Mazda Repair: need info on raditor and water pump, head gasket, raditor

Question
i have a 93- 929 mazda in march of 2006 i got my timeing belt done and also my water pump changed.
on 8-25 06 my car started to run hot it looked like a holes had busted because it was smoking after opening the hood all the smoke was coming from my raditor cap like a whole lot of pressure was built up there. so i let it cool off and went back out to ckeck it and i had raditor fluid all over the ground. So i filled it back up it see were it was leaking from and nothing came out. I let it run for a while after about 10 minutes it did the same thing were all the fluid was coming out of my raditor cap. so this time i replaced the whole raditor and the cap and  filled it up ran it again and it did the same thing. the person who but it on said he think my water pump is not working so i took it back to him and he told me he said i had a cracked head gasket. I need help my old raditor needed to be changed yes it did but a checked it every other day and if it need a little bit i would top it off. my raditor always had fluid in it if that is the case and my car started running hot. this is what i need to no if your raditor has water in it and your car runhot was it my raditor or my water pump that made it run hot and cracked in head gasket. thanks ronald  

Answer
A failed head gasket "which does not necessarily need any reason to fail" probably caused the entire scene to unfold. A failed water pump will leak visibly when it dies. It will also make noise, grinding and squealing as it eats itself to death. The coolant, if not changed every 2 years or so, can eat away at the head gasket and cause premature failure. The issue is not how much water is in your radiator, but the radiators ability to hold pressure. Pressure prevents the coolant from boiling and thus turning into steam. The coolant needs to be in liquid form to offer maximum cooling. I believe that the old coolant took both the radiator and the head gasket. I recommend that you have the whole systems chemically flushed and then filled with Peak Global Antifreeze at a ratio of 50/50 and keep a flush and fill schedule of every 2 years. I use the inspection sticker as my calendar and replace it every other inspection for all of my cars.
Sorry to hear of you misfortune, I hope the car is acting better now and wish you good luck and happy motoring for the future.
