Could you expand on the cooling system differences just a little? Apparently my experience with early water cooled gas and diesel VW motors is not typical of later generation versions. What things did they do to improve them and how much of those improvements can be retrofitted to the earlier motors? My first experiences were with what I think were 1.7 liter motors, so that's getting back there. Thanks, John Wakefield >> Basically the pump is redesigned and the system can purge the air from the heads and block through that loop around the engine compartment. System is more tolarant of air and some combustion gases getting into system. Also, there is the water to oil oil cooler that lowers th oil temp somewhat. Works good at 60 mph and lower.
