Oil cooler

[outlawpowerstroke]

Ok so what's the easiest way to get the oil cooler out to fix it cause it's leaking.ive done one on my 7.3 Idi before and I really don't wanna jack the motor up again but I guess I will if I have to.

Drain oil and coolant. Remove filter and block heater element.

I have always unbolted the rear mount(filter mount) and pull the cooler out of the front. For me it's been easier then wrestling the entire unit out in one piece. Then remove the front mount. Clean everything and replace Orings obviously. Reinstalling I have done both ways but again I find it easier to install the front mount and new gasket by itself. Install the tube to the front mount with its new orings. Then slide in that unit to the front mount and install the rear mount to the block. It's not fun and it's not easy. But that's how I've done several of them rather then installing the whole unit as one.

Definitely like stated above. Trick is once the front adapter is on take the tube and rear adapter hold it in place and you can take a prybar between the exhaust manifold and cooler and press it together. If the block heater is seized in don't worry about it I have left them in before and never had a problem. Good luck I just did mine last month

Try using a ratchstrap to compress the cooler after lubing the orings. Bolt in one end fingertight and then compress the assembly.

The way I've always done it is take filter off, pull block heater. Take a shower in the antifreeze that comes out. Remove bolts. Front I usually take the tire off and come through wheel well with some extensions. Pull aseambly out torwards transmission. Get a rubber maleate and hit ends off. Replace orings, grease! I use a press because I'm a scrony feller and don't have enough lead in my a$$ to get the caps back on. Getting the cooler back up in can be a pain. Make sure you don't have your tongue over your eye tooth. It'll go in. Replace the gaskets. I put the front two bolts in first. The assembly should spin to catch the back 3. Torque specs are 18 ft lbs I believe. Teflon tape on block heater. Replace or put filter back on. Add coolant and oil as needed.

That's how I've always done it. Never had oil in antifreeze or vise versa and I've done 4 of them.

Also make sure they're ford orings. Diesel oring has them for 75$ or so.

I pulled it whole. Left the heater in also.
Mine went in real easy also.

Well it ended up just being from water in the filter I think. I let it run for awhile and it went from milky to black so it evaporated what water was in there lol
