Car runs for 3 minutes or one kilometer then the temp gauge goes to red line\nhot. Turns off engine and wait for 4-5 minutes to cool and it goes back to\nmedian. Runs again for 3 minutes or about half a mile or one kilometer and\nthe gauge goes up again to hot.Was able to limp home using this cycle.\n\nUpper radiator hose is very hot, lower hose is is just lukewarm. Got home\nand allowed t he engine to cool a bit. Removed the cap. Revving the engine\nand peeking through the open radiator cap doesn't produce any water flow but\nthe level rises a bit. I don't think its the head gasket for I don't see any\nsmall bubbles coming out.\n\nCould it be that the thermostat is stuck closed? Pump defective?
