Why My Car Blowing Hot Air

A car is a major investment, and as such it’s important to take good care of it. One common problem that can occur with a car’s air conditioning system is blowing hot air. In this article, we’ll explore the causes and solutions to this issue, and help you keep your car cool and comfortable during summertime.

Causes of Car Blowing Hot Air

If your car is blowing hot air, there are a few things you can do to try and fix the problem. The most common cause of a car blowing hot air is a faulty thermostat. If the thermostat is not functioning correctly, it will not be able to control the temperature in the car, which will cause it to heat up and blow hot air. Other reasons for a car blowing hot air include a bad air conditioning unit or a loose or broken fan belt. In most cases, however, resolving the issue will require a repairman. If you are unsure whether your car needs a repair or not, contact a mechanic for help.

Fixing Blown Head Gaskets

If your car is blowing hot air, there’s a good chance your head gasket is gone. Head gaskets are one of the most common and costly engine problems, and you can fix them yourself for cheap. Here’s how:

1. Remove the intake manifold cover. On most cars, this is simply a few screws that hold it in place. Once it’s removed, you’ll see two manifolds side by side. The one on the left is the intake manifold, and the one on the right is the exhaust manifold.

2. Check for signs of leaks. If your car is blowing hot air, there’s a good chance there’s a leak somewhere in between these two manifolds. If you find evidence of a leak, start by replacing the gasket between the manifolds (usually just a few dollars from your local parts store). If that doesn’t solve the problem, then you may need to replace both manifolds.

3. Reassemble everything correctly and test the car for leaks. Be sure to replace any gaskets that need to be replaced as you go! Once everything is reassembled correctly and tested, you’re ready to go back

Replacing the Air Conditioning Unit

If your car is blowing hot air, it might be time to replace the air conditioning unit. A blown air conditioning unit can cause a number of problems, including reduced visibility and discomfort, and may even result in a car fire. Here are some reasons why your air conditioning unit may be blowing hot air:

-A blocked or clogged filter: If the filter is blocked or clogged, the airflow over the compressor will be significantly reduced, resulting in overheating and a likelihood of a blown AC unit. In order to check for a blockage, remove the front fascia panel and look for debris or dust on the fan blades or inside the air conditioner ducts. If you see an obstruction, clean it off with a vacuum cleaner.

-A worn out compressor: Over time, the compressor can wear out, causing it to overheat and potentially blow hot air. To check if your compressor is worn out, turn off the car and remove the front fascia panel. Look for cracks in the casing or dents in the fan blades. If you find any damage, have your AC replaced before it blows up!

-A dirty evaporator coil: The evaporator coil uses Freon to
