The reason you get hot air on high is probably the high speed produces enough pressure to move the door towards the coolant heat exchanger.If the radiator had a partial blockage, traveling at speed would offer more air flow to compensate. Around town / stop n' go with a partial blockage with low air flow and less circulation your result is overheating. Not a radiator issue. If it is air entrapment, proper bleeding of the system should solve the issue.The oil should be between the two marks. If it is below, its amount is insufficient. Pour some oil into the car. Make sure it is between the marks. Check the engine for any leaks and traces of oil sipping out. In case you think your pump causes the engine overheating, examine the area around it: there should be no signs of coolant sipping out.2734 posts · Joined 2009. #2 · Dec 3, 2009.

That said, car batteries can explode at lower temperatures if exposed to them for a long enough period. Car battery temperatures higher than normal cause the inner plates/chambers to bend, which can lead to an explosion.Air gets into the system to replace the coolant volume that spilled out when you changed the t-stat, and the air blocks the flow of coolant through the system. That results in the heater core not having any heat and preventing getting the hot coolant from getting from the engine block to the radiator where it could get cooled properly. No vent ...The car is an Oldsmobile Intrigue, 2000 with 125,000 miles. The problem is with cyclical overheating. It started after the water pump was replaced.

Low coolant level. One of the primary reasons for engine overheating in Traverse is a low level of coolant or antifreeze in the cooling system. Coolant plays a critical role in regulating the engine's temperature by dissipating heat. When the coolant level is low, there is not enough fluid to absorb and transfer heat away from the engine.Just seemed so obvious it was a thermostat. Bought a new thermostat for $115!! and was a PIA to change, followed the procedure for bleeding the air out.
