HELP Me please! Abt coolant temp sensor
Okay, allow me to explain why and what I need a help with this coolant temp sensor or whatever is it on passenger side's block or head that have some kind of sensor screwed in between last two sparkplug holes. I was putting engine on the stand and its fell on the floor as its smashed that part and I did not remember what is it looked like so I need someone to tell me what is it and where can I buy the right one for it. As for me being rookie, what connector that connect that sensor as well. Its 1985 TPI and thank you very much.

Yes, on the driver side have that kind sensor, I already pulled that one out and its still connected to the wire. I am trying to find the passenger side one and seem that I have no luck, would be greatly appericate it if someone could send me a link that I can buy that. I am in progress of transferring all parts from old motor into crate motor but I am very new to corvette so I hope that you guys will help me out till the end

Just a guess on my 84 it was the engine cooling fan switch/sensor it turned on the main fan. The 85 may have used this same switch/sensor for the auxiliary fan switch maybe just a guess..Does it look like this..I found this on zips website, just put in the year and coolant switch and it will bring them up...one is a low temp coolant switch, the one pictured is the coolant temp sensor, hope this helps.

Does your wire on the harness at that position have a plastic connector like this ?
If so go to your parts shop and get a ACDelco # D1852B or get them to cross reference to same style unit.
A common fan switch used in 80's Camaros /Firebirds /Vettes and other GM cars
Or you can buy same style aftermarket switch that will turn your fan on at a lower engine temp
as you will need a new plug anyway

So like I originally said above your broken one is the fan switch

if you don't have that stock connector then you can use any temp switch you like
as you will need a new plug anyway

the new connector has a crimp fitting built into it, its easy to do and sets of the primary fan at 195 degrees.

Are these arranged differently every year?
On my 87,
the passenger side (between 6 & 8) is the temp gauge display sender unit. does nothing else. Blade type plug. (the broken sensor in question?)
driver side (between 1&3) is aux cooling fan temp switch..not even an issue if there is no pusher fan. Pin type plug on switch.
Coolant temp sensor for ECM is front of intake manifold. 2 pin plug. Next to cold start switch also 2 pin plug.

on the 85 the left side (drivers side) is the auxillary fan,
on the right side is the primary fan,
I know this 195 f switch works, when we had the snapon reader hooked up to the ecm doing the timing the primary fan came on as soon as the temp hit 195
