my own xr3 turbo runs at 85'c most of the time
i replaced the standard fan with a 12" flat type , much better cooling now , but then again , we have temps up to 35'c in summer
my car does not like running hard in these temps , prefers the cooler nights

try running some rad cleaner for 100km and them flush with a garden hose , this job is a lot easier with the rad out.you should see plenty of muck flush out , this stuff clogs up your rad and leads to increased running temps
