agreed. however the drill/tap needs to be VERY perpendicular to the mating surface or it might leak. ive heard of some that try to use plumbers thread tape to stop seepage. not recommended.....the sensor needs contact with the head to ground.

cheers, jason

Obviously you will need to connect the correct wire at the X20 (out of two coolant temp wires) to the correct single wire in the C101. This isn't hard.
