Replacing for normal cooling .. this is the 17" version for capacities described as "normal use" ... so in reality it should be ok for hot Australian / NZ summers etc... if you have the fan shrould opening to accept it ongoing.

Your factory should for this needs to be 19" at least.. allowing you to check engine tilt on reving.. you now.. put the boot in and the engine will tilt a bit. If the engine mounts are crook.. it may cause the blade to coming into contact with the shroud and result in damage.. so check this.

This does not bolt up to thermo fans.

This has the small locator hole hub.
