Subject: Re: Overheated at the drive through Zoo by CentralCoaster on 2009/7/24 18:55:15 An 18 yr old car with only 40K on it and in that condition has probably been sitting awhile. The radiator is probably half blocked up inside and out. Check for corrosion and deposits in the radiator. And maybe a few plastic bags and leaves in front of the radiator. Depending on the condition, you might be better off replacing it. I would also flush the coolant passages in the engine block out thoroughly with a pressurized hose. That chemical crap you buy in bottle isn't enough for a block with a thick layer of corrosion and slime. The temp sensor should not be dropping to 60F, even with an air bubble. That air bubble is still pretty damn hot from the hot water and steam surrounding it and conduction from the metal. I would try to duplicate that condition and check the resistance of the temp sensor and compare with the factory specs and possibly replace it. Don't the LT1s have two different temp sensors that can be read on the dash? Why not compare these? |
