My Haynes Manual says Parenthetical (..) comments are
mine):

2) remove oil filter.

3&4)  clamp coolant hoses to and from oil cooler (or
get ready to plug them when removed).

5)  remove nut in the middle of the oil cooler (a
collar nut around the thing onto which the oil cooler
screws - ed.)  Remove the oil cooler and recover the
o-ring.

6)  use new o-ring when refitting.  Clean oil cooler
and block mating faces and coat with suitable sealant
(vw amv 188 101.02 or equivalent) and being careful
not to get any sealant into the central area sealed by
the o-ring.

7) with the o-ring and oil cooler in place, re-fit
central (collar) nut and tighten it to the specified
torque (torque not given). check that the oil cooler
is not fouling any adjcent components (whatever that
means).

8)  re-fit and secure coolant hoses with clamps.

9)  fit and tighten oil filter in normal way (smear
some oil on rubber seal etc), and hand tighten only.

10) check coolant levels and oil levels and

11)  start engiine and check for oil and coolant
leaks.


Sounds like it's not too bad of a job, its an o-ring
you need (not a gasket) and some sealant.

I'll add step: one needs to purge the coolant of air.

good luck,  Malcolm
