Ok I can't figure this out. I was driving the car yesterday and the temp gauge was reading all the way cold. After about a mile all of a sudden it went all the way hot. I was only a block from home so I pulled in and let it cool off. Today I pulled out the thermostat to make sure it was working properly and it is. I heated some water to 180* and poured it over and and sure enough it opened right up. I put everything back together and let the care idle for 5 minuents. The tempature gauge never moved. I shut it off and checked under the hood. The over flow tank was filling up and when I took the radiator cap off it had plenty of pressure on it. If you put you hand on the pipe comming from the thermostat it was hot, at least 100* but as I moved my hand down the pipe and across the upper radiator hose it was cool. I put my finger in the coolant in the radaitor and it was stone cold. Not a bit warm. When I turned on the heater in the car it blows nothing but cold air. It's like something is blocked in the coolant system but I don't know where. When I filled the radiator it pushed water out the overflow cap that you unscrew from the thermostat housing and if you squeeze the top hose it raises and lowers the amout of coolant in the radiator so the radiator is not blocked. The water pump is only about a year old so it should be good. So it seems I have two problems. The temp gauge is not working and the coolant is not flowing. Any ideas? I'm stumped.
