recerntly, my temp guage as been sitting in the red. I think the temp guage might not be operating correctly because the motor does not show any signs of overheating. When i lift the hood, the engine compartment seems to not have excessive heat. The engine seems to run fine without any detonation. i put one of those laser temp guages on different parts of the motor and it reads about 199 on the block in between the exhaust ports. when i drive on the freeway, the needle still stays in the red. Is it safe to say the guage is not operating correctly?
