1998 Chevy Blazer 103000 (Antifreeze leak)

Lately my truck has been leaking antifreeze when its been sitting for couple hours. Also, usually when my truck is cold I hear a knocking sound but dont know where its coming from. All I know is that when the engine starts warming up the noise starts to fade. Anybody know a solution for any of these problems?

Hey nissan,
Sounds like a thorough inspection of the cooling system is in order. Remove the skid plate from underneath, clean the areas you see coolant and locate the leak. Some common areas on that vehicle are the water pump weep hole, bypass hoses, lower intake gaskets etc. Let us know!
