Some fans are pushers and some are pullers. Depending on where there is enough room to install the fan determinesthe direction of flow. In reality, the fan draws air across the radiator for cooling.

the engine fan is supposed to blow towards the engine. the fan sucks air thru the radiatoe and then blows over the engine to provide cooler air from outside. if the fan had to blow out thru the radiator, you would need one awful powerful fan to counteract the natural aid flow direction when driving

i had an electric fan on a 4x4 one time that was wired wrong. this fan blwe towards the radiator instead of drawing thru the radiator.this took us quite a while to figure out the fan was going the wrong direction.once the wires were switched, the over heating problems went away

1991 Mazda b2600i fan clutch does it suck or blow?

if it is on the engine side it sucks air through the radiator and toward the engine, a fan on the other side would blow but also would impede air flow through the rad.


What is a radiator for?

The radiator helps cool liquids that exits the engine. A tube at the top of the radiator flows the liquid into the radiator. Fans blow air into the radiator and cools this liquid. This liquid is then exited through the bottom of radiator and released back into the engine to be used. Radiator also holds coolant to to speed cooling process of liquid

What causes a head gasket on a car to blow?

Anything that causes the engine to run hot, like a faulty thermostat, can cause the head gasket to blow. also say a coolant hose ruptures, all the coolant is then drained from the radiator and the engine is then essentially running with no way to cool down, gasket blows. there are many ways for the engine to run hot, but it is the main reason a head gasket would blow out.


Why would there be blow back coming from the radiator?

Cracked head or bad head gasket.


Can driving without oil and water in coolant cause engine to blow up?

no oil in engine or water in radiator will cause engine to seriously o/heat! and eventually seize! major engine damage!!


Why would the bottom radiator hos blow off the engine?

Probably an old hose that should have been replaced. Replace the hose, clamps and the radiator cap. Inspect the other hoses. The radiator cap should release pressure in excess of psi noted on cap, usually 15 to 17 psi.
