Hi All,

I've just (three days ago) bought a 406 HDi (90) GLX (X reg) to handle
my 100 mile round trip commute to work.  On the way to work there are
no problems, but on the return journey, about 10 miles from home, the
fan starts up and runs constantly at pretty high rate.

The engine temperature is running at just under 90 and apart from this
there are no other problems - water level in the rad is OK, and there
don't seem to be any split pipes so far as I can see from a cursory
glance.

Is it likely to be a thermostat problem or is there a common problem
with these cars that might be causing this.

One last thing, the journey to work starts quite hilly and then ends on
A roads all the way, obviously the return is the reverse and so the
hills are at the end of the journey.

Cheers for any answers

Toby
