CHEVY EGR VALVE

2002 Chevrolet S-10

Engine Performance problem
2002 Chevy S-10 6 cyl Four Wheel Drive Automatic 75000 miles

I have to change my EGR valve on my 2002 S10 4x4 4.3L Vortec FI and I cannot locate the EGR Valve for the life of me. I found it on my other S10 that is 2 years younger but I can't find it on the 2002. Can you help at all?

Hello
Thanks for the donation

The 4.3L engine's EGR valve is located on the top, front of the engine. EGR valve is pictured below.. If you need replacement procedures just let me know..

Thats where the EGR valve is located on my 2000 S10 but on the 2002 there is no EGR off to the right of the coolant intake. Its almost like it has a different engine because I have searched up and down for it but I can't find it. And the one I have looks nothing like the one on my 2000.

You can give me your engine's ID code if you would like and I can look it up to see if it matches the 2002 S-10 4.3L engines. The 4.3L engine identification number is located on the left side rear of the engine block or on the right side rear and typically is a 9 digit number stamped or laser etched onto the engine. If it isn't there, it is probably not the original engine to begin with, but you can search for the ID code in another area so I can double check with the list of codes for the 4.3L engine..

A picture of what the 4.3L engine's EGR valve looks like is below..

I will do my best to find the Number but If I can't due to parts being in my way, can you use my VIN num. To check the codes you need to check?

Its stock and hasn't been worked on by anyone since I bought it new from the dealer.

Oh, well if you are the only owner then the engine is correct engine.

You must be overlooking EGR valve? Maybe there is another small component hiding the valve?

Is the engine code on showing that EGR is faulty?

My EGR valve that I bought looks like the one below.
My codes have not come up for it yet but after replacing the plugs, wires, cap, and coil I did research and found that the EGR can get stuck open and make the truck run like it has an oversized cam (which it does and gets about 10 MPG) so i just got the Valve and Gasket.

Sorry about that, the one I posted was just a basic egr valve shown. Your picture is the correct one for your vehicle.

Without being able to see your engine I really can't help you locate it if it isn't where it should be. Perhaps a call to your local Chevrolet dealer may be able to help as to where it will be if it isn't on the top front of the engine as it should be.

Or if you have a digital camera you can take a pic of where valve should be compared to the diagram and post it or email it to me?

I have a pic of the 2000 compared to the 2002:

2000 (missing EGR)

2002 (With EGR)

- Notice the EGR off the the right of the alternator (its kind of shiny in the 2002 pic but its not in the same spot on the 2000.

Yes, but I meant a pic of your actual engine so I can see what the area looks like where the EGR should be.

So your asking for a picture of the whole engine bay to try to see if you would know where the EGR valve is? (Correct?) Because the valve should be in the blank spot in the 2000 pic.
