Just got back in from moving the A/C compressor out of the way. As Robert, Terry and others pointed out, it wasn't the oil cooler hose. I thought it was, because I was looking at the ETKA diagram, and it basically shows everything on the same level (Note to self - Never assume...). The hose that broke is the coolant line from the left cylinder head to the coolant manifold - the strange one that has a 90 degree bend, and changes size about three times. P/N is 025 121 058M. It split right were it goes into the head. A new one is on order from Bus Depot. After I install it, I'm going to pressure test the cooling system to make sure that all is well. Guess I'll have to go buy another few gallons of coolant...<sigh> Don in Reidsville, NC 1986 Kawasaki Concours 1988 Vanagon GL (Sylvia) "I reject your reality and substitute my own." - Adam Savage ----- Original Message ----- From: "Robert Cardo" <rrecardo@WEBTV.NET> To: <vanagon@GERRY.VANAGON.COM> Sent: Fri 29 April 2005 01:14 Subject: Re: Coolant leak below A/C compressor
