Cooling lines

[Lund]

Replacing tranny cooling lines and quick connects. 4l60e on 06,5.3 4x4. Anyone know or where I can find torque specs on connectors to tranny and rad?

Don't torque them to be honest. The transmission case is aluminum so it doesn't need to be very tight and the radiators can strip/crack if just because they want to.

 

Snug them down and call it good, I never have them leak.

I think around 80inch pounds not sure. Using Dorman lines. Can u reuse the old clips or use new Dorman ones if not changing quick connectors? Another site for 4l60 says 28ft lbs but that seems like a lot

You can reuse the clips as long as you didn't deform them taking the lines loose

Look at All Data or cal lyour local dealer; congrats on using a torque wrench; you can bet your bottom dollar there is a spec for that and everything else on your truck.
