Temperature gauge help!

- 1992 YJ 6 Cyl
My temp gauge isn't functioning correctly. On a cold start the gauge acts properly and the needle climbs as the engine warms up. But for some odd reason it stops at around 160. If it's a hot day and I'm riding higher rpms it will slide up to 170.(I imagine this being similar to riding at 210 and it getting hotter to 215-220 ish.) Unless I have some sort of supercooled jeep I'm positive this isn't correct! I replaced the Temp Sending unit on the back of the head. No results. Any ideas before i continue to replace things that aren't broken?
Thanks

gauges are known to get dirty, remove the gauges there is yellow plastic matterial with circuits to it, circut board i guess lol

anyways get sand paper very lightly and i mean lightly sand the female connection then the male connector to the circuit bored, also remove the black plastic piece by the temp gauge and clean with rubbing alcohol that should do the trick, worked for me. if not you should consider jcwhitney.com they have nice digital gauges im thinking of getting
