I was driving car it showed no signs of overheating. The radiator popped. Towed the car home. Replaced radiator, replaced fans and the power steering hose(when the radiator popped the fan became loose and piece of fan broke off and sliced the hose). The car was already losing compression and now is worse than ever and is now dying. Oh, after everything else engine is making noise. Who can help me?

The piece coming off the fan probably led to this chain of events. That caused your radiator to get damaged , lose fluid and the engine overheated, probably burned some oil. The radiator wouldn't just pop of itself, if it had simply overheated like your antifreeze was too old the cap would just need replaced, not the whole radiator. You may have blown a head gasket? Does it look like oil around the top of the motor? Or pull out a plug and see if it looks OK.Check your oil level, maybe do an oil change and see if it makes a difference

There will be blow by, an oily stain on the underside of the hood over the engine when you raise it. Or you will see oil leaks on the engine or oily marks on the driveway where you park, the head gasket just seals the engine closed from the top like you screw the lid on a jar. If it's blown you just have to put a new gasket on hopefully the engine block isn't damaged from no coolant. I also thought get the water pump checked too because if that fails it would make a lot of noise.

What do you mean when you say the radiator "popped?" Did the plastic break open or did the metal core itself start to leak? What type of vehicle is this?
