Oil Cooler Leak Fix
Hi,
I have 3.0 2012 CRD and have noticed small deposits of oil in the expansion tank. I believe it is because of the oil cooler. Engine oil is still jet black so it means that it has not made its way to the engine yet.
I need your valuable suggestion on the approach to fix it.
Approach-1
Buy a cooler assembly along with oil filter housing and install it
Part costs 1650$
Labour quoted: 5 hours
Plus oil and coolant
Approach-2
Just buy a cooler and replace it while the housing is still mounted on the engine. The mechanic says to replace the entire housing so that there are no future leaks in the oil filter assembly.
Parts cost 350$
No cost for labour but I believe should be an hour or so.
Approach-3
Buy cooler and all gaskets and remove the cooler and filter housing and dismantle it and install new gaskets
Parts cost: 350$
Labour quoted: 5 hours
What do you guys recommend ? am I alright just to go with approach-2 and still have peace of mind??

After having a good look at mine I would choose #2 as with other vehicles it always seems to be just the cooler itself that craps out not the rest of the unit, I see the dreaded Tork screws are used as well.... be a prick of a job I think, remove air box and in my case the catch can to try and get some hand room... a ratchet drive with torx heads a must.
Bound to be someone on here who has had the misfortune to replace one...

PS: you will have to give it a damn good cleaning with a good cleaner to get the oil out, if it is allowed to get into the hoses too much they will rot.

Would suggest replacing the oil cooler water hose while you're at it, they fail. Caught mine just in time - internal split wasn't visible from the outside. P/N 68147604AA

Would I need to drain engine oil prior to this? I assume ill have to drain the entire coolant though.

Given how much modern oils have improved, especially full synthetics and their tolerance to high temperature, you do wonder why the bloody things are even necessary.

Coolant has to be drained for hose replacement. You'll need fresh coolant anyway if you have oil contamination in the tank.
