[s-cars] Coolant loss / Use

[Ian Duff]

Bet you need to replace the plastic nipple at the back of the block,  
below the head and above the bell housing, into which the cooling hose  
goes. May be other cooling bits failing, but that'd be my first point  
to check. While you're at it, addressing the weeping at the t-stat is  
pretty easy, and a good time to replace the t-stat.
