E350 Oil Cooler Replacement
Hi,
I have a problem with an oil leak, it looks really wet around the oil cooler and as a result of the leak, around the tensioner too.
I've also noticed oil appearing in the coolant. I'm going to replace the oil cooler, gasket and the expansion tank. My question is:
1) Anyone happen to have a WIS diagram for the oil cooler on a 272 engine?
2) Is this a straight forward procedure?
3) does the Power Steering Pump need to come out too?
Heres is also another question I've thought about:
what does oil do to coolant when it's mixed, I know that the measures are not that significant, but if anyone has any knowledge, I would be interested.
Many Thanks!

1) Does the power steering reservoir really need to get pulled to get the oil cooler off?
I know the book says, yes, but looking for someone with experience.
2) Is this a true reservoir? (as in fluid is going to pour out and need to be refilled)
or is it just an expansion tank as described by MB? (Some fluid might drip, but loss is minimal)

Negative, you can get by without removing PS reservoir. Hope this answers your question.

Will have to see if it is worth the stress.
Might just pull the PS reservoir.
Wonder how hard it is to get the clip off and back on?
Wonder how much fluid spills?
