Hi there. I own a 1997 Chevrolet Blazer LT 4x4. Just hours ago, I started my Blazer to warm it up as it is very cold where I am located. Normally the heat blows as hot as you can imagine, but once I entered the car it was blowing cold air. Also, I noticed the temperature gauge was considerably higher than normal. I did think there was a problem but I had to leave because I was running late. As I continued driving, I noticed the temperature gauge was fluctuating between considerably hot to cold. When I returned home, I noticed a puddle of some fluid under where my car was parked. I popped the hood and noticed a faint burning smell. When I checked under the hood, I noticed under the area where the radiator is located was wet, as if something was leaking. Any ideas of what this could be? Thanks.

 

Did you check your antifreeze to see temp its good down to????? Sounds like fluid froze??
