I know our cars often have mixture problems between the trans and coolant fluids when the radiator fails. Has anyone here run a larger external trans cooler to prevent this from happening and for extra trans cooling? I've search but havnt seen much.

Here is the only aftermarket trans cooler install I could find: https://mbworld.org/forums/w211-amg/...r-upgrade.html

I have an 03 and I'm considering doing something similar. Judging by the size of the coolers on 04 and newer I think I would do something a bit smaller than this install. But it doesn't look to bad to do...

i am going to follow you on this one Bret. I think coolers runs about 40 bucks. Can you figure out what fitting we need.

Hey Shardul - My headers are first..lol! I have the ball flanges, o2 bungs and collectors...just waiting on the mandrel bends. This weekend I'm planning on dropping the exhaust and building the jig - but I'll look into the fitting while I'm under there and see what is needed.

were you able to salvage the flanges from the headers?

Oh yes - they will work perfect! Just need to hog them out to fit the 1.75" tubing. Ended up going with 1.75" to a 3" collector and I will run it right to the top of the cat...


" All the leg work has been done for you.
https://mbworld.org/forums/w211-a...r-upgrade.html " - Yes I posted that same link. I would just rather find an off the shelf fitting (MB-AN) vs. the weld-on.
