Maybe I need to get a new set of belts on it. Thanks!
Not sure about the noise, worth checking all the pulley's and tentioners.
However, your temp gauge readings would have me worried. Both of my Foci (a MKI and a MKIII) have never went above the half way point. Even in 105°F heat, stop n go on the freeway, idling for hours... That needle never budges.
I would at minimum replace your thermostat. I didn't see your mileage, maybe its due anyway? Not sure if there is a way to check your water pump without removing it... and if you go to the trouble of pulling it off you might as well replace it. But that would be the last thing on my list to do.
