1) Defective water pump 2) Stuck thermostat 3) Broken positioning tab inside thermostat housing (located at engine block on front side under AC compressor, if you have AC).
Either coolant is low or the sensor in the reservoir is stuck with dirt. Clean the reservoir with soap and water
First check the coolant level, a coolant leak would cause a heater to stop working- assuming you mean the blower is blowing but it isn't hot. A stuck thermostat will also cause you problems with your heat.
I think you may be referring to coolant leaking from engine? engine coolant or water can leak from any coolant hose or heater hose, waterpump, thermostat housing etc, wurse case the head gasket is leaking coolant externally, need a pro to check it out
Yes it can. A faulty thermostat can cause overheating which will cause coolant to be pushed out of the system.
No, low coolant would cause the opposite.
a leak in a head gasket could cause coolant to go into only one cylinder.
broken radiator
cause it would probalby be cool
water pump, oil, water, engine coolant....main cause would be engine coolant, just check to see if you have a leak.
crack in engine block or head, so the coolant leaks through crack into oil. very common problems with engine to get cracks, maybe a design flaw or when you ran without coolant, it may overstress engine!
The coolant capacity for a 2004 Saturn Vue with a 2.2L engine is approximately 7.6 quarts. It is important to use the recommended coolant type and mix it with distilled water in the correct ratio for optimal performance. Overfilling or underfilling the coolant system can lead to overheating and potential engine damage.
