I want to clean my EGR valve on my 94 Z28 BUT I DONT KNOW WHERE IT IS COULD SOMEBODY HELP PLEASE

 

bolted on the back of the intake. It's not very hard to get to. Just lay down on the nose and engine and reach for the back. It's more to the left side of the engine. (On the right side if your laying down on the motor.)

 

use carb cleaner to clean it. It is held with two screws....easy removal.

 

how do i remove the egr valve

 

Just reach back there with an end wrench and take it off? whats the problem? i believe its like a 13mm but its been a long time.

 

2 bolts actually, but close enough.

A question for you... what are you trying to do? Remove the valve and clean or replace it? Remove the complete EGR system?

 

I see you already have a thread started on this problem, only an hour of so ago.

Helpful Hint 101: Do NOT start a new thread that is basically a continuation of a previous thread. It means people have to start all over to understand your question and provide the right answers. In effect, you waste people's time, because they don't know about the other thread, and are asking or answering a question that is a duplicate.

I will "merge" the two threads.

 

i think their 10mm

The hold down nuts are 1/2" wrench size. They are not metric.

 

So a 13mm fits. I just figured it was metric and got a 13 to fit. I guess i'm glad they weren't seized or i would of rounded them off.
