If you are the owner of a 2002 Chevrolet Silverado, you may wonder where the EGR valve is located. In this post, we will show you where it is and provide some helpful tips on maintaining it.

Where is the EGR valve located on 2002 5.3 Chevy Silverado?

The EGR valve on a Chevrolet truck is located near the carburetor on the intake manifold. It’s in front of the oil filler tube on the passenger side of the engine. The EGR valve recycles exhaust gases from the engine’s exhaust system back into the combustion chamber.

What are the signs of a failing EGR valve?

If your EGR valve is failing, you may notice one or more of the following symptoms:

  • Your engine stalls or hesitates when idling
  • Your engine runs roughly
  • You experience decreased fuel economy
  • Your check engine light is on

If you notice any of these symptoms, it’s important to have your EGR valve checked as soon as possible. Ignoring the problem could lead to bigger issues down the road.

What happens if EGR valve is blocked?

The EGR valve is a mechanical component that regulates the amount of exhaust gas that goes into the cylinders. When it becomes blocked or fails, this allows too much exhaust gas to enter the cylinders, resulting in decreased engine performance such as a loss in power, acceleration, and even fuel efficiency.

Will a bad EGR valve throw a code?

A faulty valve is most likely to result in a misfire since it does not direct exhaust gases to one cylinder and this will produce an error code.
