Removing Oil Cooler

[Jcslocum]

1989 3.2

I have a very significant oil leak coming from the cooler just where the rubber oil hose connects. The oil comes right out of the core in the last opening of the cooler. Pouring out as soon as the engine fires.

Can the cooler be removed with the engine in place?? Looks to be easy on the bottom bolts but the top bolts are invisible and I'm not sure they can be seen without dropping the engine.

There are no leaks from the Triangle of Death area and those parts are dry. Believe it or not :=)

The cooler doesn't appear to be damaged in any way nor does it seem distorted or deformed from what I can see.

Any help would be appreciated!!

Jon,

Have you done a search "Engine oil cooler removal"?

Do you have a Bentley?

No engine removal required.....

Good luck,

They say it can be done in place. Think a partial drop may be required.
The coolers do spring leaks .......mine did. Confirmed after i dropped the motor and made a pressure tester.
Sourced a good used one here on Pelican.

Definately can be done w/o dropping the motor.

You must drain the oil and remove the S hose from tank to cooler. Then go to the topside of the motor and remove the air filter to gain access. Remove the sheetmetal on the rt side and rt front of the motor that surrounds the cooler. Clean the top area thoroughly, remove the Air Duct that connects the cooling air going into the top of the oil cooler, then clean the same area again thoroughly. You now have access to the (4) M8 hex nuts that hold the cooler in place.

Once pressure tested at the dealer or local Porsche service shop you can install or replace it as necessary. When installing, make sure you use only new Factory seals. The aftermarket ones are too short and will leak immediately. Info on this has been posted here on Pelican.

I use a little grease on the seals to hold them in place while fitting the cooler back against the motor.
