The Exhaust Gas Recirculation Valve on a 1989 S10 is located in the valve cover. It is toward the front of the motor.
The EGR valve is directly under the hood on the 89 Cavalier.
If you want to locate a new egr valve, check with your local auto parts store. If you want to know where the egr valve is located on your vehicle, post the year and engine size of your S10.
There is no EGR valve on the 2002 4.3L (code W)
2003 4.3's do not have an egr valve.
It depends if it is a 4.3 or the 2.2 engine but, in general the EGR valve is located on the intake manifold.
What engine???
The 1989 Honda Civic is not equipped with an EGR valve.
The round black object sitting bolted to the back of the throttle body. Entwined in the fuel lines; difficult to remove. If all else fails follow your tiny vacuum hose from the vrv valve.
The egr valve on the 351 engine is located on the left side of the throttle body on the top of the engine.
The EGR valve for that 01 S10 2.2 L engine would be found on the top rear of the engine.
Check your EGR valve Check EGR valve
The EGR (Exhaust Gas Recirculation) valve opens when vacuum is applied. The EGR vacuum solenoid opens and closes the vacuum supply to the EGR valve when it is commanded to do so by the ECM (Engine Control Module).
