Where do I start to look at when engine overheats when air conditioner is on


The A/C causes the engine to work harder (that's why fuel economy suffers when it is run).

If your car has an electric fan - make sure it runs when the engine is hot. If it does not - you may have trouble w/o the A/C running if is gets warmer outside. Look for fail fuses, disconnected plugs, etc.

You may also have flaky thermostat that is not opening fully when needed to exchange hot water in the engine block with cooler water in the radiator.

First, check the coolant level. You should find a semi-transparent reservoir / tank located under the hood that has a cap marked "Coolant". The side of the tank should have two indicator lines - one for HOT and one for COLD. If the engine has been run up to normal temperature (so that it can provide heat in the car), you should see the coolant level at or slightly above the HOT line. If the engine is cold - first thing in the morning or after sitting for several hours - the coolant should be at or slightly above the COLD line. View these levels while the engine is off and the car is parked on a flat, level surface. If there is not enough coolant - you will need to add the CORRECT type for your car.

Hot Engine
(1) With the engine hot, add enough coolant to the tank to bring the level to the HOT line. You may have to check the tank several times after driving if the coolant level in the radiator is down a great deal. NEVER open the radiator cap when the engine is warm or hot!

or:
Cold Engine
(2) With the engine cold, add enough coolant to the tank to bring the level to reach COLD line. Additionally - with the engine cold - you can add coolant directly to the radiator by removing the cap. Start the engine, set heat in car to HOT and add coolant mixture to radiator until level comes up to the bottom of the filler neck. Once the engine is HOT (getting heat in the car) check and top off radiator as needed and put cap back on radiator.

Check the levels in the TANK several times over the next few days when cold. If the tank ever empties -you'll need to have this looked at by a mechanic.

Could be a faulty thermostat, low coolant, or a faulty blend door under the dash.

Cooling system


Raise the car front end as high as possible with a floor jack, fill the coolant tank to the top, run the engine until it reaches just short of overheating, shut it down and run water over the radiator, this will burp the air out. Repeat as needed. Don't let the coolant recovery tank run dry during procedure.

My heater isnt working, the temperature gage flucuates, and it keeps telling me it has low coolant even though I just added coolant


low coolant sensor is probably just dirty. cold air could also indicate n air bubble in the line. could also be thermostat. try that first.

When my car need coolant do I have to add it to the coolant recovery tank and the radiator


Both, I recomend you add the coolant to the radiator untill it tops off, with the car on, and then add to the recovery tank untill the fill line. NOTE: ensure the engine is not hot before removing the radiator cap, if it was running let it cool for a while before opening it and if you add cold coolant to a very hot engine the engine block can crack.

Adding Coolant


Wait til the car is cold and then open the cap on the RADIATOR by pushing it down while twisting. The coolant must be filled to the brim. Replace the cap and then fill the overflow tank to the "cold" mark. Use a 50/50 mixture of water and coolant.
