There is no reason to ever bleed a cooling system.
The cooling system of a BMW 318i is bled by opening the radiator cap and squeezing the upper radiator hose. This purges air from the system which can then be replaced with more coolant.
If a head gasket is bad, the pressure of combustion can be transferred into the cooling system. The addition pressure in the cooling system can blow out the radiator. Assuming your not replacing it with a used one. Used radiators are usually temporary.
The cooling system.
you might want to check for a blown head gasket or a cracked head or block. espically if it loosing water out of the radiator with out leaking on the ground.
The radiator is part if the cooling system.
Motor cooling system? The engine cooling system consits of the water pump, radiator, hoses, cooling fans, etc.Motor cooling system? The engine cooling system consits of the water pump, radiator, hoses, cooling fans, etc.
Air in the system. Bleed the cooling system and remove any trapped air pockets.
Low coolant? Cooling fan not working? Radiator plugged or restricted? Water pump not circulating coolant? System air bound? Defective radiator cap?
Rust and sediment can accumulate in the cooling system. Flushing the radiator helps keep the cooling system clean.
you may have trapped air in the cooling system..try bleeding the cooling system
The radiator cap controls cooling system pressure.The radiator cap controls cooling system pressure.
Once the cooling system has had time to depressurize, open the radiator cap and pour your coolant in.
The cooling system
Sometomes it is hard to get all of the oil out of the cooling system. However the place that replaced the engine should flush the cooling system until it is clean. Also if your car has an engine oil cooler , it could be the cooler in the radiator and not have been the engine in the first place.
There is a leak somewhere in the cooling system. Have the cooling system pressure tested for leaks.
If you do not have a radiator cap once you drain the radiator, you can use several options to flush the cooling system. You can easily do this by filling up the system with as much water as you can and then warm it up.Ê
cooling system needs flushed out and a new thermostat installed, also if the radiator is still original it probably needs replaced or rodded out.
Cooling system leak or engine overheating and steam escaping from the radiator cap.Cooling system leak or engine overheating and steam escaping from the radiator cap.
Low coolant? Cooling fan not working? Bad thermostat? Cooling system airbound? Water pump not circulating coolant? Radiator core plugged or restricted? Bad radiator cap?
There may not be one, My 2000 Lumina has a plug on the lower drivers side of the radiator that can be replaced with a petcock. Rather than do this I removed the lower radiator hose to facilitate flushing the cooling system.
IF IT WAS NOT OVERHEATING BEFORE THE HOSE WAS REPLACED -- MORE THAN LIKELY YOU HAVE AIR POCKETS TRAPPED IN YOUR COOLING SYSTEM
Could be a collapsed lower radiator hose, perhaps a bad thermostat.
