Due to the very large number of people coming to all23bunnies looking to replace an EGR Valve, I have decided to write an actual How To Replace and EGR Valve instead of a How to Watch Someone replace and EGR Valve.

See info below:
How to replace an EGR Valve:
First of all, if you really want to replace the EGR valve-take it to a shop. In both the Ford Escort and the Toyota Camry the bolt that holds the EGR Valve to the exhaust pipe is difficult to reach. But you can try and you might succeed with the right tools. If you are working on a big GMC truck, you are set those are easy as pie to replace.

You need:
A socket set
A small drill bit or wood screw
A small handled, wide mouthed wrench
A phillip’s head screwdriver
A can of carborator cleaner

The step-by-step:
Disconnect the negative terminal of the car battery.

Remove the air supply hose, ( or whatever the thing is that comes off of the air filter) undo any electrical connections that might get in your way around the EGR Valve.

Disconnect the vacuum hoses from the EGR valve. Be very aware of which hose goes to which port. You may even want to mark them.

Remove the mounting bolts that hold the EGR Valve to the engine. These bolts face the windshield and require a socket wrench (a half-inch socket should do, try a ¼ inch).

You need to unbolt the EGR valve from the EGR Tube. Treat the bolt with liquid wrench first. I don’t care how strong you are, if you’ve Googled How to Replace an EGR Valve and found this site, you need Liquid Wrench. Grab a wide mouthed wrench with a short handle. There is a super handy wrench with a handle that sticks up perpendicular to the wrench head. Try one of those.

If there are holes in the EGR valve, replace it, if not, clean the puppy. It just isn’t worth the freakn’ work to take the EGR valve off to replace it if you don’t have to.

Use half a can of carborrator cleaner to spray into the valve. Let it sit for a while. Use a small drill bit or long wood screw to scrape out the build up in the valve.

The other day, after procrastinating for four straight days, I finally went down to the neighbor’s house below Chad and Leilani’s to ask if I might use their driveway to replace the EGR Valve in Bubbles.

Yesterday, late in the afternoon, I made up my mind to replace the thing. Here is what I learned:

Materials needed:
manual
wrenches
socket set
work gloves
down coat
brown suede high heels
One Chad
Two neighbors (male)

The step-by-step
Place tools near hood
Do as manual says and jack car up off ground
Open hood
Unfasten the negative connection of car battery
Look at EGR Valve, follow EGR Valve tube to where it attaches to exhaust-manifold-area-thing
Realize the manual is dead wrong
Lower car

To remove EGR Valve one must:
Unfasten mounting bolts on EGR Valve
Loosen Large Bolt that fastens EGR Valve to EGR Tube

To loosen Large Bolt that fastens EGR Valve to EGR Tube one must:
Detach EGR Tube from Exhaust manifold area thing

To Detach EGR Tube from Exhaust manifold area thing one must:
Detach Mounting Bracket of EGR Tube

Attempt to place rather large wrench into several small spaces
Re-attempt
Watch as six sided bolts become rounder, softer bolts
When trying to loosen a bolt that is too tight, locate a pipe to slide over wrench handle- it will provide more leverage
Attempt to loosen each bolt several times
Avoid hitting yourself in the head with the pipe
(or don't avoid hitting yourself in the head with the pipe)
Curse

Stand and look at car
Males, when they detect a woman in high heels holding a wrench over a vehicle’s engine will accumulate

At this time, it is a good idea to do one of two things:
Snarl
or
Step away and regale males with anecdotes and summarize Woman in the Dunes

Note:
If you give a man a wrench, you will never get it back
It doesn’t matter if you know what you are doing, it matters as who has the wrench

Conclusion:
If you ask for help, be prepared to let go of the project. Thank everyone involved. Order a large thank you pizza and not a medium one.
