What else can I help you with?
What could cause coolant to overflow even though engine temperature is normal on a cool day and no coolant was added?
The engine needs to be flushed.the coolant ports have a build up of gunk causing the engine to run hotter. The heated water expands to much causing it to over flow from the reserve tank.
What happens if engine coolant is put in while the car is off?
After coolant is added run vehicle to normal operating temperature and re-check coolant level
How do you know when your head gasket has gone?
White smoke from tailpipe when engine is at normal operating temperature? Oil mixing with coolant? Coolant mixing with oil? Run engine to normal operating temperature remove dipstick and let a drop fall on hot part of engine - oil will smoke coolant will "sizzle" Misfire at 2 adjacient cylinders?
Is it normal for smoke to pour out of the overflow hose connected to the coolant reservoir?
this sounds like a bad thing to me...like the reservoir and/or the cooling system, has no antifreeze in it and heat from the engine is exiting through the cooling system. Does your temperature gauge read in the normal range? Is the car running OK? FriPilot
How do you get the low coolant light to go off on a 2000 Buick Century with levels fine in radiator and overflow and temperature gauge only one mark above normal?
You may have a faulty coolant level sensor
What is the normal coolant temperature in a Cadillac?
Depending on the engine, the coolant temperature in a Cadillac could be from 180 to 195 degrees. The thermostat can be changed to give a lower or higher temp reading.

Engine misfire from 2 adjacient cylinders?
What is the normal operating temperature for a 1999 suburban 5.7?
I am an ASE certified technician. Your normal engine or coolant temp should be 190 - 210.
How does a fan switch work in a car?
The fan only runs when needed to help cool the engine. The engine coolant sensor or a separate engine temperature switch is used to monitor engine temperature. Extra cooling is not needed when an engine is first started, so the fan does not come on until that engine reaches normal operating temperature which is usually from 195 to 215°F. The fan will then cycle on and off as needed to maintain the coolant temperature. So the fan runs mostly at idle or low-speed when the engine is at normal picture.
How do you tell if a header gasket is blown?
Oil in coolant? Coolant in oil? Excessive white smoke from tailpipe when vehicle is at normal operating temperature? Engine miss or skip?
