Title: 1993 EV - where is the EGR valve?
Post by: duckdive on August 04, 2016, 09:39:19 pm

Can somebody help me out and tell me (photo or diagram or describe) where the EGR valve is?
I want to clean it out cause I didn't pass smog on a 15mph NO (in California). It is a high mileage EV so I want to take a look at the EGR valve anyway.

I swear I cannot find it... online or in the EV.

There won't be an EGR on a 93 EV with an AAF engine.  If you've got an ACU engine on the other hand, you should see a small pipe coming off the exhaust that feeds an EGR device.

Yes, I've seen that diagram.  I looked all around the coolant reservoir & distributor & other areas.  Not sure.

But, silly question... how can I find out my engine type?

The engine number ("3 engine identification letters" and maximum "6-digit serial number") is located behind the cylinder head cover on the cylinder block.

There is also a sticker attached to the cylinder head cover with "engine identification letter" and "serial number."

The engine identification letter is also located on the vehicle data plate.
