What would cause the engine to die when the temperature goes slightly past normal operating temperature on a 1998 Pont Gran Am SE v6?
I know alot of people with Grand Am's and they are all a piece of junk. Everyone that owns one that I know, which is about 10 different owners, say they are constantly having problems with their Grand Am, and would never recommend one to a friend, but they would recommend it to an enemy. lol. Everything seems to go wrong, but mostly it's the engine components(the most costly) that break. Trade it in asap.
Best way to tell your normal operating temperature is to visit an auto parts store and ask them what the OEM thermostat temperature is (or you can look it up yourself on Autozone.com). Most cars these days will have around a 190 degree thermostat. Your car will run slightly hotter than that temperature as it is needed to maintain the thermostat in an open position. With that thermostat you can expect to see the temperature…
That can vary per vehicle, it could be around 227 degrees However, remember that water boils at 212 degrees. The boiling point of automotive coolant varies slightly from that, but the system is pressurized, so boiling is "normally" not a problem. Most modern, fuel-injected automobiles have a normal operating temperature of 190 to 195 degrees. Older cars operated at about 180 degrees.
Oil mixing with coolant? Coolant mixing with oil? Run engine to normal operating temperature, remove oil dipstick and let a drop fall on hot part of engine - oil will smoke coolant will "sizzle" White smoke from tail pipe when engine is at normal operating temperature? Engine misfire from 2 adjacient cylinders?
Or, if everything else is operating properly, it could be the thermostat or a blocked radiator, but I'd focus on the thermostat first. Be certain that the engine is at normal operating temperature when looking to see if coolant is circulating. A properly operating thermostat will prevent the circulation of coolant while engine temperatures are below operating temperature.
A thermostat is a temperature sensitive device used in a vehicle's cooling system to control the flow of coolant between the engine block and radiator. A thermostat is important for several reasons. 1. It helps allow the engine to operate at optimal fuel efficiency. 2. It allows the engine to reach optimum operating temperature quickly. When the engine is cold, the thermostat stays closed, allowing the engine to reach operating temperature quickly. Once the engine…
The 4.2 L 6-cylinder engine uses a 195* thermostat per the factory specifications. The thermostat begins to open at 195* and is fully opened by about 200*. 200-215* as shown by your dash board temperature gauge is considered normal operating temperature if your cooling system is in good condition and properly maintained.
