Car running hot during emissions test

Hi All,



My brother is looking at buying a Rover 200, but it mentions:



The car was running hot during the emissions test which the garage presumed to be the Head Gasket



Would that be a likely cause?

My thoughts are it could be the Rad fan isn't working so caused the car to overheat slightly when idling, or possibly a dodgy thermostat?



Apparently there is also the advisories:

Slight seepage from power steering rack

and

oil mist to shock absorber



The first one, I'm guessing is a straight forward leak, but not sure what that would involve, the second one doesn't mean a great deal to me other than there was a small bit of oil found around the shock absorber?



Any advice/help would be grand guys :)
