Just got a 95 4x4, 4.3L. Blazer. First off I will mention that I need to replace the brake booster and master cylinder. But the issue is: been seeing small puddles in the morning after the truck sits overnight. But, none of the fluids seem to be going down at all, yet the fluid has a light brown tinge to it. Not sure if water picking up the rust from underneath or is a leak. By the front driver's side and in the middle seem to be where wet spots are. Any thoughts?

 

Think I found the leaks...very small trans leak and a power steering leak. Put stop leak in and puddles decreased a huge amount. Also going to do a trans oil and filter change.

 

Just my two cents but I wouldn't rely on them stop leak jobbies. Just a bandaid that'll fail you when you really need it in my experience.
