Re: 3.3 Grand overheating after lower rad hose
Usually it's not a problem but, if you have to, take off the radiator cap, turn the front and rear heater on full, and let it idle about 15 minutes. Just keep the radiator toped off with a 50/50 mix of coolant and distilled water. Make sure the fans kick on. Turn it off, put the cap on tight then give it a test run.
