Haha We got burned on that so many times we made a bung and pressure test every time we replace these gaskets Before its totally assembled! Not worth getting it all assembled to find you got a leak 1/2 hour before quitting time! Note! Most EGR coolers can Now be removed with out removing turbo ect. You can saw off 2-3 hours of work by jacking the front of the engine and moving the shock bracket out of the way! (MOST Models!)

(Don't tell the warranty dept) I tried that on a rusty Volvo the other night . I could not get it to clear. Had to pull the turbo and of course both bolts in the turbo broke off. Spent the rest of the night drilling and tapping the holes. At my old work I built a jig to bolt the turbo to so it would fit it in the drill press to drill out broken bolts, it was handy. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/70593-if-you-had-the-opportunity-to-redesign-the-mack-chassis-and-the-mp-engines-what-would-you-change/page/4/#findComment-513659 Share on other sites More sharing options...

Oxy you simply find a pipe that fits the outlet hose of the egr cooler make a cap with a regulated shop air connection 40 psi ! you can also use this to test for egr to coolant leaks!

Pro you need to stop working on them Volvo engines they are Evil! No doubt Pro has the best job security out there. Volvo wants to make sure plenty of mechanics and parts guys are employed worldwide. I think that’s their end goal…They come to the engineers and ask them to make the next version shittier than the last and to create new parts that fail for the ones that are currently working.

Onyx610 Posted October 27, 2022 Share Posted October 27, 2022 Honestly that’s all I can think of for that. You guys would have a better idea as I’m not super familiar with them. Also that problem was hit or miss and I think Bosch made that pump?

Joey Mack Posted October 28, 2022 Share Posted October 28, 2022 they solved it with a hex headed spindle and the same fancy plastic gear...
