Why would i be going through so much coolant without a leak


Check your oil. There probably is coolant in it from a head leak. Also look at the exhaust . Should not be white and smoky. There is a leak somewhere.

2003 lincoln aviator water boiling and car overheating


Check to coolant level after it cools off and check to see if coolant-water mixture is correct. If those are ok. You could have to much air in the coolant system. Most radiator caps will automatically vent the air out of the coolant system. It could be as simple as a coolant cap that gone bad. Or you may have a air bleed valve on it and you need to bleed the air out manually. To bleed it you will have to crank engine and get it warm. Touch top radiator hose to see if its warm. If not then the thermostat has not opened yet. That could also be the problem. After it gets warm open the bleeder valve if equipped and bleed all the air out. Once the steam and hot air from the valve starts to be gone and pure coolant coming from the valve. You have successfully bleed the coolant system. Cool engine back off and check coolant level once more. Hope this helps.

Hi,
If you are not seeing any leaks, most likely air in the coolant system, improper/weak coolant mixture, bad radiator cap, bad thermostat. Sounds more like the air and/or weak coolant to me.

I OWN A VOLKSWAGEN PASSAT, JUST BOUGHT IT NOW THE HEAT BOLWS OUT COLD AIR WHAT SHOULD i CHECK OR DO


Check operation of the heater coolant on/off control valve and operating mechanism.
Check thermostat is installed and working OK - replace if in doubt.
Check if coolant heater supply hoses are warm/hot when coolant valve on.
If hoses are cold (no coolant flow evident) check coolant system is properly filled (bleed system as necessary to remove possible air locks).
If still no coolant flow check heater system for blockage.
If all above ok, check heater unit air control vanes operation.

Blower working but dont have no heat i changed the thermostat still not working im hoping its not heating core any suggestions


if the cooling system is not clogged and the water pump is ok then there may be air trapped in system, bleed air from system if need be. if air is trapped in system you will not get any heat. start car let it run take cap off of coolant tank then find bleeder for the coolant system, open bleed screw and air may be trapped in system.make sure coolant is at a proper level. do not forget coolant tank cap when done.

No heat changed thermostat flushed engine new coolant


did you release air from cooling system when replacing coolant!! if air is trapped in system it will not heat up proper. turn fan on high heat locate bleeder for cooling system, open bleeder with car running. if there is any air in system you will see it come out of bleeder. keep checking for heat. when you get heat bring coolant to proper level. leave top off of coolant recovery tank while bleeding system. put cap back on when done.

Where do i refill coolant? message reading low engine coolant.


please rate, thx Coolant Recovery System NOTE: When the water thermostat (8575) is closed, there is no flow through the radiator coolant recovery reservoir (8A080).

Trapped air in the cooling system must be removed. A pressurized radiator coolant recovery reservoir system is used which continuously separates the air from the cooling system.
  • When the water thermostat is open, coolant flows through the small hose from the top of the radiator outlet tank to the radiator coolant recovery reservoir.
  • The radiator coolant recovery reservoir separates any trapped air from the coolant and replenishes the system through its radiator coolant recovery hose to the water thermostat housing.
  • The radiator coolant recovery reservoir serves as the location for:
    • service fill
    • coolant expansion during warm-up
    • system pressurization from the pressure relief cap and
    • air separation during operation
  • The radiator coolant recovery reservoir is designed to have approximately 0.5-1 liter (0.53-1.06 quarts) of air when cold to allow for coolant expansion.

sounds like hoses going to heater core but they are rubber usually. But it could be the hoses for the degs bottle mounted on the passenger side inner fender.

Coolant Recovery System NOTE: When the water thermostat (8575) is closed, coolant flows through the degas tube and hose assembly from the lower intake manifold to the radiator coolant recovery reservoir (8A080) .

Trapped air in the cooling system must be removed. A pressurized radiant coolant recovery reservoir system is used which continuously separates the air from the cooling system.
  • When the water thermostat is open, coolant flows through both the small hose from the top of the radiator outlet tank and the degas tube and hose assembly from the engine to the radiator coolant recovery reservoir.
  • The radiator coolant recovery reservoir separates any trapped air from the coolant and replenishes the system through its radiator coolant recovery hose.
  • The radiator coolant recovery reservoir serves as the location for:
    • service fill.
    • coolant expansion during warm-up.
    • system pressurization from the pressure relief cap.
