2003 4.3's do not have an egr valve.
It is right beside the thermostat housing, and that is where the top radiator hose hooks to the engine.
Most major auto part stores will stock the standard EGR valve for a Vortec 4.3-liter engine. You may have to visit several to find one that has it.
10243880 if from 95-00 Vortec. Closest I could find.
you should be able to use the vortec rockers true rollers u should find on e bay for a resonal price
where do I find the egr valve on a 1999 Chevy Cavalier?
in what location can I find the pcv valve on my 2002 chevy tahoe
The EGR valve is located in the center of the intake, at the front of the engine, between the alternator and the A/C compressor. I've added a picture of the location to the links on the right. It is titled "Picture of EGR valve location, on 1996 - 2001 4.3L (262c.i.) Vortec V6 engines"
on automatic transmission
Owners manual, positive.
I am trying to find out if this is the correct t-case for my 98 jimmy 4l60e/4.7 vortec
if it's the 3100 V6, it is on the right side of the front valve cover
You may be able to find the diagram on the Chevy site. You can also find diagrams in the back of the Haynes Repair Manual.
