popped the hood and noticed a little bit of seepage/moisture coming from what appears to be trans cooler lines? Behind the driver side fan.




This a common thing on these trucks (2012 silverado 1500 5.3)? Was thinking about picking up the trucool trans cooler. Would the lines that come with it replace these lines?

Truck has 70k miles on it. I bought it with 40k and drive it pretty hard. Was going to do a trans fluid service on it, but would wait until I get these lines fixed.

I also saw that my ps reservoir seemed to have some fluid around the cap. Not as concerned about that though.

Thanks

Unless they came out with something new, the lines that come with them are like 3 foot long tops so doubt it. Most guys go with an -6 an hose and replace it all the way to the trans, will run you about ~150 bucks on summit with an ends and all.

Those look like the oil cooler lines. The trans lines are in the top of the picture.

And trans lines are way longer than 3 ft.

Trans lines are like 3/8" diameter on the solid line portion and the oil cooler lines are close to 1/2"

Sorry, was referring to the rubber hose that comes with the Trucool 40k. It's like 3 feet

Yup definitely oil cooler lines

common problem on these trucks? should I swap out with another factory set of lines, or is there another aftermarket set that's better?

Yes they are a common problem. Make sure your radiator isn't weeping around the built in oil cooler as well. Go with GM replacements on these. I have had aftermarket and GM replacements and the GM replacements are better.

Like he said, stick w/ the GM lines!
