A 3-Step Guide to Installing Your Air Inject Check ValveAn air inject check valve is a component of a car's air injection system that takes part in letting fluid pass through the valves for a more efficient combustion in the engine. But despite the fact that the check valve is part of a whole assembly, it does not necessarily mean that it will not get damaged as a single component. There are instances when the air injection check valve becomes defective because of constant wear and tear. Some of the most common problems faced by a check valve are corrosion and overexposure to high temperature. And since most check valves work automatically, there is no way for people to address it but through replacement.

Needed tools and materials:
Preparing the vehicle
Park the vehicle at a spacious area where you can work comfortably. If in case you are replacing an old check valve, make sure that the car temperature has been cooled down before you start the process. The air injection valve is often exposed to extreme heat, and it could be harmful to begin right away when you have just turned off the engine.
Locating the check valve
Find the check valve on your car. Since it is part of the air injection system, you may find the check valve on the area where the catalytic converter is also placed. The component is quite small, which means that you would have to look through the system carefully, especially if you are doing this the first time.
Installing the check valve
Install the air injection check valve using one of the wrenches that you have. Simply twist the wrenches repeatedly until the valve tightens. See to it that the part is installed properly so it won't be easily removed, especially while the car is moving.
Checking the working condition
Check whether the newly installed valves are working properly. If there seems to be a problem with the part, try to take it out again and repeat the installation problem. If nothing improves, have the vehicle checked by experts in case there are other damages.
Tips and warnings
- Using hand gloves is also an option if you don't want to risk getting hurt while installing the check valve. But if you are more comfortable working with your bare hands, there is also no problem with that.
