Did they check for evidence of coolant in the oil? Did they do a pressure test?

Well, the dye test was performed about 6 months ago and nothing was found. I have a feeling this is going to be a costly fix. I did take it to a different GM dealership (different from where we bought it) to see what they find. I do have some condensation coming from the exhaust, but nothing major. I hate this truck, if we wern't so up side down in it, I would get rid of it. Well I will keep everyone post, it is at the garage as we speak....

Get a bottle of Bar's radiator leak fix from auto part store like AutoZone.
 
I did for mine as I had the said coolant leak, which is quite well explained in this forum under coolant leak.
 
It seems like there indeed is a major problem with engine heads with porosity leaks, which GM of course denies. After overheating my engine and pouring almost 2 gallons of antifreeze in it I found the coolant leak topic and there it was. I immediately got the Bar's leak fix and first it seemed to totally correct the issue. Later I learned that a leak still exists as I was still loosing coolant but very little compared to what happened first.
 
Read under the correct topic, it is all there.

even tho my tahoe wasn't dropping fluids, the shop said it needed a new w/pump. with 83 k miles I relented cause I didnt want to break down somewhere that might reqjuire a tow. Was also told I needed some brake work. I expected to need new pads with 83 k miles. But do I need new rotors as well. How about just turning them? thnks/dc

Did you ask them what led them to decide the w/p was bad?
 
Unless the rotors are warped, scored heavily, or below minimum thickness, they shouldn't require turning.

Thanks shark, they said there was some seepage around the w/p and the
reservoir needed to be topped off. But frankly one could pour a couple inches into it everytime you lifted the hood. And no they didnt say the rotors were warped, or scored. Only that the rear pads were worned down. Im surprised that the front pads werent worn instead of the back ones. I think my shop might have stung me. Its to bad, I used to think they were good guys.

Typically the rear pads wear at about 2/3s the rate of the fronts. I'm guessing that they are probably the original pads.
 
If you have to add two inches to the recovery tank often, then you are losing coolant someplace besides seepage at the w/p. Did they do a pressure test?

Yes, they say a pressure test was done. I cant argue with them.
But my truck never got hot. Not even once,now I have a new
w/p as well as new pads and new rotors on the rear. I've heard
that if you get 83k miles out of your brakes, you should be
happy but today a guy told me he didn't need them until he
had 143k miles. I do a lot of city driving and I understand
the demand that puts on a truck. My wallet is a lot lighter too!
thanks for your advice Shark, I apprec it.

They said they were just worn down to the point that they couldn't be turned. I asked (based on my experience from the cars I had when I was a kid) then
why didnt it shake & shimmy. Their response was because they were only
worn down, not warped. This shop has a rep for being honest but several years
ago they were bought by some larger company and maybe the "neighborhood
shop" mentality is gone. BTW could the w/p seep fluid for a long time before
finally failing or is it a sudden death event?
thnks again./dc
