Depends on how mechanical you are. You will have to get at it, unbolt it, clean the gasket surfaces, install new gasket and bolt the thing in. Bust the head off a bolt, and you are in deep poop unless you are good at extractions. Look at a parts store website to see what it looks like, then find it on your engine. If getting to it is fairly straighforward, go for it, on the other hand if you have to pull a bunch of other stuff off just to get started leave it to a pro.

I have a 2002 Saturn ls1. I put a code reader on it and I need to remove and clean egr valve. How is this done


locate your EGR valve. Saturn EGR valves are usually located near the intake manifold and throttle body. carefully remove vacuum hoses from the valve. then unbolt it. Remove the EGR valve and discard the old gasket. the valve has 3 bolts on it, 2 in front and one in the backside. if you can not let it soak for a few hours, then clean with shop towels and cotton swabs to remove built up carbon deposits. replace EGR valve with a new gasket. Good-day!

My egr valve keeps cracking


What you should know is the EGR valve is an Extended Warranty part under Federal Pollution guidelines. While the mileage and age of your vehicle may have exceeded the Warranty period of the original Factory part, there are some guarantees on the replacement part depending on the brand.

That said, it is The EGR that is the victim rather than the cause of your problem. Overheating of the EGR is the likely cause of the cracking. The EGR is not apparently opening fully or at all.

This is a problem. Because the onboard computer should be monitoring the various switches that control the opening and closing of the EGR valve.

I would suggest having the passages to the EGR valve cleaned. Have the Vacuum lines to the EGR valve checked for routing between switches. Incorrect routing of the Vacuum lines can also cause poor acceleration.

Smoking, EGR valve failure, etc can be a clogged Exhaust system too!

Before buying another EGR see if you are eligible for a free replacement.

Have a compression test done to verify engine health and replace the sparkplugs at that time.

Please comment on my info.

Hi. I understand I need to replace my EGR valve on a Pontiac Montana, 2000. (3.4 L) Any tips or guides on just how one gets to this valve? (behind air intake assembly)


it looks much harder then it is, the best thing for you to do is buy the new EGR valve so you have a reference to look at. then remove the air intake hose and top of air cleaner box, then look at were the throttle and cruse cables attach's to the throttle body you will need to remove the steel bracket that holds the cables to the throttle body then remove the two bolts that hold EGR valve and the plug in on the top and replace the valve, take your time and don't panic at is basic auto shop 101. Just think if you can get it done your self ( and you can ) think of all the money you will save............HAVE FUN

How do i replace the egr valve sensor


The Vehicle would only stop, if the EGR stuck open,momentary at low speed,and dumped too much exhaust into the intake. The entire EGR Valve ,if bad, needs to be changed. The sensor is part of it. Have her find a good shop or a friend do it at home. Pretty easy.

Check for

vacuum leaks on intake manifold,

the air tube between the air filter.

intake manifold vacuum hose.

===
clean throttle plate with Berryman carburator cleaner

SEE sample picture HERE
===

Also remove carbon built up behind the EGR valve and the EGR passage tube.

===

Vacuum leak WILL offset the intended 14.7 to 1 air fuel ratio.

More un-metered air (leaks) will lean out the fuel mixture.

Use small amount of Berryman carb clearer at potential air leak area will help you identify trouble spot.

At idle,just spray and listen for the RPM surge.

The in-rush of carb clearer will increase the RPM on the motor.

Record the problem spot(s) and address it later.

===

EGR carbon built up require 2+ hours to clean from start to finish.

You will need a new EGR base gasket before your start.

Locate and remove the EGR valve after the vehicle is cool down.

Carefully record the connector and vacuum line (for older vehicle) location by drawing an easily to follow diagram.

Remove the EGR valve.

Inspect the location of the carbon built-up inside the valve and the EGR passage tube.

SOAK these areas with WD-40 spary.

You will need a small screwdriver,cloth hanger and lot of newspaper and time to get this cleaning done right.

RE-SOAK the carbon and let it sit for over-night will also help.

One the last round,pass a shop vacuum of the EGR valve and the passage pipe.

Install the new EGR gasket and connectors.

Allow the vehicle to warm up outdoor to burn up any remaining WD-40.


Take it for a test drive.

Go to www.hmaservice.com and register( Vehicle by VIN). Afterward, you have access to shop manuals, service bulletins, wiring diagrams, etc. about your vehicle.
NOTE:.. EGR RESTRICTION POSSIBLE between exhaust manifold and EGR valve... check it out before replacing valve.... replacing the valve may not be the solution... having it properly diagnosed is!

I don't think that's the EGR valve that the shop is talking about for that kind of dollar figure. More likely the injectors or injector pump....accordianman
