I would drive up a grade or hill in San Diego and my temp would go from 82C to just under 100C rapidly. So I'd pull over and check the radiator. Half would still be relatively cold like the coolant wasn't flowing enough. I tried 4 different thermostats with the same results thinking they could be sticking or broke. After the thermostat relocation my radiator has even heat through out very quickly. The engine gets up to temp right away and stays consistent no matter how I'm driving now.
