just did gsr swap and after it warms up the autometer gauge reads 200-210 while driving and goes up to 230 in traffic. the factory gauge does not show its overheating though. also the fan is working and i put a new 180 thermo in.

 

where did you put the sensor on the autometer gauge?

 

front waterneck in the cavity that is allready there on the front side 00gsr.

 

Well my gauge read 200-210 during driving or normal traffic. Sound normal to me and don't sweat it if your fan is kicking on.

 

check your grounding of the sender.

180-185 on the highway, fan cycle on at 205, off at 200.
