Overheating

91 camaro 3.1. The gauge shows its overheating but the coolant in the radiator is staying just a bit warm and the thermostat is opening. Any help would be appreciated thanks

Re: Overheating

The factory gauges do interesting things, if you dont think it is actually overheating grab a new temp sensor and maybe an IR temp gun from harbor freight

Re: Overheating

Its the factory analog gauges and the gauge wasn't working before so I replaced the temp sensor already and that's when it at least started working

Re: Overheating

How hot is "overheating "? These gauges can be a bit off, a cheap temp gun wouldn't hurt to double check

Re: Overheating

Well something isn't working right

look at your fan relay on the firewall near the brake booster, it has rounded edges and 4 wires running to it. One is black with a red stripe, another is green with a white stripe, and I can't remember what color the other 2 are the point is run a wire from that green wire to a ground and turn the key ON. Your fan should come on now, and your problem is likely something with the temp switch....

best of luck

Re: Overheating

It was wired to a toggle switch when I got it but when I pulled the old engine and installed the new one I ripped that out. Might just wire it back up that way. Thanks

Re: Overheating

I've seen some members wire their car with a switch and another generic relay, so that your fan system will still work stock, or you. can force it on with a switch

Yeah I've seen that too, it was wired with a switch so I'll probably do that again

Re: Overheating

True lol, I'm still wondering why the coolant in the radiator is staying cool enough for me to put my finger in it after the thermostat has opened tho

Re: Overheating

I never tried touching it hot, I'm just happy enough not seeing smoke billowing out the hood

Re: Overheating

Haha that was me when I first got my car, it was so much fun bringing her back to life! When she wanted to die on the side of the road, not so much

Re: Overheating

Lol she's still got awhile before she's road ready, but it at least runs now. It sat for like 12 years before I bought it
