Title: water temp sending unit
Post by: soprano on July 13, 2016, 04:18:52 PM: I have a question it's a rookie question.. if I have an autometer water temp gauge and as soon as I turn the key on with the motor being Stone Cold the meter jumps to 200. So here lies my rookie question , do I need to have an autometer sending unit or if I put a different brand sending unit would that give me false readings??

In order for the gauge to work properly you should be running this sending unit (ATM-2258). You can find it at summit for about $16.00 + shipping
