oil cooler failure seems to be quite a common occurence with omegas when they get to a certain age, and it's a problem that rears it's head on the help pages here quite often. i had an oil cooler failure recently, well documented on this forum, and subsequently i have been asked about the parts required for the repair by quite a few members. hopefully the following will help anyone in a similar situation; illustration and part numbers (based on repair on 3.0 v6):
1. 90424578 HOLLOW CHANNEL BOLT FOR COOLER RADIATOR
2. 11076852 METAL COOLER O-RING
3. 93176626 COOLER RADIATOR AND COOLER PLATE (INCLUDES NUTS)
4. 93165267 SEALANT (GREY STUFF (MAY COME IN DIFFERENT PACKAGING))
5. 90409175 O-RING BETWEEN COOLER PLATE AND COOLER RADIATOR
6. 12992646 HOLLOW CHANNEL BOLT FOR COOLER BRIDGE
7. 12992647 COOLER BRIDGE SEAL
ALSO THE FOLLOWING (optional, not pictured)
8. 90502201 THERMOSTAT
9. 9128363 THERMOSTAT O-RING
10. 9129999 COOLANT TRANSFER PIPE O-RING (FEEDS INTO THERMOSTAT HOUSING. ORDER 2 OF THESE)
i would advise doing the thermostat at the same time as this job as you're already in the affected area, however, if you're convinced yours is fine then this info can be ignored.
the illustration also features a gasket sitting beneath the cooler plate. this is not required as the correct sealant will do the job and is no longer supplied by vx, however, i have included it in case you find one when you take your cooler plate off and wonder what it is.
finally, a point re items 1 and 6 (the hollow channel bolts). these are not essential items to replace as they may well be in good condition on your vehicle, however, considering the low cost involved in replacing them i have included the part numbers here.
oh and don't forget the new coolant
