How to Fix an EGR Valve on a 2003 Chevy Tracker
- 1). Locate the EGR valve. It's between your firewall and engine block. The EGR looks like a thin, grooved metallic disc.
- 2). Remove the rubber vacuum hose attached to the top of the EGR valve. It will pull free with a small amount of force.
- 3). Attach the manual vacuum pump to the top of the EGR valve. The manual vacuum pump can rest on your engine and will test the pressure of your EGR valve.
- 4). Start your Chevy Tracker. Return to the manual vacuum pump and use the tool to apply suction force in the EGR valve. Your Tracker will idle correctly. However, a steady idle of your engine with the manual vacuum pump attached confirms your EGR valve needs to be replaced.
- 5). Turn off your vehicle. Let your Tracker sit for five minutes before removing the manual vacuum pump.
- 6). Remove the bolt attaching your EGR valve to your Tracker with your metric ratchet set. The first crank of the ratchet will be the most difficult. Apply as much force on the handle as needed until the bolt initially spins free.
- 7). Detach the rubber vacuum hose attached to the bottom of your EGR valve. You'll need to give the hose a few good tugs with your hands until it slides free.
- 8). Attach the bottom rubber vacuum hose to your replacement EGR valve. Securely push the hose connecting to the EGR valve's bottom port as far as it will allow.
- 9). Bolt the replacement EGR valve on your Chevy Tracker with the original bolt. Use your metric ratchet set and securely fasten the bolt until the ratchet will not allow further tension.
Attach the top vacuum hose to your EGR valve. The hose will slide on the top vacuum port, similar to the defective EGR valve. Securely fasten the vacuum hose.
