I don't have huge metric wrenches here@ home, and my shop is locked up for the weekend. the fitting on the oil cooler itself is a hair bigger than 13/16 and the size of the line is a bit over 1" anyone know offhand? or care to go outside and look? by the way this is for the oil cooler that sits under the radiaror..



Thanks

 

on a 2nd gen it was 23mm socket

 

narrow 21 and a 26 wrench

 

For the stock SE lines it's a 22mm for the front and a 23mm for the rear.
