Dont overheat this engine, it is compeletly alluminum and you will have costly repairs if you really overheat bad. I think it is your electric cooling fan is shot. Check the wire connection on the fan in front of Rad. Then run engine to normal operating temp. according to your gauge and use a test light to monitor wether there is power to one of the wires going to the fan. Be patient but dont let it overheat. If you have power and no fan, replace fan. If no power go to owners manual and check fuse first and replace. If fuse is ok then find relay and repace. Of course Im assuming that your wiring to the fan is in good condition to begin with.
