first thing I would do is change the coolant temp sensor that's what turns the fan on at 222-226 degrees.it's only like 10 and most likely ur problem.when u replace ur sensor make sure u check the connector to it if it's corroded then u will have to replace it too they usually turn green when they corrod.make sure the engine is cold when u change it.u will also loose coolant.make sure u get a brass tipped sensor the plastic tipped ones crack.let me know what u find.
