e250 fan blowing hot air onto the engine

1990 e250 6 cyl. 4.9L van.

Problem: the fan is blowing hot air (from the radiator) back onto the engine causing the engine's air space under the cowl to heat up (though the engine is not overheating) and causing what seemslike a failure of the oxygen sensor, because the vehicle then runs poorly, especially when I turn off the engine for a short period then restart it (like when buying gas).

I have recently replaced the oxygen sensor, the temperature sensor (in the water circulation system) and the radiator. The old radiator was in bad shape and really needed replacing but the heating problem persists.

The only thing that helps right now is to drive with the cowl removed, which allows the hot air to blow away (and onto any unlucky person in the passanger seat).

Any suggestions (other that replacing the vehicle)?
