Hi Listers,

        Even with  the van is not running I find a drop of coolant on the lower part of the connector between the rear heater core and the valve.  I’m aft rain to tighten the two bolts any more.  I am strongly considering purchasing a new valve from van cafe as well as a new o ring.  Hell for the price I’m almost considering getting the whole new kit as i can get the core, valve and ring for less then $1200.00 and I payed $94.00 just for the core at Bus Depot!  Now that I can finally read some of the vender sites using screen readers I hope to make better choices in parts selection! 

        If anyone has a tip about preventing this drip please share.  Otherwise I will drop some more bucks and try to solve the problem with a new valve and o ring. 

Interestingly, before doing the heater core exchange I also noticed this spot was dripping coolant but I assumed just the o ring had given out or the connection was a bit loosened due to my moving it around. 

Quick tips or advice welcome!
