Make sure u have no air pockets in ur coolant system.Remove the overflow cap and let the engine run for awhile and rev the motor a bit to make sure it heats up faster. U should see air bubbles in ur overflow bowl. Do this until no bubbles come out. Could take 30 mins and be careful cause the coolant could splash upwards, a good 2-3 inches above the bowl. Just make sure when ur done u rinse under the wood really well with a garden hose.

Hope this helps.

Replaced the radiator, heater core and thermostat and car still wont heat up...my car is a 94 mercury tracer stationwagon


Hi,

You've go so far but you havn't mentioned the water pump ! It's possibly 17 years old and due a rest. It's called a pump but it's mearly circulates the water provided the thermostat is open. It'll be a cheap fix compared to lifting the cyl head and head gasket replacement! You seem to have had some advice , replacing the difficult stuff (possibly from the supplier of a rad and heater matrix core??? ) If the car is running there is heat somewhere ! check the temprature of the Rad hoses , the will be hot (caution) after a few minutes of running. then check the two smaller hoses going thru the bulkhead (into heater matrix) and both sould be equally hot under normal conditions. If not .... pump replacement is a worthy option.

1995 BMW 525I over heating issue. I repaired head


Hi, Sounds like you have tried about everything. Ok the aux. coolant switch is for the electric pump for the heater core will not cause an over heating condition just a longer warm up of the heater core. Has the cooling system been bleed properly if there is a trapped air pocket it will not let coolant circulate. Was the new thermostat installed correctly? They have a vent that needs to be towards the top or they trap air on the back side and cant take an accurate reading to open and close. Other areas to look at would be proper operation of the fan clutch, if they fail they can cause the fan to not lock up properly and supply enough air movement through the radiator. The aux. electric fans and their temp switches do you hear them coming on are they coming on at the right temp.

99 jeep cherokee problem w/ heat I replaced the blower motor, water pump,radiator, thermostat and flushed the coolent system. Still getting little heat. I'm thinking heater core or head gasket... Is there...


It sounds like the heater coil needs flushing out or replacing or the heater valve. Look on the engine firewall and make sure the heater valve is opening. If not open it manually and check the heat level. If that produced heat check the condition of the heater vale cable (or vaccum hose).

It could be the water pump, radiator, or cooling fan not working properly. If your heat is off it will not be the heater core.

Overheating - Not holding water


Check your engine oil. If there is fluid in it (radiator fluid)....bad.

Do you have smoke...white (not billowing, but like it disappears)....from the exhaust?....bad....

Head gasket is bad.
