Cold Start Valves

Like most of the valves in your car's engine, your engine is not only improved by the function of the cold start valve but can also experience serious damage if something goes wrong. The cold start valve's primary purpose is to substantially shorten the time it takes for your car's engine to start, especially when it's cold. Starting your car up after a cold winter night can be hard even with this unique valve, but would be virtually impossible to do with out it. I think it goes without saying that you need your cold start valve to be working, and we haven't even gotten into the dangers of a damaged valve. If you are noticing strange sounds coming from your transmission or your car slowly starting, it's probably time for you to replace your cold start valve, but a little time to understand it before you start working with it.
How it Works
When your car engine is starting, it requires a richer fuel and air mixture than when its already running, especially when the engine is cold. When you go to turn your ignition, pressurized fuel passes into this device and is mixed with the air that is pumping through the valve. It limits the amount of air mixed into the fuel however, effectively enriching the fuel and air mixture and helping the engine to start faster. It has three wires, an electrical line (this tells the valve how much air to mix with the fuel, depending on the temp of the car), a fuel line (this pumps fuel into the valve) and an air line (this pumps in the air). Within this small device, fuel is converted into a mixture capable of starting your car but as with most things (especially cars it seems), this valve will eventually stop working properly.
What Can Go Wrong
To be honest, a lot can go wrong with your cold start valve because it experiences high levels of air pressure on such a regular basis. The main problems people experience related to their cold start valve is that their engine wont start, they notice a leak from the valve, or it gets clogged. These problems often occur either because of too many starts in a short period of time or no starts over a longer period. Although inconvenient, if you don't have a leak in your valve, you and your car aren't in immediate danger. If you do though, fuel is leaking into your engine: this is an incredibly serious fire hazard. To prevent this from happening, check your valve regularly for damage and pay attention to the sound of your transmission when you turn the car on. If you notice a change it might be time to replace your cold start valve.
Replacement Tips
* When you buy your next valve, find one that comes with a set of directions. Replacing this valve can be a tricky process.
* The most difficult part of the replacement process is often unscrewing the valve from it's place. The screws holding this device in place are often very soft, so be careful not to bend them with a clumsy screwdriver.
* Check to see if your car brand makes cold start brands specifically for your car before you buy a more generic valve.
* If you decide to get a more generic valve, make sure it is compatible with your car.
