Now then.. I've had a similar problem with my Scania wagon, no fire but water pump problems. You may have no coolant in the pump, Scania has to be filled with coolant from the bottom hose to purge air, Peugeot cars are notorious for airlocks & have bleeders on. One would just imagine you tip the coolant in & done,, but just check for air eh.. All engines should have coolant made from water/antifreeze mixed at 33 0r 50%, never plain old water
