Could it be the water pump ?

Car is fitted with Fluidyne radiator, and TRD low temp stat. Under normal running conditions i.e. on the move the car runs at around 80-82 degrees, however when stood in traffic the temp rises gradually up to 90-100 over about 10-15minutes. Once on the go again the temp drops again, could it be the water pump on its way out ?. does the water pump suffer from wear out ?.

 

Any help much appreciated.

The dash gauge is "fiddled" to look like it stays rock solid, so that Joe Punter doesn't freak out and the car looks 'reliable'. Really, though, the coolant fluctuates across about 20degC of temperature like you are now discovering.
