ok. my car overheated. i took it to a reliable repair shop and they wanted $900 to replace the radiator and thermostat. thats what they figured was wrong. so i paid them the $150 for their time and figured i can replace them myself. i found both, brand new for $250. does anyone have any tips on the replacement of the radiator and thermostat. the radiator seems pretty straight forward. the thermostat seems different. any help will be appreciated.
