so are these cooler lines for the tranny or the engine. And i dont know much about the 6.5s more of a 350 and cummins guy but i thought that only auto trannys had oil coolers and manual trannys didnt.

 

Nope, your truck aslo has engine oil cooler lines, you need to search for a kit, the stock lines have these crappy quick connect fitting that fail very often, better get them fixed quick, they can drain your oil out fast when the finally let go!

 

Thanks yall i will try and look at her if i make it home this weekend.

 

NP, let us know what you find....

 

Oil cooler runs driver side of block aluminum/rubber, notorious for weeping at the crimps, sucky design, besdie known leakages, more than (1) 6.5 has died a terrible death when wire clips holding in place rot and lines let go, and you dump all your oil very fast., trans cooler if you have auto trans runs the passenger side.
