When changed air was introduced to the system theres two little nozzles you have to open up and turn your car on to release the air. Let it go till coolant is constantly squirting out of both of those holes then while its still squirting out close them problem solved. It is also possible that the reservoir was too full to begin with. Most coolant reservoirs have a minimum and maximum fluid level which should be maintained. Too much fluid will cause overflow and too little fluid can cause the radiator to operate at less then 100% efficiency.
If a lower radiator hose was replaced on a 1999 Dodge Grand Caravan, but it is still leaking fluid, it could be that there is a hole in the radiator. It could also mean that there is damage to the overflow reservoir or its hoses.
It sounds like you might have a crack in your radiator or reservoir and will need to get it repaired or replaced.
You need to check coolant temperature sensor and the water pump.
if the coolant in the overflow rises and overspills when you shut the car off or is boiling in the reservoir
Just check your overflow container after a few days, if there is any air in the system it should work it's way out and just bubble in the overflow tank. If you see the tank level drop and you don't have any leaks, then there was some air. It is not a major concern.
check radiator for small leaks or cooling lines which would most definitely cause it 2 steam when running after awhile
likely possibilities are the following. Low or bad coolant , water pump, thermostat needs changing, clogged radiator or lines, coolant temperature sensor or radiator fans not coming on, head gasket Also check the radiator caps on the hose and the overflow container. That was my problem. One or both may have to be replaced.
If your heater core wasn't leaking at the time your radiator was replaced , then ( no ) That would be two separate jobs
It sounds like you have a blown head gasket. Combustion gases can enter the cooling system through either a blown head gasket or cracked cylinder head. The gases (under pressure) force coolant out of the reservoir. This also causes a void in the upper part of the cooling system , leaving no coolant at the thermostat and the coolant temperature sending unit. The result is a erroneous temperature Reading and will even prevent the thermostat from opening.
An overflow pipe on a (toilet cistern?) will leak if the rubber disc in the ballcock slide valve needs to be replaced.
the filter is built into the power steering reservoir . the filter cant be replaced separately . the reservoir itself should be replaced.
The radiator will need to be replaced. Sometimes, it may seem that the radiator itself is leaking but it could be the radiator "hose" that is leaking. In this case, the radiator hose needs to be replaced and clamped tightly.
