The air going to your engine with a cold air intake system will bring the temperature down on your engine. This gives the car better mileage and performance. There could be many reasons why the system is not working properly. By following these steps, you can fix the system.
Step 1 - Take Precautions
Disconnect the vehicles battery before you try to do any repairs. This will eliminate getting shocked or causing any electrical components to short out. Always make sure your engine is cold and not hot. A hot engine can pose many dangers. It's best to let the car sit for at least an hour if you've been running the engine. If your system has a valid warranty, consider using this instead of trying to repair it. This will allow for an authorized mechanic to fix the vehicle at little or no cost to you.
Step 2 - Deal With a Short Ram
First thing you need to do is find out what kind of cold air intake you have in your vehicle. If it is a short ram then the system might not be getting enough air to cool the engine down because it is too close to the engine. There are two ways to fix this. One way is to install a heat shield. The other way is to replace the system you have installed with a new one with a longer ram.
Step 3 - Check for Holes
Check the holes on the cold air intake tube and make sure all of them are plugged. If there are any holes, you should plug them with grommets that came with the kit for your intake system. See if there are problems when you're idling. Listen for sounds of escaping air when your vehicle is idling with the hood open. If it does this can mean there is a vacuum leak in the cold air intake system.
Step 4 - Check for Blocks
Another reason might be something blocking the air in the intake tube. To check the tube you need to take out the system to get to the tube. The cold air intake system's tube has an air filter. Take off the air filter and check and make sure there are no cracks or tearing in it. If this is the case then you need to buy a new filter and replace the old air filter with the new one.
Step 5 - Check Water
One more reason for problems could be your air intake system or engine has been exposed to water. When the cold air filter is low to the ground, then water is a strong possibility. Buying an air bypass valve will help ensure that no water will enter your engine or the air filter. Contact a mechanic if you think water might be the issue.
Step 6 - Finish
Reconnect your battery to your vehicle. Crank the vehicle and check if the problem was corrected.
