My new 95 DC2 I just bought I also thought was running a little cold. Rarely moved off the Cold initial line. So when I took it to my mechanic to do the usual used car purchase of changing all fluids, I got him to put a new Honda OEM Thermostat and Gasket for it.
Now she sits nicely at 40% which seems alot more realistic.
Can't comment on whether the car 'feels completely' different though :) Maybe mine wasnt in bad condition as some others on here. I did it more for peace of mind.
