Oil cooler line & trans cooler line replacement

[domoarigato]

@domoarigato @992dr How hard was it for you guys to change these lines? Noticed some droplets on the driveway this morning towards the front of the vehicle and I think I may have to replace these lines as I had noted some seepage when I first picked up the truck.

It wasnt bad at all like @992dr stated. I did it while I did my oil change to minimize the amount of oil that leaked out.

My replacement lines from AC Delco did not come with the quick disconnect retainer c-clips so be careful when you remove yours because you will have to re-use them.

The only bad part (which wasnt that bad), was fishing the oil line out / in. It helps if you have another set of hands but I managed with myself.

It also helps to unbolt a few of the undertrays to give you some more room to work with.

It's that time of the month for a few of us evidently, my trans cooler lines are seeping enough to leave about a 2" wet spot overnight.

I still need to do my trans lines. They seem to be a little more harder to access than the oil lines. Let us know how it goes.

@992dr @domoarigato @RichardCranium Thanks for the insight and replies. Did a bit of research on some other forums and some guys have said that adding some additional clamps might help. From your observations do you think it would?

 

[992dr]

Yes, I removed both trays helps a bunch, it really opens things up.

Fishing the lines through was a little tricky but like Jake said, its not that bad. I also did this by myself, it wasn't too bad. Just be patient and it'll all fall into place.

Hmm, not quite sure what you mean by additional clamps? What would you need additional clamps for?
To hold the lines after they were installed?

Adding the clamp would stop the seeping. That's what some people were suggesting.

I'm going to put the truck on my ramps tomorrow and take a look and see if the above fix is viable. Shouldn't cost too much in the grand scheme of things too.

Do you have any picture of the clamp and where it is affixed to?
I have not heard of this method to eliminate the seeping.
Thanks

@992dr I saw this particular post. Didn't get a chance to look under the truck today. Will do so tomorrow. The dripping has stopped though.

I'll have to take look under y Tahoe this weekend.
I'm trying to picture what he's saying but am having a hard time trying to picture it. Maybe when I take a look I'll be able to get a better idea.
