Oil cooler hose top 280SL

[Bob G ✝︎]

Ok I got my new high preasure oil line hose from Tom at Caliber motors. That certainly lighten my wallet. The nut size 22 Millimeter the question I have is I noted that a nut where the hose meets the oil pipe line and is threaded on. Seems like a tight fit to get anything but a snubby wrench in that access area . To undo and tighten this new hose. I have been told that it is important to have two wrenches one to hold the nut that is fused to the oil pipe and one to tighten the loose 27mm nut to the new union.

Can some one help me with this proceeder. the top of the oil preasure line comes free with on problem it is the bottom that I need to now how to untighted and tighten correctly so as to not cause any damage to the oil line pipe.

What are the proceeders and tools nessessary for this proceeder?

Thank you
Bob Geco

Hello Bob,
These are always tough, not very much room. There are a lot of tool combinations that could work. You should have no trouble holding the 27mm fittings at the end of the rubber hoses with a standard wrench.  The smaller 22mm fitting on the metal line will want to slip with a standard wrench. A "line wrench" will hold usually.  Smaller line wrenches are commonly used for metal brake lines. Larger size "line wrenches" will be a little difficult to locate. Probably not a Sears item. I use a "crows foot line wrench". I can hook different handles to it to make it work. (see pic)

A standard 22mm line wrench along with the standard 27mm works best on the lower oil hose, from below. An extra pair of hands helps.
I am sure that some other combinations will work also (short wrenches, vicegrips, angled wrenches etc. ?)
