DEPENDS TO THE AIR CON NEEDS TO COOL DOWN. AS EVERYTHING IS UNDER PRESSURE.

Posted on Apr 22, 2014

Testimonial: "I don't understand that sentence. I am getting the same amount of cooling, very little, with 3 cans of coolant as I did with 1. I am being told it just needs more coolant but logically, it should not be that empty, since it has nowhere to go, unless there is a leak. Correct?"

    mrs HAKE ,starting again because I have your reply and you confused me. The cooling you need as I understand is for your engine radiator and not the Air conditioning. If it is for your radiator and you still topping up,is true you might have a leak somewhere. Check for water pump,radiator,any hoses,or the heater (matrix )( which is under the dashboard. If is that surely you will have wet floor (carpet) either with driver,or front seat passenger. Ask for a qualified mechanic to help you because is not easy job.

    I'm sorry, the problem is not with the radiator \ engine cooling. The problem is the air conditioner, something I have little knowledge of. I do have access to a hose with a gauge and after adding 3 cans of "freon", it is still not registering on the gauge or the air coming out of the vents.

    Well, this was useless. Also, I bought the chilton for my van. Still no answer.

While running the air conditioner the Thermostat goes hot, when I turn the air conditioner off it goes back down. The low coolant light came on but the coolant is full. What else could it be?


To start with, you are talking about the temp gauge. The thermostat is in the engine.
The coolant system could be low or have air pockets and still look full.
First thing I would check is the cooling fan, then the coolant level.

I would check the IAC motor or idle air control motor, heres a little info.about the part.Stratus Sedan, 1999-2005 Idle Air Control Motor

Description & Operation

Not for Dodge Stratus Sedan
The idle air control motor (IAC) attaches to the throttle body. It is an electric stepper motor. The PCM adjusts engine idle speed through the idle air control motor to compensate for engine load, coolant temperature or barometric pressure changes. The throttle body has an air bypass passage that provides air for the engine during closed throttle idle. The idle air control motor pintle protrudes into the air bypass passage and regulates airflow through it.
The PCM adjusts engine idle speed by moving the IAC motor pintle in and out of the bypass passage. The adjustments are based on inputs the PCM receives. The inputs are from the throttle position sensor, crankshaft position sensor, coolant temperature sensor, MAP sensor, vehicle speed sensor and various switch operations (brake, park/neutral, air conditioning).

When engine rpm is above idle speed, the IAC is used for the following functions:

STEPS TO CHARGING YOUR CARS COOLING SYSTEM:

STEP 1) Look under the hood of you car on the left side of your cars engine. There should be two stainless steel lines coming from a stainless steel cylinder to your cars compressor. The two lines have plastic dust caps on them sometimes they are blue or black. Usally the black has the larger diameter tubing that runs between the evaporator and the compressor. This will be the port that you hook the refrigerant hose up to.

STEP 2) Start your cars engine after you have secured the hose hook up to the air conditioner line port. Once the cars engine is running, turn your cars AC on to Max cool. Shake the can of coolant well. The gauge on the can of coolant should read in the blue but if it is in the green your air conditioners pressure will be between 0-25 pounds per square inch. This means you will have to add refrigerant to the compressor.

If your cars air conditioner pressure is in the blue. The system has the proper amount of refrigerant and you do not need to add. If the gauge reads in the yellow you may want to seek professional help because refrigerant is not what is wrong with the unit and is probably something more technical and most likely something that you do not want to attempt to do on your own. The red on the gauge means do not add any refrigerant at all and to seek professional help.

STEP 3) If the pressure of your air conditioning system is in the green it means it is safe to add the refrigerant. You should wait for your air conditioning compressor to switch on before squeezing the trigger to add the coolant. When the compressor switches off then release the trigger and repeat until your pressure gauge on the coolant can says that the coolant is in the proper range. If the needle on the gauge is in the top part of the blue you have successfully charged your cars air conditioning unit.

STEP 4) Release the attachment from the tubing port and replace the dust cap back in it's proper place and you are done. The cars air should be cool and your compressor should cut off and on less often. If problems persist you should consult a mechanic or someone that has experience with air conditioning systems.

My air conditioner in my 2001 325ci does not blow air at all. What is the problem.


9 times out of the 10 it's the blower motor resistor in my experience. BMW uses an infinitely variable resistor that has a large heatsink attached to the back of it and they overheat.

We bought this van and it had been sitting for a year. everything checked out ok but the air conditioner will not put out cold air. does the van sitting that long affect the performance of the air...


The coolant used in ACs has very small molecules and no system remains tight enough to prevent loss. You probably only need to recharge it if it has not been opened. You can buy a kit with pressure gauge, coolant, connection hoses and instructions for <$25 US in auto parts stores. Make sure though that your system uses R134 coolant (especially if it is older) otherwise you may need a conversion kit to install first.

The air conditioner is spewing coolant out the nozzle that is used to put coolant into unit. Why? A tried putting coolant into the air conditioner and it isn't getting any cooler.


The a/c dont used coolant, the radiator does, check your radiator cap could be weak, the a/c system used freon, if not cool through vents on dash have your a/c recharge

Air conditioner works but no heat. Air blows cold air but no hot air.02 saturn slr


The inside heat is provided by a small radiator running engine coolant. If you don't have heat and you don't have scolding water pouring on your feet  then the coolant isn't running - most likely the valve controlling the flow is broken, replace it.It's easy to find, its located on one of the pipes leading from the engine and going inside the dash, with a control cable attached to it.

2001 chevrolet truck. the air conditioner works fine, but the heater blows cool air and does not get hoy.


Check the heater control valve. This valve opens to allow hot coolant into the heater core and closes to cut off the flow. It should be located on or near the firewall behind the engine. It should have coolant hoses attached to it. Look for an arm on the valve which should be attached to a cable coming from the heater controls inside. This arm should activate the opening and closing of the valve. Check to make sure it moves properly.
