Forrest Gump 9 Posted December 13, 2018 Report Share Posted December 13, 2018 Hello all I need a 6” pipe with a groove for O-ring and a bracket made. In their infinite wisdom MB is using biodegradable parts in their vehicles. One of the parts is a little block that attached to the engine block so coolant can flow thru to the heater core. When the part fail, all of the coolant will be loss almost instantaneously. And this all can be fixed with a simple metal pipe with a bracket to bolt to the block.

Forrest Gump 9 Posted December 13, 2018 Author Report Share Posted December 13, 2018 I read it as a 6" diameter pipe lol. I get it now. My bad, 6” long. May be 3/4” diameter Quote Link to comment Share on other sites More sharing options...
Forrest Gump 9 Posted December 13, 2018 Author Report Share Posted December 13, 2018 Found a place at the corner of Bethel and Kenny. We’ll see how my contraption work. When this MFer fails, you’ll need to removed the intake manifold to get to it. And in order to removed the intake manifold you’ll have to remove the direct injection fuel lines and the intercooler charged pipes (which I still have nightmares about). Hopefully this part will work out because I don’t ever want to replace it again. Quote Link to comment Share on other sites More sharing options...

10phone2 Posted December 14, 2018 Report Share Posted December 14, 2018 a co-worker has a friend that owns a machine shop that does one off aviation machining over by rickenbacker (sp). I can ask them what the shops name is if you want. Quote Link to comment Share on other sites More sharing options...
cdk 4219 Posted December 14, 2018 Report Share Posted December 14, 2018 Another quality Mercedes plastic part. Quote Link to comment Share on other sites More sharing options...
Forrest Gump 9 Posted December 15, 2018 Author Report Share Posted December 15, 2018 Another quality Mercedes plastic part. Yeah, you’ll love this. This is the 6th fitting that’s gone bad on the 2012 model year. The other five fittings were minors leak that will not cause engine damage. The reason I want to get this “permanent fix” is my wife GL550 also utilizing the same engine and it’ll be next in line to get all of these fitting replace.

Otis Nice Posted December 15, 2018 Report Share Posted December 15, 2018 Another quality Mercedes plastic part. I have owned 2 VW's. Both had water pumps with plastic impellers. Both split in half. VAGlol. Quote Link to comment Share on other sites More sharing options...
cdk 4219 Posted December 17, 2018 Report Share Posted December 17, 2018 I should have said all German cars, plastic is definitely not their strong point. Quote Link to comment Share on other sites More sharing options...

cdk 4219 Posted December 17, 2018 Report Share Posted December 17, 2018 Well looks like I will look for a 2016 CTS-V instead of an E63 or amg gts if this is the issue. Those plastic pipes with the extended life coolant isn’t a good design for any longevity. That coolant is like acid to any of those plastic parts or adhesive.

99StockGT Posted December 17, 2018 Report Share Posted December 17, 2018 There are a long long list of reasons I hate modern MB parts designers. Crap materials, overcomplicated designs, blind bolt holes with various depths of the SAME FUCKING BOLT... *shivers* Quote Link to comment Share on other sites More sharing options...
cdk 4219 Posted December 17, 2018 Report Share Posted December 17, 2018 Yea, I keep thinking the newer ones may be more reliable, nope. Quote Link to comment Share on other sites More sharing options...

The newer MB with the turbos that sit in the V are even worse. People are reporting the biodegradable fittings are failing at 50k miles.
