Any help would be great! Okay, So I drive a 2001 2wd V6 Blazer..It has 150,000 miles on it. A few days ago after driving an hour home, There was a boiling noise coming from my engine, I think it was the coolant. I kept an eye on it and it began leaking coolant after this. It is leaking out by my front rear passenger tire, I checked all the hoses are fine and no cracks in my radiator so I assume that there is a crack in my Coolant case (Not sure if thats the correct term, just what you pour the coolant into) I ordered a new one and it will be in tuesday. Also, with this a white fog has began spilling out of my A/c vents, even with just the fan on. It fogs up my windshield, even with the windows down..Anyone have any ideas?

 

Sounds like lower intake gaskets. Very common issue. It will take about a day to a weekend to repair and make sure you get the felpro gaskets. Do not keep driving it.

 

what are the common signs of this and how much money am I looking at dropping?

 

i'd take a good look just in case, coolant reservoirs gone bad can cause the leak, but you could be leaking from your heater core. make sure your floor is dry, and take a good look for leaks. if its not smoking out the hood, and drives fine, i'd suspect heater core. expensive to replace, but to do it yourself won't cost much
