Thanks for posting this Chris. It's always useful to remind members of this (as well as correct operation of the cooling fan) before the subject of head gasket failure rears its ugly head.

Sometimes however, it's just the two 'O' ring seals mounted on the expansion tank cap which flatten. They're not available separately from X-Part but something suitable can be obtained cheaply.
