Cooling Troubles... - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Ok, I tried tuning my truck a bit to get my gas milage up a bit. Its been running like a champ, I messed with the carb a bit and advanced the timing a degree or two. But ever since I did that the temperature gauge has been all over the place.

Im not sure if the temp gauge has anything to do with me tuning it, but... I checked the radiator and it had a bunch of overflow in the container, so temporarily I added some fluid to it. Still the gauge is all over the place. My heater wont even heat up and its a brand new heater core (not even a year old).

Any Ideas what It might be? Temp sender? Thermostat? Radiator?

I know I need to flush my radiator and its in need of an oil change, but what else might be the problem?
