Running temp?
hey guys, so I’ve been doing so reading on the running temp of the 1987 2.8 MPFI v6 and what temp the fans turn on. Idk the running temp but I’ve read the fans turn on at around 235? That seems a bit high to me. Can anyone confirm or deny this I really need the info!! Running temp? And what temp the fans SHOULD turn on at? Thank you so much!

Re: Running temp?
If you are worried you can get a SW555 (89 turbo trans am) fan switch 211F try rock auto and a 180 stat. They should keep everything nice and cool. I would not go any cooler than that also don't put the fan on temp too close to the thermostat.

Re: Running temp?
Here are the factory switches
https://www.rockauto.com/en/catalog/...an+switch,4312
like I said the 89 turbo 3.8L trans am has a direct bolt in lower temp switch

Re: Running temp?
Sounds like you have the wrong connector. What you posted only controls the gauge not the fan. Either you are looking at the wrong sensor or someone modesm your car a bit because getting the right one was too difficult for them

Re: Running temp?
If you dont have a gauge then all it does it turn on the idiot light
