first make sure you have coolant in your radiator, and if theres coolant and its still not working check your thermostat it may be stuck shut and not letting water into the engine
Bad Blend door in heating system
The radiator cap when bad will allow pressure to go back to the overflow bottle, after that check your thermostat. The coolant system should be pressurized when warm, so much so that the hoses feel hard when squeezed. The radiator cap is made to release the pressure when it becomes too great, if your cap is worn out the pressure will release too early and pressure will blow out to the coolant bottle.
Sounds like it is low on coolant.
Either a cracked head or o-rings on injectors.
Low coolant? Bad thermostat? Heater core plugged, restricted or airbound? Bad heater control? Water pump not circulating coolant?
The air in the bottle creates a noise.
Low coolant? Thermostat not opening? Heater core restricted or plugged? Heater core airbound? Water pump not circulating coolant? Temperature control not working?
It sounds like a jalopy, or it sounds fine. But, you will probably lose coolant throughout the engine and the coolant will mix with the engine oil. Your low coolant light will probably come on a few times a week.
You shoot it
heater will not blow on a 1996 ford contour
if its winter first check coolant lenvel and check coolant system for leaks. then check thermostat
no heat ford f 150 4.6 no heat ford f 150 4.6 Check the coolant level in the radiator first (NEVER OPEN HOT) most of the time it 's the coolant level being low that causes the heater to not blow hot...
I had my 2000 blow a gasket on the coolant crossover tube (aluminum) The cause of it blowing, I determined was an overpressurizing of the cooling system/ caused by a failed head gasket/ which was allowing compression gasses to enter the cooling sys, and blow excess psi off the overflow bottle. The combination of coolant blowing off the bottle, and from the crossover tube gasket, caused cooolant to accumulate in some of the plug wells, causing missfire, - Initially thought my coils were going. Smell your coolant bottle, do you smell exhaust (compression) gases? I did. Had it fix 6 months ago, and no more troubles
you increase the pressure
Could be a number of reasons for this condition. I would check the coolant level. A low coolant level could cause your heater to blow cold air when the engine is warm. Is the engine warm? If the engine is fluctuating temp it could be a faulty thermostat. Hope this helps.
Low coolant, bad coolant, blockage in the coolant line, bad heater core or element, bad thermostat
throw a stone to it :)
If it is an internal leak the coolant will end up in the crank case mixed with your oil and it will ruin the bearing/engine - if external leak then the engine will overheat when it runs low on coolant, and blow your head gasket
When we blow the aire increases in that are and the air pressure decreases forcing the thinks to move
Very likely you have a blown head gasket. Condensation is a possibility, but this sounds new. There are commercially available head gasket testers. Check your coolant level and oil condition. Low coolant indicates a leak that you can't see aka steam.
it could be that you've put too much coolant to percentage of water in
use an air compressor hose with a nozzle designed to blow the air on it, or a can of compressed air.
Because air takes up space. When you attempt to blow up the balloon, you are adding air to the inside of it. But the air between the balloon and the bottle has no place to go. It will only contract so much.
