I got a coolant temp sensor from the local part store for a 2000 Camaro ls1. Not a gm brand sensor. My problem is I have my autometer gauge in one cylinder head and bs3 sensor in the other. Bs3 is reading 210 degress while autometer reads 190.

What gm coolant temp sensor part numbers do you guys run in ls motors?

Thanks

 

That's a common reading because of the temp difference from the front left to the rear right.
