You could probably tackle this safely if you possess solid journeyman-level auto mechanical skills. If you own the manual and you study up first using all the information on the net, you likely can get by with just a little less skill.

There are two ways to go on this job:

1. You replace the heat exchanger with another heat exchanger. This obviously leaves in place the possibility of future failure of this component.

2. You replace the heat exchanger . . . . period. Meaning you remove the existing exchanger, bridging across where it connects, and replace its function with an aftermarket oil cooler. I'm talking about an oil cooler which moves heat in the oil straightaway to the passing air, rather than exchanging the oil's heat into the cooling system.

Some here might not agree, but I think option 2 requires more mechanical savvy than option 1.

So bottom line, either way you go, it requires a pretty fair amount of mechanical acumen to undertake this work. You will not be tearing the engine apart to where you'll be clutching pistons and con rods. But you will be removing enough of the engine externals to matter, and enough to be in trouble if you don't know what you are doing.

You didn't tell us about your car, the year or how many miles. But at 800 bucks bear in mind you can buy an entire Cat engine for circa double that, give or take. If your engine already has high mileage, it might be something at least to consider.

Sorry you ran into this problem. Hope you escape from it soon and are back on the road in good shape!:thumbsup:
