      I think its designed to stop the fan at a certain time when you turn off the car and it is too hot.

              All my switches on my fans are bad so I just have them kicking all the time now. Its on my list of things to fix, the best advice I can give to locate the switches is get a wire schmatic from a manual and locate them.

                Are both fans turning on when it reaches that high or just 1 fan. Your symptoms sound like the condenser fan is coming on. Because you recently engine swapped, did you verify the main fan is plugged into the harness?

                    One fan is automatic from the temp sensor on the top rad hose i think or the one by the thermostat

                    the Condenser fan comes on with the A/C Switch
                    H22A, Short Ram, AEM Uego, Chipped P28 with Crome, A/C Delete, Rear disc conversion. (Front Tein Basic Coilovers, H&R springs 1.7/1.5, and Fog lights waiting to be installed.)

                      Fan timer is activated by coolant temp "switch b". (the switch is activated @ ~228F). It turns on both fans. The gauge inside the car gets the info from the temp sender. Sounds like the "switch a" is bad.

                        The fan switch that kicks the radiator fan on is on the thermostat housing, located down and in front of the throttle body. The sensor has a brass body w/ green or purple plastic, also aims towards the front of the car. You can always jump the 2 wires together w/ a paper clip to jump the fan(s) if you have to.

                            Good, but since your swap, you might want to have your ECU checked to see what temperature it has programmed to it. What ECU are you running?
