EGR valve for '90

[AM Woody]

So I bought an EGR valve for my '90 GW, it was wrong. Brought the old one in, and the parts guy said "Chrysler." The first one was an AMC/GM type.

After digging through the books, they figured out the right one was listed for '91. But, they can't get it from any of the usual suppliers, only direct from Chrysler for $136.

Anyone found a source for these or a better price?

BTW, the number on it is 53006332

Thanks,
Andy

Check www.partsamerica.com (http://www.partsamerica.com) (this is the website for Advance Auto/Parts America/Checkers).They list an EGR valve for my '88(which should be the same as your '90)GP-Sorenson p#779-2321 $51.49.

I'll check it out. I sort of sounds like the part changed in '90, though, from AMC to Chrysler...

When I got the anti-knock kit from the Chysler dealer the EGR was a Rochestor (GM) unit. The kit was cheaper than the EGR valve alone.

Do you guys remember if your EGRs have a second vacuum hose fitting on the base?

This was the main difference between the one I bought and the one I have. Plus the diaphragm was WAY bigger on the new one. I would have had to have rerouted the PCV hose to use it...

Advance also carries it for 51 bones...

Mine is a single vacuum line connection.

I've ripped off all my emissions and capped most things off, except for the EGR, what does the EGR need to function properly?

I believe these are back pressure EGR valves. The original had the two hookups, one for straight vac and one connected to the EGR transducer which would allow the EGR to open when there was back pressure from the exhaust. The new ones have the back pressure valve built in, so you need to take the transducer out of the system.

Hmmmm. Interesting. Yes, it is a backpressure system with a transducer... I guess it would work the old-fashioned way...
