What is this thing called?

[Andrew]

I don't know the proper name for it... it's the sensor with 2 prongs above the oil filter.

Thanks

It`s the coolant temp switch. It tells the fan when to come on.

Hey Andrew, which book did you get that out of? btw, is that the same one seen in your head gasket threat?

 

[Andrew]

It's a .PDF shop manual for a Civic/CRX I downloaded from the 'net.

I've got a file I can Email you. It's about 7mb.
give me your Email and I'll try to send it over.

What? that doesn't have anything to do with coolan. It is an oil pressure sender that clicks on when your oil pressure goes lower than a certain level and then your oil pressure light comes on.

No, thats the oil-pressure switch, which is the Single Plug(the one in the picture I posted).

The 2 prong sensor is indeed the Fan switch/coolant sensor
