Just upgraded my 89 Laredo to an open cooling system. New radiator, cap (16psi), fan clutch, thermostat, hoses, and coolant bottle. Operating temp appears to be 215 according to the dash gauge. On the highway it creeps to about 220-225. My jeep always gets much warmer when going up long grades, or any incline where I really need to push it. However, I have a Renix engine monitor that reads the computer data. The water temp (different sender than dash gauge) says around 195. Am I overheating? I inspected the temp sending unit, the wire looks to be in not-so-good shape. Could this cause an inaccurate gauge reading? Will work on either repairing or finding a junkyard replacement to splice in.
