A problem just crept up on my 91 cruiser. The temp gauge creeps up to a little below red then drops while sitting in gear. The funny thing is that it shows no under hood symptoms of being overly hot. The fan clutch even dropped in rpm once when it showed over mid point. I don't think it is the clutch because it seems to be moving a lot of air. I am thinking it was my low budget repair of the bypass hoses with unformed hose that is somewhat kinked. Would this cause excessive heat around the temp. sensor and give false readings? I have a new radiator as well, so that is not an issue.
