Although its never really run warm, my Puma seems to never run at what I would call optimum temp (according to the temp gauge in car). Heaters do get warm but not as warm as you might expect. Coolant is clean but car does use a little oil (this might not be related though). Took it down to Cornwall last week and on the motorway it never really got above the 'n' of normal.
Common problem? Simple issue?
