Hi all
Notice coolant drop hang on gerbox where it meets the engine ( clutch area) and few on the ground. Looking for the small leak a few month but newer seen it is there. My express 1998 with 43000 only.
Was checking top of the engine also, dry. Replace water pump, dry now.
What can be leaking there? I heard there is a frost cup which can be rusty and may leak...
Cheers

 

Small block chev's have two frost plugs on the back of the block behind the flywheel.....god knows why. 351 ford small block doesn't have them.
If they are weeping, then you will have to live with it, or try one of those stop leak kits......which can cause more problems than they fix....lol.
Could also be from a coolant sensor, or maybe the intake gasket....
