Voyager 2.5 CRD 2003 - EGR valve cleaning
 

Hi All
I am thinking of cleaning the egr valve on my wife's voyager over Christmas (already planning what to do with this time off). She does a lot of around town driving,so I guess it may need doing.
Could somebody tell me where I would find it,if it is easily accessible and if anybody has a picture,that would be a big help?
Many thanks

Merry Christmas
John

EGR Clean
 

Hi John,
Not got answer here for you but quite interested in your thread as a bunged up EGR valve can cause problems and possible shutdowns when you don't want it. May do mine SAP if I find where it is as I'm not complacent with these engines.
I got a Chrysler Service Manual disc off E-Bay that was cheep and it even gives all the fault codes. Using it for suspension work just now.

Haven't done it myself, but here's the details

EGR Clean....
 

Hi Richard,
First class reply....

Goggs...

Thank you very much for the response
I am going to have a crack at it tomorrow
Thanks and Happy New Year
John

Hmmm: That all seems very different from my 2007 2.8CRD. If you do not have a problem I would simply use a tin of Wynns Diesel EGR3 cleaner - you spray it into the air inlet after the air mass sensor with the engine running...

can you blank of a e g are valve on a 52 plate voyages 2.5td and will have any engine light probe many thanks glen

you will probably get the MIL lit, but try it, see and report back to us.

In my opinion blocking the EGR does no harm to the engine, other than confuse the ECU slightly.
Rather than blocking you are better off having the EGR remapped in the ECU so that it is never open and the rest of the airflow maps modified to account for the reduction in air flow. However this will cost a lot more than fashioning a blanking plate out of biscuit tin lid

EGR Clean out.
 

Hi, would be interested to know how JohnDavis got on, as its like the Thermostat renewal, its said to be a two and half hour job as you have to remove wiper motor and tray...
Was going to renew my Thermostat and got one from my Motorfactors. Yes First Line parts company has this engine using a normal thermostat under number 174.80. Showed him picture of right Chrysler unit and after checking out picture comparison he said it was made in Russia. Latvia to us, as we have been told on here.

had to have the egr deleted from the ecu cost £150 all done no more big clouds of black smoke now just have to replace glow plugs or relay engine code time ?

Bought EGR cleaner but i cant locate the egr and air mass sensor :(

The mass airflow sensor is connected by a short rubber coupling to the air filter box.

In my opinion, the down side of these EGR cleaners is that any junk dislodged ends up in the engine. I'd much rather dismantle and use a blowtorch on the manifolds and a wire brush on the valve.

I agree with you tfb. When installing my EGR, the EGR out pipe was 40% blocked at the bend. Only one way to clean this ...!

Hi, reading about EGR cleaning out through the threads. Is there any new joins whether metal or material required for sealing.

just use old seals --- they should be ok + appropriate silicon gasket sealant. on the egr valve i received the, the two holes for connecting the out pipe were not threaded like in the old egr valve, so i had to improvise and use a couple of bolts and nuts. it's a tight fitting so suggest you connect the valve to the outgoing pipe BEFORE installing in engine compartment and attaching to exhaust manifold.

Would not just removing the Vacuum pipe that activates the EGR and sealing it stop it from working?

See Youtube for vid of isolating EGR this way. One of the top whacks on here did this quite recently. Only thing about isolating it this way, is if it is partially blocked and jammed slightly open there will be no difference to your diagnosis. So only answer is to clean it out and check operation.

Where exactly are the glow plugs, can someone be kind enough to mark them on my engine please

location of glow plugs
 

1st from left is behind the alternator
2nd from left behind the power steering fluid bottle
3rd behind the exhaust intake just left of oil dipstick
4th behind and below the egr vacuum controller (that hing just to the right of the dipstick)

All are easy to access... just need to remove bits out of the way.

Just posted elsewhere I have stopped my EGR Valve working quite simply, cut the vac pipe from the servo, cut a piece of spill pipe or similar about 2 inches will do, push a ball bearing or similar half way up pipe rejoin cut vac pipe with spill pipe, the bearing stops the vac before it gets to the actuation valve on the front of the engine and to the casual eye nowt has been fiddled with, I have noticed a more flexible engine with a lot more get up and go, time will tell

AS said this will ot work if EGR Valve is partually stuck open.

One noticeable point, as the EGR water cooler no longer has hot exhaust running through it the engine runs cooler.

Other makes of car have code relating to rich trim coming up after isolating EGR valve. I can see the reason as engine now has more oxygen going through it and more charge air is being asked for.

I will keep an eye on Consumption and report back, so far I have covered about 700 miles and all seems ok with fuel lasting longer, and the engine getting stronger, but I didn't take proper fuel readings, so will do a better calculation on next fill to fill

Yes report back any results John.
