Replaced oil cooler seal

[92EcoDiesel Jetta]

I used this Gear wrench setup that is about 8.5" long, with the ground flat face socket and working blind from above, had a hard time keeping the socket aligned with the nut so it doesn't slip. There was also very little swing room for the gear wrench. I don't think there is room enough to swing a 3/8 drive torque wrench (much longer than 8.5") in the engine compartment. Maybe it is possible with a long extension + universal from under the car but then you'd need a helper- one to hold the socket on the nut and the other to turn the torque wrench.

I think a stubby 1/2 drive or  3/8 (even shorter) ratchet from above is the best tool for the job. Just tighten to 18 ft lbs by feel.

Is the tube and nut discontinued? Is yours messed up. Check the dealer if still available items 17 & 15.

naw i can find parts/nut, thanks though, what i meant was  27mm nuts and bolts for specialty tools, 1 bolt+nut for trans timing tool, +2nuts to take down tube.

WTH ARE YOU TALKING ABOUT? ? ?  Don't answer unless it has something to do with changing the seal.

27mm is 1 1/16 basically. Vise grips are the specialty tool for this job. Just don't grab the threads.

You should able to get that off with a standard 27mm socket.  It just has to be squared to the oil cooler because of how slim the nut is. Get the socket on the nut by hand so you know its on there, and then put the ratchet on and take it off. 
   If not, yeah channel locks would probably do the trick

Yes, 1-1/16 is 0.0125 smaller than 27 mm, with tolerance in manufacturing, they are practically identical. The socket and gear wrench in the pic is from Lowes/ Kobalt brand I got for $1.00 and $5.00 when they changed to a new line of tools and clearing out the old line.

Do you know if a 6 point impact socket (thicker wall) will fit the nut (is nut recessed)? I did not try one but a six point is less likely to slip off the nut.

It's pretty flat on the bottom, an impact socket should work fine.

Sounds good. Were you able fit a torque wrench in there?

I've driven it a bit and no more drips down the oil filter.
