temp sensor sender 4000q.which is which
I believe both sensors on the right side of the block on the cooling hose/thermostat housing send one signal to the computer and one to the guage. My guage reads too hot or cold sometimes after up to temp for years(I know) and believe the sensor is messed up because the fan goes on and off as it should. Which one do I replace, upper or lower and what is it called on a parts site? thank you.
