I have been lurking and reading about the overheating problems. Something tells
me the Jag engineers might not have had Austin in mind when they put only one
temperature sensor on the passenger side.

Seems .. not seems .. it happens that you could actually overheat the drivers
side head and the gauge not show it. Just got through looking at a head with
dropped seat.

I am new to Jag .. but this seems to be a hell of a dilemna. Do some of you
guys
install auxiliary sensors and gauges for the drivers side ?
