Brilliant, will do.
In late August/Early September I had to replace my expansion tank cap and coolant level sensor at the same time because of deteriorated o-rings. If the ECT(?) sensor also has a similar rubber seal, I am certain it too has failed, and is the source of the problem. Will know for sure when I am under the hood this weekend.
