I have 2018 cascadia with 600k miles & my egr cooler is still completely dry and barely has any carbon build up in it. This truck definitely was idled a lot to have egr in such poor condition.

[@dell7054]

Same here have a 2018 with 490k. i dont idle period..

[@marcusford809]

mine didn’t go out until I got close to a million miles and I idle a lot

[@Steve.191]

Thank you 👍

[@EdwinMartinez-zt8sh]

Cay you show us how to remove the egr cooler

[@rafaelgallardo4380]

Yes it $2500 and is on a back order it will take 6 months for freightliner to send one

[@knightranger1783]

Thanks, where is your Shop ?

[@dell7054]

most of the time the truck has been IDLED alot and thats why u have these problems. I also have a 2018 cascadia with 490k and no issues.

[@jorgerodriguez6470]

[@rodrigocarrillo6479]

Bro tengo coolant en los protectotrs de calor q estan ahi abajo del egr de donde puede venir?

[@duleiraldaloi]

my EGR is bad too and i put 2 gallon od oil every 1000 miles is that pasble ?

[@rafaelgallardo4380]

Yo traigo un 2015 con casi 1000000 de millas I trae el original todavía le remplace los empaques pero le moví el egr actuarer I se descalibro I tuve que ir al dealer a que lo calibararan con la computadora

[@cascadia7244]

Is there suppose to be coolant in the egr or no? How else would you know that the egr cooler is bad if you are not losing coolant?

[@zburkst2928]

the coolant reservoir can start to turn black from exhaust gas
