the guy i bought the ZT off had a load of work done at a rover specialist, head skim and gasket plus a refresh on the coolant system. its running at 80-85 degrees round town and on the motorway. creeps up to around 95 after idling for a while. seams a bit cool to me ? my last 1.8 sat around 90-95.
does the turbo run a bit cooler ? or have they fitted the wrong thermostat
