i recently installed a new fuel pump. while in the shop, i was told that i have a tiny, little lower intake leak, they said it was nothing to worry about. this was about 2 weeks ago. today i drove home in the hot weather, (100 degrees) with ac on full blast. i later went out to the blazer to go to the store, and noticed a huge puddle under my blazer. is this coolant? i started it up and no leakage. then i drove it to the store with the ac on , and got out and it was leaking like crazy. what is going on here? no prior leakage. please help

by the way, i have heard that DEX COOL has rotted some hoses on other blazers. this is the reccommended coolant though. please help. thanks.

 

Never did it before, huh? Only when the a/c is on? Does it show up on the ground immediately behind the front passenger tire? Then it is the condensation from the a/c system and perfectly normal. We can't see the fluid from here so you'll have to determine if it is plain water, coolant, oil, or transmission fluid and where the liquid is originating from (as near as possible).

BTW, DexCool does not eat hoses.

 

My guess is A/C draining water from humidity. But as said above can't see it from here so I agree with above post completely.
