Help needed- 14 G63 turbo coolant leak

Hi,

I found a puddle under my 2014 G 63 and opened the hood to investigate. It seemed like the leak was coming from one of the 2 lines going to the driver side turbo( I’m guessing it’s the return line.

Is this replacement something that can be undertaken in diy fashion at home ? Or should I take it to the dealer ( costs??)

I removed the fan and saw where the lines were, but it’s tight in here.

thought I would ask the forum on what other people had done. Thanks

Crack in the coolant line to driver turbo

Pretty sure this is a common issue that can be tackled at home. Join the Facebook g class groups, I’ve seen it discussed there.

The M157 engine in your G was widely used on “63” models across platforms and years.

This is not a G-specific issue.

I haven't done a DIY on this since my car was under warranty when these leaked. Looks like a total PIA but, from what I've read, it is a doable DIY.

ive searched it all, located the leak after taking the radiator fan out.

What I need help with, is how to unbolt these lines, and how to slip them out of the busy engine bay. I’ve searched the forums and googled it too.

just search g class group… there are only a couple active ones. G class owners USA maybe? I don’t recall the exact name but you’ll find it the way I did. Once in search or ask. There are a few techs and g gurus in there.

You remove it same way it removed on m278. It is tight space and lots of parts to remove. I suggest you take it to dealer.
