2008 mbe4000 erg cooler replacement

I've had my 2008 sterling with a MBE400 13 speed 3.90 gears. Has Anybody have problems with egr coolers. I have replaced 4 now and I just
had that one go within just under 6 months. Has anyone else had this problem or is it just me!!!!!!!!
Detroit wants nothing to do with me saying they don't have this problem anywhere else. Is it my luck or are they just not admitting a problem.

By the way I only have just under 800k. Just throwing it out there

THANKS

 

This Post definitely belongs in the Garage forum. Lets see if we can get it moved for you by a Mod. Good Luck !

 

I went through.....ONE on my 2006, in 884k miles.
So it is indeed not a common problem. I think I have a spare one, from a motor I tore apart, at home.
What is it doing exactly? Leaking into the intake?
I blocked mine off, at both ends, so if it leaked, it couldn't enter the motor.

have serviced a fleet (15) for 6 years.have had 1 leak 2 years ago.replaced.no further problems.

 

Thanks To All For Your Thoughts And Input. There Is A Shop that wiill reprogram my ECM so that it over rides the DPF symtem,But I have to replace the Cooler First. I am a little reluctant To, but I Know of People Who Have And It Works Great.

GOT TO GIVE THIS SOME MAJOR THOUGHT

 

My 2006 was blocked off for too many years to count, worked great.
See if they are the same, if so, how about $50 plus shipping for the cooler from my old motor?

One possibility with repeat failures of EGR coolers is improper installation. If it is installed slightly misaligned, once all the connections are bolted in place the cooler body will be stressed and prone to cracking. Over torquing fasteners is an easy way to over stress them as well.

 

is it possible to do it when its time to replace, or should i start doing it like u now straight ahead

 

The Mechanic that is installing does this on a regular basis. I don't think thats my problem

 

His way of installing the cooler may be why he is doing them on a regular basis.
