So yesterday im sitting in my driveway at idle, and i notice my temp gauge shoot towards the heavens. So i quickly open the hood, only to see a crack in my radiator, and it shooting coolant all over the place. Today i replaced the radiator,and just now filled it with 50 50 coolant and water. turned it on, let it idle, and once the thermostat opend i filled it up more, just like normal. I let it idle some more and the second i get on the gas the temp gauge shoots up again. Im completely stumped. I would say thermostat, but it opened and functioned fine. any input is greatly appreciated.
