After replacing the thermostat, you must bleed the air from the cooling system.

To bleed air from the 2.2L and 2.5L engines, remove the plug or sensor on the top of the thermostat housing. Fill the radiator with coolant until the coolant comes out the hole. Since the plug is made out of steel and the thermostat housing is aluminum, it is a good idea to apply an anti-seizing compound or Teflon® tape on the plug threads prior to installation. Install the plug and continue to fill the radiator. This will vent all trapped air from the engine.

Any trapped air in the heating system will have to be displaced by coolant. Once the cooling system is filled, with the radiator cap off, turn of the heater at it's highest setting. Start the engine and allow it to reach operating temp. You should see a drop in the coolant level as the air in the heating system is displaced by coolant. Add coolant to the proper level and replace the radiator cap.

Keep a close eye on the coolant level for at least the next couple of weeks. The cooling system is a "closed" system. Any significant decrease in coolant level indicates a problem.

If you have any questions, let me know.

Drive safe and be warm.

if the heater core is getting hot then the problem is the air temp control blend door actuator, a common problem.

Trans temp high


start by cleaning your radiator cooling fins first and have the core checked, if in order start by replacing all filters, drain the oil ,flush the whole system with approved atf oil, oem, fill ,test transmission , keep hand brake on, engage drive selection then reverse, the switch off and check oil level. if dropped fill up but do not over fill for it can cause heating, drain if needed. once all completed that a drive and test, if still heating up have the torque converter tested. Normally it's either too much oil or too little/oil lost it's viscosity through over heating

2007 montana - low rpm - under 1k - no heat.


Make sure you radiator is full. There are 2 bleeder screws for that engine because its really hard to get all the air out. If its low or has too much air in it, you won't have any heat at low rpms.

Second thing is that your heater core may be a little stopped up and needs flushed, or replaced.

Thirdly, i've noticed that the Montanas don't put out a lot of heat if you're setting. But you should have some heat to keep you warm. No heat is no good.

Its over heating and ive changed the water pump clutch fan and themostat.


You may have a blown head gasket. They can leak outside the motor, inside the cylinders (causues white smoke), or into the block causing water in the oil (light brown color and or bubbles on the dipstick) or oil in the radiator. Hopefully you have none of those, so the next step is a radiator flush as you probably have something clogging up the radiator or thermostat. You have to drain the radiator and fill with clean water. Pull out the thermostat and leave it out for the flush. There are radiator flush products that I suggest highly. Run the truck to operating temp (about 20 min) with the heat on and dump the system by removing the bottom hose hose from the radiator, after the truck cools off. With the hose still off dump water through the radiator to clean it out fully. fill with water and let it run once again to clean the block, then reinstall new thermostat and anti-freeze. This should clean out any rust and stop leak that is causing your problems.

What could be the reason for over heating? give me some parts i should look at


Possible reasons of over heating include, low water, thermostat, no thermostat installed, radiator stopped up inside with gunk or outside with bugs, broken or missing radiator shroud, missing lower air dam, fan not running if electric or fan not running because of oil filled fan clutch, intake gasket or gaskets stopped up, blown head gasket, cracked head, cracked block. I put these in order of simple to hard and mostly low price to high price. Hope this helps.

Grand vitara radiator over heating


I have had brand new Thermostats that are bad. The way to check a thermostat is to boil it in water and see when it opens. You may need to have your radiator cleaned or roded out. You can also remove your thermostat and see what happens then I would start by flushing the system and see what you get.

1984 Olds Delta 88 307 over heats.


If you have an automatic transmission that is routed through your cooling system, and you've tried everything possible to correct overheating, your tranny may be on its way out. The problems your tranny may be having having operating normally could be effecting the engine temp.
THE other problem may be that you just need to replace your radiator cap. If that fails then check your fan to make sure that they are working. if that fails that it could be a bad head gasket and it needs to be replaced

1997 sl2 inside heater barely heats


What temp thermostat did U put in????? Check and see what thw manufacture call for you car. Also check to see if any leaves are in your heater box, which is stopping the air flow. Some cars have and air filter on the inlet duct. It could be plugged. Check this out also.
Take the 2-heater hose off where the water goes into the heater coil. Back flush it with your home water hose, the oopposive direction that it normal goes. It can get stop-up. You can also flush your whole system by empting the radiator and put a can of old time comet into the radiator, and fill it also with water, let it run for 1-hour, the empty a,d fill with water 2 more times. Fill it back with antifreeze and go with it. This should clean everthing.
