alistair '86 syncro 7 passenger '82 westy, diesel converted to gas in '94 http://www.members.shaw.ca/albell/ http://shufti.wordpress.com On 22-Apr-10, at 7:14 PM, Tobias Gogolin wrote: I suppose the most important purge point on my '84 is the one in front on top of the radiator (are there others?). I would have to get a hose nipple with 90 degrees that fits there or cut back the bracket thats obstructing above the screw! I don't know, would be interesting to measure the pressure in the cooling system! Maybe a simple over pressure relieve valve could purge but that would be when its already overheating, and then its not going to have enough water to work properly either. So maybe better would be some kind of flotation valve that purges if there is no liquid? To simply run a hose back to the tail may result in the same problem that I'm trying to solve which is if water gets into that hose it will probably air lock! Today I did another short test drive after purging at a nose down slope and I still have the same problem that had already disappeared in test drives last week, what i'm talking about is that a few seconds after starting the van the light begins to flash in the instrument rises quickly to max.! I wonder what this is now! Maybe the oil in the coolant is making the level sensor think, lack of water? Since no water gets into the oil (yet) i'm still putting of that costly repair of those head gaskets that Scott kindly has explained about! And yes I love my Vanagon, its suspension is great and its a very comfortable car! Just cant wait to convert it to electric power! Lord let it rain $$$ ! |
