The EGR valve is located on the drivers side of the engine beneath the VORTEC air intake on the 4.3L V6 engine. You will notice that it comes directly from the exhaust manifold and feeds back into the cylinder. If the part is bad the rubber elbow which connects the EGR back to the engine will likely burn in half until the part is fixed. Youll hear a loud popping sound coming from youe engine if this is the case.
There is no EGR valve on the 2002 4.3L (code W)
2003 4.3's do not have an egr valve.
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
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.
The 1997 S10 Blazer has an egr (Exhaust Gas Reclaimer) valve. It also does not have a point distributor, it is electronic.
Is it possible to just eliminate the egr in my '87 Chevy S10 2.5 liter pickup? I find on cold days it runs very well but after it is warm it bucks and surges. Eliminating the EGR valve is a crime, punishable by a $10,000 fine. You need to have your EGR valve, Computer, and/or engine checked and repaired.
The Exhaust Gas Recirculation Valve on a 1989 S10 is located in the valve cover. It is toward the front of the motor.
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.
A faulty EGR valve can cause a 98 Chevy to fail a smog test. The oxygen sensors should also be tested as they can also cause a 98 Chevy to fail a smog test.
What engine???
there is no such thing as an egr position sensor
