heres the scenerio hondapower: your driving down the road, with the a/c on and the condenser fan is not working. this causes your engine temp to go up slightly since the additional cooling needed for the a/c condenser is not available. you park the car and shut down, the temp sensor senses the slightly higher temp and runs the main fan for a few minutes to lower the temp. that is why i suggested to check both fans the easy way, by turning on the a/c. i can see where i may have caused some confusion by saying "if you dont have ac." i agree the fans are controlled independently by the a/c and engine temp, but i disagree when you say the condenser fan exclusively cools the condenser and the main fan exclusively cools the engine coolant. both fans pull air through both the condenser and the radiator, thus providing cooling for both systems when the a/c is used. they work together to fight the higher temp imposed by the condenser when the a/c is running. a bad condenser fan will cause the main fan to work overtime once the engine has been shut down, again, when the a/c is used. this has happened on both my and my parents honda. heres another tip: when you pick up a fan at the junkyard, check the endplay of the motor shaft by pulling on the fan blades forward and back a bit, a motor with alot of time on it will have excessive endplay, usually 3/8 to 1/4 inch. a new fan has virtually no endplay. so if you have your pick, pick a fan motor with the least endplay they have, it will last longer.
