Pressure test the cooling system, then fix what that shows.

My 97 cadillac deville over heated 1 time on the highway. after filling it with coolant i dont have any problems. why did it overheat that 1 time


if you are using coolant that is mixed 50-50 with water, the water will evaporate. If you are having issues and using straight antifreeze without a water mixture, you may have a small coolant leak or a small leak in the head gasket.

After many miles the coolent temp light is on


The coolant light tells you are low of coolant, so have you checked to make sure that you have enough coolant - between the two marks on the radiator overflow reservoir? If not add and then keep a close eye on the ground under your car for the next few days to make sure that you are not leaking any out.

And if you haven't replaced your pressure cap on your radiator in several years, you might want to consider that.

1997 Mazda 626 (2.0 liter): The check engine or malfunction light came on and will not go off. Since this light came on, the heater/defrost will not blow warm air. Temp guage shows hot after car has been...


sounds like the head or head gasket is blown. your cylinders may be getting coolant in them which will not only cause the motor to lockup, but also cause bent rods and valves. check your oil dipstick and transmission dipstick to see if it looks like water or coolant is presant, also check the coolant to see if it smells like gas or has any kind of oil in it, if so, your head is likely blown.

Hoses to cooling system keeps bursting


I agree with the questions asked by c17hydro, but also keep in mind that if the new coolant hoses are springing new leaks in the body of the hoses (not at the connecting points), this would be due to excessive PSI build-up in the hoses and you may have a much larger problem. After the car has sat and cooled overnight, start the car with the hood up. IF after 3-5 minutes of idling, the coolant hoses build up pressure immediately (hoses are very firm), this may be due to exhaust fumes entering the cooling system, which is an indication you have blown a head gasket or cracked the cylinder head. Your car will still run, but it's performance will be very poor and sluggish.

Coolant temp. raising. no coolant loss.


first with the car off and cool squeeze bottom radiator hose with your hand then do the top,this burps any air out of the system,of course have the cap open,if this doesnt solve the problem its your radiator cores are block as you speed up its trying to force coolant thru a blocked core and temperature rises,you can pull your raidiator and have it cored at a radiator shop,cheeper than buying new
