What is the clear liquid not water leaking from the bottom of your 2001 Chevy Suburbans Engine?
You engine contains coolant, oil, transmission fluid, P/S fluid, brake fluid, gasoline, & windshield washer fluid. Smell of the fluid, and if it has no smell it is not gasoline. If it is not slick to the touch it is not oil, transmission fluid, or P/S fluid. So that leaves brake fluid, or windshield washer fluid. Brake fluid does have a slight smell, and may be slightly slick, if you pay close attention. Look at the area it is coming from and this is a clue to what is leaking. Try laying a piece of white paper under the vehicle and see what it looks like on paper. Color is a clue.
