Are serpentine belt water pumps \"reverse rotation\"? My water pump took a crap and I replaced it. The new pump says that it is a reverse rotation pump. Is this true? I ask this because since changing the pump, the temp gauge has not gone above 100 degrees. The sending unit is good and the wire is hooked up. The "hot" air coming out of the heater vent is warm at best and there is enough anti-freeze in the radiator. Could the thermostat be stuck open?? <a target="_blank" href=http://www.moabdadc22.alloffroad.com/>http://www.moabdadc22.alloffroad.com/</a>Real four wheelers don't need tools to remove body panels, paint, tail lights..etc.
