Hi all
Got an unusual problem on my P38 4.6 at the mo. Every so often the temperature gauge climbs right to the top of the normal range. It can happen if I'm doing a steady 40mph or so not really loading the engine, sat still in traffic, or climbing long hills on the motorway at 75mph or so. Other trips it'll never move from the normal running temp.
It seems to have started when one of the pipes that takes the water to the gas vaporiser broke off when we were towing the caravan on the motorway. The temp gauge went straight into the red and the over-heat light came on. Needless to say I got it onto the hard shoulder as soon as possible & got the RAC out.
I've been mooching around under the bonnet and I can't see anything wrong on the outside. It doesn't seem to be using any water, or if it is it very very little. It is using a bit of oil, but I keep putting a drop in now and then. Thing I've noticed is that the alternator is too hot to touch after a short run - is this normal?
Any ideas where I go with this would be gratefully received!
Many thanks
Marcus
