hand. By tilting the valve slightly to one side, this tool can be used to pry the body of the valve upwards.

Once the o-rings have been unseated, it should come out with ease. Note - it is completely normal for the valve to be absolutely packed with soot.
