Coolant level keeps getting very low?


Check the upper intake gasket, you may have a leaking gasket. Check the bottom of water pump and see if it is leaking, if so pump needs replaced. The seal within the water pump sometimes goes bad and leaks out seep hole on water pump bottom. Make these checks with engine off!!! God-Bless!

Overheating issue


The big question is it overheating because of coolant loss (a leak or leaks) or is the overheating caused by a jammed thermostat, blocked radiator or the cooling fan not working.
This is the confusing chicken-and-egg situation that often faces the diagnostician, especially as when checked the coolant level is likely to be low in both cases and overheating can create coolant leaks...
Furthermore when an older engine overheats a lot or boils it can begin a chain of events that causes great expense and inconvenience over an extended period of time...

In your case it would seem the coolant is low because of a leak and that is what caused the overheating. Clearly you need to trace the leak and I can be of little help in the matter other than to suggest a hose can fail at any time and although regular inspections can greatly reduce the chances it can't entirely eliminate the possibility. Water pumps on the other hand, often aren't accessible for inspection without removing lots of stuff but they are generally very reliable and tend not to suddenly start gushing coolant. Most often they are responsible for a minor mystery coolant loss that gradually gets worse over an extended period.

I am wondering if the previous owner could have known something about the problem.

Locating the leak would generally mean getting under the car and removing any undershield components in order to narrow the area of the leak and then remove any further components until eyes can be rested on the actual source of the leak.

Temperature rise


Because the heater is getting cold, that indicates low coolant. It leaked out and the leak needs fixing, but as soon as the engine cools off, refill the coolant and keep it full. Never add coolant to a hot engine without the engine running. Your electric fan might not be working. The fan moved air through the radiator and air circulated the same way when the car is moving. Check that.

If you can see your water pump, feel around the neck of it for moisture. Any moisture there means the pump leaks and needs replacing. Some cars have the water pump behind the cam belt. You can't get to it without a lot of hard work- get that done by a qualified mechanic if you can't find your leak elsewhere, such as a leaking hose or bad radiator cap.

If your electric fan doesn't work, that might be the whole problem. Usually the fan relay fails before the actual fan. Replacing the relay will solve the problem if that's it. Good luck. China OBD2 car diagnostic tools wholesale on CareUCar

My low coolant light came on on my 2000 gmc sierra pickup so I filled the resuvior know um leaking antifreeze some where and my belt is squeaking any suggestion


Check the water pump for signs of leakage.If this isn't the cause, then perform a pressure test on the system. This will allow it to leak without running the engine and make it easier to source the leak.

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.

My low fluid light is on, my heat is not working properly, i have fluid leaking under my car not really sure what it is. i know it is not oil, or tranny fluid, think maybe water and coolant, but my coolant...


Low fluid light means check your coolant which prob whats on the ground. Depending on the rate of leakage fill coolant start try and locate leak sounds like a hose or water pump slow leak prob water pump fast leak hose good luck

Water running out at rear of motor


It could be a bad cooling or heater hose.
Don't let the level of coolant get to low, and toast the motor.
Could be an easy fix, but you need to get a mechanic to check it out.
If taking pressure of the system by unlatching the radiator cap a notch
to take the pressure of the system, may help slow down the leak
and let you drive it without leaking, but in hot weather it would cause an overheat problem.

My 1997 Plymouth Voyager mini van 2.4 liter van is leaking the water on the outside of the van in the front passenger side. Can't find the leak. It leaks when I'm parked and when I'm driving.


well it can only come from the radiator hoses or the water pump...

to check if your water pump is still good just take a flashlight and spot on top of the pump. there should be a little hole on top behind the pulley. if it is damp you have to replace the pump.

besides that just check the hoses one at the time
