Just breaking in my rebuilt 250, and noticed that the temp guage starts at cold then slowly raises and then max to hot within 20 seconds and stays there. I immediately thought that I had an overheating problem, but the thermostat (195 deg) hadn't even opened up yet so I know it's not overheating.
I did install a new sender, could it be that they gave me an idiot light sender instead of the guage sender, could it be the guage, or is it the wiring?
Thanx in advance
