Question about 2001 Mazda Protege
The heater fan inside works fine but there is simply not enough heat blowing out. Air works fine. Engine squeals when fan is on. ad fan belt replaced but engine still squeals?
Sounds like water pump falining to me ..also check thermostat and replace with water pump if old or not opening.(remove thermostat and test in hot water)

Possible that the fan belt is not tensioned right or that the water pump is binding causing low flow through the heater.
If belt is not loose, release it more and try turning the water pump by hand to see if it is binding.

Just took my car to the shop for the same appearent reason me also thinking it may be lifters. My mechanic said it spounds like a worn wrist pin ...... bad news for you if this is the case .......recomendations rebuild the engine or buy a new or remanufactured one. if the wrist pin lets go then you could throw a rod. If you must drive the car please be gentle

did you check the fluid level by removing the rad. cap? Radiator should be full to top. If Chryslers are low on coolant, the heater will not blow warm air.

SOURCE: OVER HEATING
In the fan circuit...You have a temp switch screwed on the radiator, a fuze and a relay in the fuze box plus a fan. Swap the relay with another relay, replace the fuze. The other fan should come on when the a/c is turned on. If you fix the fans and it still overheats, you may have a BLOWN HEAD GASKET. ALSO ARE YOU BLEEDING THE AIR FROM THE SYSTEM? DO YOU SMELL EXHAUST IN THE COOLANT?

my 2001 mazda protege starts hard, idles low and high at various times (never normal) and it acts as though its going to stall at all times. sparks and wires are changed no help, changed air filter no help. any idea on what to do?

the problem is probably the heater core, it can become clogged with dribris. this stops heat from the engine getting to it and then no heat.
