Facts about the Vacuum Pump Check Valve

You need it, for example, for your vehicle to brake properly. It's found in most cars out there as well as trucks, vans, and SUVs. Even motorcycles make use of these valves.

At any rate, you've probably come across this guide because your mechanic told you that your vacuum pump check valve is busted and you're looking to find an online solution to your expensive problem to alleviate your expenses. Keep on reading to find out more about this car part.

Repair and Replacement Tips

  • When to Replace: Your vacuum check valve may need to get replaced if your brakes don't work anymore or if they're not as responsive. Checking if it's the valve that requires replacement can be tricky since there are other car parts that can cause your car to stall or become less responsive than usual. Wear-and-tear of the valve can help facilitate brake failure. Have your mechanic check to see if a broken valve is what's causing you break distress.
  • Finding a Replacement Valve: Refer to your mechanic on which replacement valve you should get. Compatibility is important. You should also check if it's made of anodized aluminum or some other material. The valve is typically found at the end of the hose in order to supply vacuum flow to your intake manifold. You should also get a valve with less than 1"Hg low cracking pressures while also offering high flow capacity when push comes to shove.
  • Learn the Different Check Valve Types: Don't buy cheap parts to save money since you'll end up sacrificing your own safety and check valve performance in order to maximize your investment. Instead, go for affordable quality or cost-effectiveness. You have the option to get spring-loaded check valves for high-pressure systems with high-cracking pressures at the cost of restricted airflow. Meanwhile, low-cracking and high-flow types are also available and are usually included in most middle-class-budget vehicles.
  • OE-Standard Is the Way to Go: OEM or Original Equipment Manufacturer parts are great if you can afford them or if they can be provided to you for free because your car is still under warranty. Otherwise, most motorists look for cheaper universal-fit valves that are compatible with multiple vehicles. Your mechanic, gearhead friends, or motorist neighbors should have an aftermarket recommendation handy to give to you. Or you can check online for more details.
