06LBZ · 03-21-2007, 07:43 PM

both of my trans oil cooler lines are leaking where the tubes come out of the radiator and crimp onto hose. curious if anyone else is experiencing this. gotta love it. i checked one other and it was leaking. mines an 06 with 13000 miles.

I put a set of cooler lines on an '06 K3500 last week. The lines are fairly easy to replace.

Gm has long had trouble with these stupid crimped aluminum fittings and i really wish they would find a better line to use on the trucks!

They used that style line for oil coolers on the 4x4 S-10 trucks & Blazers. Every one of them has leaking oil cooler lines. They need to find a better way to crimp the line.
