So can someone tell me, is leaking from the under side of these is common/possible? I came outside this evening to a drip from the back of the van. 

Inspection revealed drip directly above the coolant bottle bracket. (Underside of bottle ) I could not flip the bottle over or enough to see under it after I took the retaining screws off. Coolant hoses seem dry, cap seem dry.  Seems to leak under pressure. Drip drip drip. 

Thanks 
Tony
