do you have an IR temp gun? they're cheap, and can save a lot of guessing. you can point and shoot, getting exact temps from the hoses, heads, intake and even the radiator. several guys have mentioned it, and it's a great investment. i even use mine to look at exhaust temps coming right out of the ports, looking for misfires (colder) or a lean cylinder (hotter). i'd trust a digital IR reading before i'd trust an electric gauge and sending unit.



So of the IR temps shows 200 on the water pump housing right at the sending unit are you saying the water temp should be 200 also?
