testing temp guage and sender
 

hello, anyone know how to test the factory temp guage or sender?? need help asap. Thanks, Devin

hook it up to the battery and if it pegs all the way to the right then it works. Now if it is accurate, it isnt, if you wanna know how hot your engine is running then get an aftermarket one, the factory guage is just meant to tell you if your engine is overheating cold, or in between
