Leaking oil thermostat or sender
Earlier I mis posted asking about a leaking engine mounted oil cooler. I meant to refer to the engine mounted thermostat. It appears its leaking or the sending unit right next to it. I can find the part # for the thermostat but I can't tell from the parts diagram what exactly is the sensor/sending unit thing right next to it. It has a single spade connector with a green wire (24mm BTW). The oil is pooled around the base of both of them so I'm going to clean it up then run the engine to see if I can tell where it's coming from. Per Wayne's book I should be able to replace the o ring on the thermostat without dropping the engine but what about the other sensor?
TIA,

That is the oil pressure switch. If you can get the thermostat out wihtout dropping the engine on your 3.2, you should get the oil pressure switch out too. Buy a new one, since it is cheap to replace and comes with a new seal. The threads on it are only about 3/8" deep and the diameter is only about 1cm. If you can move it up 3.8" out of it's location, you should be able to replace it.

Thanks, I can see that what it is in my Parts and Technical Reference. The diagram there shows it going into a banjo fitting but I don't see that on my engine...is it "hidden" down below the switch under the shroud?. It's 24mm but I'll need a long socket to remove it.
Thanks
