I spoke to Stephan about the van - it seems that pretty much all the air conditioning hoses are rotting away. Basically as they replaced a couple, leaks sprung in other (28 year old) hoses. I just said screw it and told him to replace them all... everything should be new then. Oh, and I asked him to look at the wheel bearing that's been leaking grease for ages (after being overtightened when it was installed). Might as well have nothing on my squawk list when I get it back, eh?
