Hello, I have a 1970 Plymouth duster with a 400 Chrysler out of a 1973 satellite. My question is this; my engine shows temperatures of around 235° on the sensor located in the water pump. I have a in-tube sensor on the output hose of the radiator near the thermostat. It shows about 190 at the same time, which is the same as my thermostat. When I shoot the block with a heat gun. I showed it to be around 200. Where is the right temp?! The radiator exterior shoots at 188 at the same time.
Thanks
