I noticed my truck smelled like antifreeze yesterday when I came home from work. This morning I had a puddle of it under my truck. Tonight I noticed that it seems to be leaking from somewhere right under my relocated throttle body. Almost looks like it is coming from the A/C. Any thoughts?

 

Pressure test the cooling system and use a blue LED flash light ( it will make the coolant glow) and pin point the sorce. You shouldnt be leaking coolant from the A/C.

 

its rare but it happens to most gmc trucks just take it to the dealer and theywill service it for you under warranty.

 

I'm so pissed off. I'm supposed to go to Dez first thing in the morning tomorrow for a tune.

 

Damn that sucks. I hope its nothing big thats leaking. Good luck!!!

 

just a shot in the dark, but maybe a heater hose coupling... its in the same general vicinity. mine decided to blow itself up this summer.

 

Thats an idea slow.8.

 

it was a small hose of some sort rubbing on the throttle body. easy fix, thank god

 

good to hear that bro. glad you got it fixed.
