How does the a / C system cool the radiator?

This hot refrigerant is then cooled down by running it through the condenser. The condenser is cooled by ambient air in the front of your car just like the coolant in the radiator is cooled. On most cars the condenser is actually in front of the radiator and gets cooled first to make sure your A/C system gives you consistently cool air.

What to do if your air conditioner is blowing hot air?

If you discover this to be the reason why your car air conditioner is blowing hot air add Red Angel A/C Stop Leak to your vehicle’s air conditioning system to seal any leaks no matter how small they are before you recharge the system.

What happens to a car when the air conditioner is on?

A hot car is not only discomforting but also leads to serious damage to several other components. The symptoms of the car overheating due to the air conditioner involve the heating up of the engine, dashboard, and the seats a few minutes after turning on the AC.

Is the AC still warm after a recharge?

Recharged Car AC still warm Added Freon still not cold If your car’s AC isn’t blowing cold air it might be low on refrigerant. In most cases you can recharge car AC systems yourself with a can of refrigerant, a charging hose and gauge from any auto parts store.

Why does my car heat up when the AC is off?

When AC is off, the air hitting the rad is outside air temp, when the AC is on, the air hitting the rad has been warmed by the condenser and is now much hotter than the outside air. This is not usually a problem, if you have good air flow. Two things, the air flow may be blocked and/or the engine fan may not be turning.

Why is my AC not blowing cold air?

The chemical Freon or simply you can call it coolant is the reason why the AC cools hot air quickly. The chemical can run out if there is any leakage in the AC. Thus, AC would not work, as there is no Freon in the system.

What to do if your car is overheating when the AC is on?

Taking off the radiator cap can be very dangerous if the engine is overheated due to the AC. Park the car and put it into neutral. Revving the engine can help you to release some of this excess heat, but don’t do it too much in case there is some other damage to the engine.

What to do when your car AC blows warm at idle?

GM and others use either a three-relay set up to run the two fans at low speed for normal driving and high speed when the AC is on or the low speed can adequately cool the radiator. Other carmakers use a solid-state speed relay that varies the speed of the fans based on engine cooling and AC needs.

How often should I run the AC in my car?

We recommend running AC on full speed for 10-15 minutes every two to three weeks irrespective of the outside temperature. You could run it in the winter with the fan or air vent block, or maybe leave it on for some time before you lock the car and retire for the night.
