There is a screw cap on the hose for the interior radiator you can see them when you open the hood in the center of the car under the wipes. Fill up the coolant start the engine turn the heating on max unscrew the cap and let it open till you can`t see any air coming out of it then close it and turn the engine off. CARE THE WATER WILL HEAT FAST SO WEAR GLOVES..........

AS a owner of a 2007 pontiac torrent I am having trouble with no heat could you help me with this problem?

Air lock in the engine cooling system, likely from a bad water pump or other small leak allowing air into the system. Look for wet spot at bottom of water pump an indicator it is bad. Open radiator cap or reservoir and pump the hoses by hand to remove the air by squeezing it out rapidly or rev the engine up and down to assist air out of system with the caps off the reservoir or radiator. keep filling it up until there is heat and it doesnt flow out of the rad.

Replacing antifreeze on a suzuki grand vitara 1.9 diesel 2009 model how is it done

Almost every car is the same. There will be a valve on the bottom of your radiator, if not (rare) you will have to take the bottom hose off. It is almost impossible to get all the old water out of an engine, so some people use a flush kit to run water through the system to get it clean. Then you will want to refill with a 50/50 water antifreeze solution. You have to keep in mind that if you flushed it with water then there will be a certain amount of water already in it. Thus add more antifreeze than water to make up for this. Also it is best to refill with distilled water to avoid any minerals that may be in your water supply. Make sure there are no air locks and top up after running the vehicle and allowing it to cool down.

if the thermostat is in the head at the top radiator hose , remove it an fill the cooling system until the water is at that point --refit the thermostat and continue filling
make sure that the heater is turned on so that any air is moved out of the system

Engine overheating i have replaced the radiator has plenty of water

replace thermostat.then bleed coolant system, this is how you do it.fill the cooling coolant system with 50 / 50 dexcool and water to raise boiling point,straight water will evaporate boil away cause engine to overheat catch fire thats why you need 50 / 50 mixture antifreeze and bleed coolant system first fill coolant system until coolant stay at the full cold mark on the the coolant overflow jug,then you start engine allow it to idle,place the heater and ac control in any ac setting except max and the temperature control to the highest setting,run engine until lower hose to water pump is hot. with the engine hot run the engine speed up to 3000 rpm and allow it return to idle, repeat this 5 times. slowly open the bleed valve on the thermostat housing or look for bleed valve at the water pump heater bleed valve for 15 seconds to expel any trapped air.then top off the coolant as necessary,and when top radiator hose hot thermostat open up.keep adding cooling to overflow until coolant level stop at full cold mark dont over fill coolant.if engine seem like overheating while looking at cooling gauge turn off engine wait a while until cool off add more coolant until coolant level stay stable and dont drop any.when open radiator overflow cap use large rag over the radiator cap to keep from getting scald open radiator cap a little at a time but dont open radiator cap until engine cool down first.replace the radiator overflow cap, thermostat,and engine coolant temperature sensor and check the cooling fans fuses and relays see what happens.

Over heating, replaced thermostat, still over heats, i have a 2004 dodge stratus, 2.4L DHOC

After changing the thermostat, did you fill it with 50/50 antifreeze to water?

Is the radiator cap (not actually on the radiator) in good shape and seating properly?

If the answer is yes to all of the this, than I would try picking up some heavy duty flush from the local parts store and flush the system really well.

Hope this helps.

My collant level warning say is low so i added more collant so how come the check engine lights still on?

check that the radiator is full to the top... sometimes there is a small air lock in the top of the radiator, take off the radiator cap slowly and fill it up till it overflows a little and replace the cap letting as little air as possible into the system, hopefully the light will go out. Otherwise it could be an airlock elsewhere in the system, squeeze all the pipes while the engine idles and move the water around by squeezing in a rhythm, you will feel the difference between an air filled pipe and a coolant filled pipe, check every bit of pipe is full of water with no air locks in bends or twists.

I replaced the water pump and thermostat in my sons 1998 Jeep. It has a 4.0L and the water pump out let hose back into the radiator sits several inches higher than the radiator. This is causing a air lock....

4.0 engines aren't really prone to air locks. Keep the heater on high while re-filling. If you have an overheating problem and you can't get the radiator to fill fast enough, likely the radiator core is internally blocked. When that happens it seems that the upper hose can't be purged of air. Jeep radiators are in my opinion too small for the engine and if partially blocked, have no "leeway" or forgiveness. They just will not fill correctly.

1997 bmw z3 conv. 1.9 overheated, changed radiator, new thermostat, hoses car still overheating , fill radiator w/water but water does not seen to go through , released air pressure from radiator and...

hi jasso, I would recommend checking the water pump if you see no flow in the radiator. Make sure when you fill up the cooling system, that you fill it cold, and that the vent screw in the radiator is loose. fill system until fluid comes out the vent screw. tighten the screw, start the car and have someone run at 1500rpm and check for flow.also, make sure that you have your temp setting full hot and blower on middle speed so that you don't trap air in the heater core.

Coolant filling up overflow bottle and not returning Started intermittently No coolant leaks Changed Hoses Cap Thermostat Cooling system has always had good quality coolant and is clean inside...

You may need to ask AAA to put a radiator pressure tester on the resevoir bottle and pump it up to operating pressure(Pressure cap rating) and see if it over pressurises while it is running at operating temp,rev engine up and down and watch what the testers pressure readings do,it should move up and down in sync with the water pump.If the pressure keeps building i would have to believe that combustion chamber gases are over pressurising your cooling system.Also test the pressure cap is functioning within factory specs.
