If you’re like most people, you probably don’t think about air leaks very often. But they’re a real problem – and one that can quickly lead to bigger problems. In this article, we’ll show you how to find air leaks in your car engine, and how to fix them.
What are the signs of an air leak in a car engine?
If you notice any of the following signs that your car engine may be leaking air, it is important to take action:
1. A strong gas smell coming from the car.
2. A loud popping noise when you start the car.
3. Car not starting well or having a difficult time getting going.

How to find and fix an air leak in a car engine
If you notice that your car is not running as smoothly as it used to, there’s a good chance that an air leak is to blame. Air leaks can cause your engine to overheat and eventually fail. Here are four ways to find and fix an air leak in a car engine:
1. Test for Air Leaks with a Scanner
If you don’t have the time or inclination to take your car into a mechanic, you can use a scanner to detect air leaks. First, identify the areas of your engine where air leaks are most likely to occur. This could be around the fan belt, radiator, or even the engine block itself. Next, use a scan tool to detect any leaks. If you find any, follow the instructions provided by the scanner manufacturer to fix them.
2. Check Your Engine Cooling System
If you see evidence of an air leak near the engine cooling system, it’s likely that water is seeping into the engine and causing it to overheat. To check for an air leak in your engine cooling system, first remove all of the coolant from the system and then use a pressure tester to measure how much pressure is required to pump water through the system
What to do if you find an air leak in a car engine
If you find an air leak in a car engine, the first thing you should do is stop the car and turn off the engine. If you can’t stop the car, turn on the hazard lights and pull over to the side of the road. If there’s an obstruction in the exhaust pipe, it will create a fire hazard if you drive away with the engine running. Once you’ve stopped the car, use a flashlight to look for air bubbles coming from the engine. If you see any air bubbles, use a screwdriver to carefully pry up on the edge of the plastic or metal cover that covers the air filter. Once you’ve opened up the cover, check to see if there’s an air leak. If there is, simply replace the filter and seal it back up with the cover.
