Your thermostat may be sticking or you have some obstruction in your radiator. If the fans are coming on then your engine should cool, unless the water is not flowing properly, which would point to a thermostat or a bad radiator. Here's an article which shows you step-by-step how to replace both: http://www.shareyourrepair.com/2014/12/how-to-replace- radiator-on-2004-2007-toyota-sienna.html
