Flush and change the coolant every two years regardless of miles driven. That is all. -----Original Message----- From: Vanagon Mailing List [mailto:vanagon@gerry.vanagon.com] On Behalf Of Mike Sent: Thursday, October 14, 2010 5:32 PM To: vanagon@GERRY.VANAGON.COM Subject: Re: Stainless Coolant Pipes Endanger Engines the sky is falling! fear-mongering. Bull. But if you're really concerned; Coat the pipes inside and out with black POR-15........ Solder on braided bonding straps; bond everything to chassis ground - no potential, no current flow. next subject..............
