P.S. I thought I should mention that you don't need any special tools to do this job. Believe it or not, the best tool for the job was a small (6 inch) crescent wrench. There is very little space to unbolt the lines at the oil cooler, so the small crescent wrench worked very well. A regular open-end wrench would have been too long (and a 22mm wrench would have required a special trip to Sears).

The only other thing you need is a very thin wrench to fit on the oil cooler boss. My full size crafstman wrenches were too thick to fit on there (there isn't much space inbetween the oil cooler and the nut on the oil cooler line), but I had a cheapie, no-name standard size wrench which was very thin. I think it was 15/16 or 11/16. I also had some very long 1/4 inch extentions which helped remove the bolts holding the lines to the brackets.

Good luck,

Greg
