just installed brand new thermostat and radiator but it's still running hot and the water in the radiator is not flowing, it just sits there even after it gets hot enough for the thermostat to open. don't know what next to try
Are you getting very much heat in the cabin with the fan on high and the heat control all the way hot? If not getting much heat out of the heater then change the water pump. To be sure the pump is bad remove the thermostat and reattach the radiator hose and fill it up and run it and see the water should flow really well, which I don't think will happen on your car. There have been some cases where the water pump fins have worn down or clogged with debris and wont pump the water.
If you plan on keeping the car for a long time you may want to invest in a lifetime warranty part. It could save you money latter.
