golffnutt Posted July 12, 2005 Share Posted July 12, 2005 My check engine light is on and the code reads it is a faulty EGR flow. I would like to remove the EGR valve and clean it and the passeage way out with carb cleaner before buying a new valve. Problem is it is screwed on from inside the valve and I see no way of how to unscrew it. Is there a special tool required? Can anyone please lend any advice on this? I would really appreciate the help very much. Thank you. Quote Link to comment Share on other sites More sharing options...
Toysrme Posted July 12, 2005 Share Posted July 12, 2005 What are you takling about? You simply unbolt the valve from the intake, and from the EGR pipe. Toyota Repair Manual My 3vz-fe EGR valve that I deleted for basic refferance. Quote Link to comment Share on other sites More sharing options...

I did indeed take the three bolts loose but I could not get the egr valve off the egr pipe in order to clean it good. How do I get the egr valve off the egr pipe? This is my problem. Thank you again for your help. Quote Link to comment Share on other sites More sharing options...
Toysrme Posted July 13, 2005 Share Posted July 13, 2005 It's been so long since I ditched it from my car I don't exactly remember. :( The EGR pipe is held into the rear exhaust manifold by a JIC compression fitting. That EGR pipe snakes up through a "block" that runs under the upper intake that is water cooled (most people thing the throttle body is cooled, actually it's not, the coolant flows through the EGR to cool it down, and exits the throttle body). The EGR "block" dumps the exhaust into the bottom of the intake manifold (in a seperate chamber) that routes it to the EGR valve, then the rest is obvious. Valve controls the flow and routes it back into the upper intake manifold. AFAIR there's nothing else to it. You take your bolts off, and pull the entire assembly off. It's a little exhaust gasket, I don't remember it being a silicon glue or anything (that would more than likely melt). The little actuators on top simply pul off.

I know I have to remove the egr valve from the egr pipe in order to clean the passage way and unstick the valve if that is the problem. I still have no clue on how to remove the valve from the pipe to check the valve, guess I will just have to pay someone an ungodly amount of money to do something that is probably ridiculously easy to do. Thanks again for trying to help. Quote Link to comment Share on other sites More sharing options...

saltyreefguy Posted November 11, 2006 Share Posted November 11, 2006 i took mines off it took a few extra minutes, cause the rest of the bolts are on the backside of the egr towards the firewall, i use a small cratsman ratchet with a small extension with the socket, and its got a metal gaskets for the 2 openings.
