Q for order of work.

[BSkopnik]

So I'm going to be putting in a new oil cooler, going to do a full flush of coolant to change to ELC and put in a new thermo and housing along with a coolant filter kit. Now my question is what order would be the best way to do this. Do the oil cooler first then the full backflush and add in my filter/thermo? Now that I read that almost sounds like the better way to do it. Lol

Was going to just replace gasket and orings but bought a cooler just in case. Haven't had any contamination either way as far as I can tell so I'm assuming my cooler is probably just fine ad dandy. I won't know for sure till I get the old one out but almost thinking I might just put the new one in anyways.

Also have done some searching but with the cooler removal is it worth the time to pull the alt out for access or is it fine enough just from bottom and driver wheel well

The oil cooler and the engine cooling system are separate so that is your choice.

I thought that coolant and oil ran through the oil cooler??? We are talking about the tennis ball looking thing mounted right under the driver header?? Because I just had my seals replace and I thought the coolant would also need too be service??

They are separate systems. The coolant is only in the largest radiator. The transmission cooler works the same way, but it only has ATF in it. Look at a transmission cooler on a part website and it has an input and an output for the lines where the ATF goes.

I know those are seprate I replaced my stock trany cooler with a 6.0L, but I thought he was talking about the engine oil cooler, which is on the side of the motor. But then again I'm easlyconfused

Coolant and oil both run through engine oil cooler yes. Coolant runs through middle of cooler and oil runs through outer over fins and the such.

Ill be doing a 6.0 tranny cooler too real soon. Got the cooler sitting in box on shop desk. Need to get rest of parts. Hoses splices the such and in she'll go. Did you take off the bumper and such or do it all from top side?

I took the whole front of the truck off, bumper,grill, grill support so it made it real easy to swap out the cooler's, took about 2-3 hours total.
