on my italian car, if the cooling fan on the rad dosent come on, i know where to find the sender and how to test it. on this 90 integra, im lost. the book isnt much help. it covers too many models. does ANYONE know where the sender is and how to test it? this car should have been been back on the road a week ago. any help is appreciated.

 

It's a two wire connector on the thermostat housing, it looks exactly like your coolant temp sensor. Actually, it's the only sensor on your thermo housing, so it should be pretty simple to find.

 

thanx for the info. it will be very helpful. i think i found the problem, but ill check that anyway. i found the relay for the rad fan, what a mess. one wire is in original shape , two are spliced together, the other, i think its yellow i, is just hanging ther. the relay and its connector are badly corroded. ill need to locate a replacement section and cleanly splice it in to repair this mess.

 

spiderrey,
