I was putting my headders on a 88' IROC and i hit a sensor on the right side of my engine block. I took it off and it pissed out radiator fluid. I have looked at my GM book and a haynes book and both dont say anything. Was wondering if anybody knew what sensor it was. Oh, its not my coolant sensor either.

 

on the drivers side you have engine temp. sensor (gage overheat)

by the oil filter is the oil pressure switch.

then on the passengers side is the coolant fan switch
and the esc knock sensor.


so i am guessing since you said right side(drivers side) by the first 2 spark plugs it must be the engine temp.sensor

 

too hard to tell, i can't see you breaking tye temp switch for the guage because it's all metal. and just by putting on headers it must have been a big hit. if it is plastic its not the temp switch. if its all metal i would say the temp. switch although you must of hit it hard to bust it like that.

 

Well I assume right hand side means passenger. So if it is and it goes into the block, just above the oil pan rail, it is your knock sensor.

 

but if it was the knock sensor should it leak out antifreeze like he said?.. well he hasnt responded to anything so who knows

 

sorry i havent responded, but i have been pretty busy. But anyways, it had a plastic end on it where a single wire connected to it. I decided to take it off and anti-freeze poured out. So, im not sure what it is, but im going to look into my books again and see if i cant find what it is. Thanks to the reply's.

 

I believe that the know sensor does go into a cooling jacket but can't remember for sure.

 

is it by the 2nd spark plug that one??? see if you can be more specific on the location..later

 

probably the secondary fan switch

 

wait the one by the spark plug on the drivers side is for the temp gauge(according to the manual)

 

well he ever did actualy say which side of the engine.. besides the right.. but yes if he ment drivers side then the temp sending unit is on that side...
