Sometimes when I am sitting at traffic lights the temp needle will start to climb towards the red, however, giving a little throttle (usually to 1500-2000 rpm) will cause it to go back down to normal. This would work with my teg when I was low on coolant so I thought that might be the problem but when I checked the reservoir today it was absolutely full, way past the full mark. I am wondering if it might be a bad headgasket pressurizing the system and forcing the coolant into the reservoir, or if maybe a bad water pump is to blame? Any ideas?
