How many cooling fans should there be in an Oldsmobile Silhouette V6 3800 engine - it is suggested in the manual that there should be two but it has only one?

Yes, the Manual is correct, there should be 2 cooling fans on the 3.8 and 3.4 engines, but the 3.8 engine has a fan on EACH SIDE of the radiator...one pushing air from the outside and one pulling air from the inside. Each fan has its own thermostat and different engage/disengage points. One fan unit should operate the engine OK for all but the most extreme con- ditions..ie.. A/C on in the summertime..keep watching the engine Heat Gauge if it goes higher than 200 degrees, make sure there is a second fan. Salvage yards should have good used fans available for this engine with mounting brackets..just wire it in parallel with the existing fan, or have a mechanic locate the original wires and make sure the second thermo- stat works correctly.
