Thanks rockinwagin.....I wasn't sure if some extra-ordinary stubby wrenches or crow foor wrenches would be needed. I'm doing the shocks and mounts at the same time so I've got that going for me at least....
Regards,

I welded up a wrench to make the job easier...it's like a flare wrench but with 12 points and reinforced. I've never seen one like it for sale. Now the bad news... I would be very reluctant to loan/send through the mail or rent this tool to anyone I don't know. Sorry.

Get a can of PB blast.....soak it for a week....adn buy a set of metric flare wrenchs at home depot, sears or Lowes......they come in handy on tight nuts and bolts.

Brad , How about a picture ? Wrench placed on a quadrille lined paper for picture would be even better...

The big nut on the cooler lines is a 27mm. But since 1-1/16"=26.9875mm, the SAE wrench works just fine.

I def. use alot of PB blaster, T-9, antisieze. I have sockets, gear wrenches, offset wrenches 1 or 2 metric flare wrenches, a few air tools and a compressor, The oil cooler hoses are BIG. Those sizes of wrenches I don't have.

Rob,
Pete is correct. A 1 1/16 American open end will do the trick. (I bought mine from a local Ace Hardware for $10) Take a 22mm open end to hold the oil cooler fitting and have at it. I just did this exercise. One night of heating and coercing the fitting and two nights of PB blaster and SLOWLY turning the fitting back and forth while squirting more PB blaster. Both fittings were tight as the devil to start out and are smooth as butter now. No threads damaged. Whew! I proved to myself that the removal of the fittings can be done without destroying the threads. If you are unfortunate enough to damage threads, do a search on this board on "Kmetz". Or go here: http://diesel.list.archives.mbz.org/2002/Sep/Vol_3_Num_2161/ He has a great write up on replacing the oil cooler fittings with $4 parts from MB. Good luck! Tom

I still have the tap from when I replaced the fittings on the cooler in my 116. I bought it for $30 something but it's yours for $15 shipped. It's only been used once.
Thanks David

Ah, gear wrenches, how they would have made thou job easier.....I have none, so it took forever to do some of those areas. I also had no problem using the standard huge craftsman 27mm wrench to fasten the fittings, both at the cooler and at the oil filter housing. Gear wrenches I am definatley going to get sometime, once I have money again...
For my job I got: 3 ton jack + stands (all tools are craftsman) New metric wrench set (2mm-19mm) tons of extensions in 3/8 drive and some 1/2 drive sockets (big ones) a 27mm wrench a lot of dremel cutting wheels a new oil cooler off ebay (mine passed away upon removal) a big plastic tub to catch oil and penetrant runoff/spills a new 3/8 wratchet, old one had died on previous project..... a universal joint....never really used it though the new OEM motor mounts.... some new bolts for the motor mounts....some were very corroded the new OEM cooler lines Seafoam penetrant PB Blaster Penetrant Engine Degreaser/Cleaner Brake Cleaner One Billion Shop Rags.... 1.5 quarts of extra Shell Rotella T to make up for oil lost in lines/cooler... total spent: around $900 hours: ~18 Dealer cost to do same job: $1600-1800 Doing it yourself and figuring it out as you go? Priceless

For the oil cooler lines, i whacked 4" off the handle of a cheap 12"crescent wrench so I could get a good swing between the OF housing and the inner fender liner. Worked great.

On my oil cooler lines, I made a 1 1/16 flare nut wrench by cutting an inexpensive wrench with a Dremel tool. Worked great and it still works as a box end if I need it.

This is similar to my wrench and should work fine if the line nuts are not too tight. The problem is, once you cut the circle of a box end wrench you weaken it and it will splay out when some serious torque is applied. I spent some time reinforcing the outer circle of the box end by welding tool steel to it and heating, grinding and quenching and such. Then I carefully ground it to a nice "precision" looking shape so it wouldn't look so ugly. A 12 point "Crow's foot" would be another idea for this type of tool.
