Fan clutches obviously never literally explode. The fan does not come apart from its assembly spontaneously due to clutch failure. That is now clearly seen to be a misdiagnosis. The engine's mountings fail, causing the engine itself to judder especially when the car is driven over bumps etc. The fan's blades hit the shroud or something else, and the impact coupled with its fast spinning momentum causes it to become dislodged and unleash itself upon the car and its bonnet, and ultimately upon the owner's wallet.
