Question about 2002 Toyota Highlander
One fan is the a/c fan and the other is the coolant fan.if the smoke is from a bad head gasket and the engine is using coolant,the lack of pressure could be causing the coolant temperature switch not to come on.and the cooling fan will not work.that is if it is a dual electric fan set up.if the main fan is a clutch fan,it is electrically operated a little different.some products are known for intake and head gasket problems and the only way is to pressure test the system.was the gas cap replaced because of an evap code? excess water vapor leaking back into the intake manifold could trigger an evap code and fool alot of people into thinking it is in the evap/purge circuit.
