bill's given a good check list.

a missing shroud is the likely problem. very important to the efficiency.

if the gauge is showing hotter when climbing or working hard, that's appropriate. the temp will show a bit higher even with the fan running sometimes. it will cycle up and down within a range that you will soon recognize. the fan must be able to bring down the temperature from the higher readings when working hard and back to 'normal' when idling or cruising. if the gauge is not going into the red area and it does not stay elevated, then you may be ok as is. keep a close watch.
