As for the valve in the engine room on the heater hoses I think they suck! I am planning on going to the junk yard and finding one off of an astro safari. WE have 94 safari that has a really neat water shut off valve. Instead of just blocking off the water it has a bypass tube that just sends the water around the heater core. The van that it is on the air conditioner doesent work but when that valve is closed you dont get any heat from the heater core but in the winter when it opens be prepared to be roasted. Be forewarned you have to go to either a junk yard or the dealer. Not avaliable at part stores. If you want one Go to the junk yard pop the hood on the van and look at the a/c box. It looks similar to our boxes. If you have found the right year there should be a plastic valve that looks like an H with a vacum actuator on top. Hope this helps.
