Hi guys,
I just bought an 18k mile 87 iroc with a built 355 in it. I got the original 15k motor with the car and am putting it back. QUESTION... Theres a coolant temp sensor in the front of the TPI intake and a coolant temp sensor I believe for the temp gauge in the side of the driver side cylinder head.
Is there suppost to be a sensor in the passenger side cylinder head???
If so whats it for? thanks ! Steve

With a single fan there is no sensor between cylinder 6&8 in the head. Just a iirc 3/8 not plug.

My iroc has dual fans so there's a fan switch there?

Yes, it will look like a knock sensor connector.

​​​​​​​ Thanks!
