I have an oil leak right behind the oil filter. There is a wire connected to it and the oil is leaking from where the wire is connected. How do I stop the oil leak.

Freeze plugs only leak coolant. It is likely that the oil is coming from above it.

It has an air cooler. There is a lot of information on Durango oil leaks here

..

it might not be completely tightened down by hand all the way

could be the oil cooler leaking. its located behind the oil filter.

possibly oil pressure switch which has one wire going to it near oil filter or split oil pump gasket or crank seal, might have to remove timming belt cover and crank while cover is off to locate leak

check for oil presser sensor leaking these things will leak right threw to the wires even so unplug and look real close and when u change filter make sure to wipe mateing surfaces

there is a rubber seal behind the oil cooler(that is where the hose connects) the best thing would be to remove the oil filter and oil cooler to replace the seal. I would at least remove the oil filter and try to tighten the large nut that holds the oil cooler on and see if that stops the oil leak

From your description you are likely looking at your oil pressure sending unit. If it's leaking, replace it. Have your parts guy look at it if you can just to make sure it isn't something else....he will (should) know right off...Only problem is I can't see it from here!!!

Good luck !!

No. Please do NOT use silicone. The oil pressure there is very high, and it will blow the silicone right out.
...What you CAN do, if it is leaking real bad, is to take the rubber gasket off of the oil filter, and use that gasket behind the oil cooler, to the block. You will need to buy a new filter, though.
The gaskets are almost identical, until you get a new one from a Toyota dealer.

This should get you up and running. Thanks for choosing FixYa for assistance.
The graciousness of a FixYa rating would be most appreciated.

i believe you are looking at the oil cooler, replacing the gasket is not that difficult, drain the radiator, remove the oil filter and it should be 4 bolts and the whole assembly comes off, keep in mind though its more common for the oil filter itself to be leaking rather than the oil cooler gasket.

You need to clean the engine and then run the vehicle while watching the area. The most common failure is the oil sending unit located near the oil filter. I have also seen a leak develop between the oil pump housing, which is mounted directly behind the hamonic balencer and the engine block.
