If it is leaking or noisy then it is bad. You should also be able to see the coolant flow with the engine cool and radiator cap off. Give it time to warm up and you will see the movement of coolant if it is working.

Could you tell me how would you replace the oil pump on a Mazda Protege?
Replacing the 1997 Mazda water pump will cost approximately $300. The water pump will cost about $75 and will require four hours of labor.
This year Mazda protege does not have a serpentine belt. It has two belts, one for the alternator/water pump, and the other for the power steering and a/c.
powersteering belt off first, then water pump, each has its own ten.
Check the engine thermostat.
In the gas tank.
The water pump is under the timing belt cover. To access the water pump, you must first remove both belts, the water pump pully, and the timing belt cover.

Check the timing belt Answer - My 99 Protege was leaking out coolant slowly out of the water pump. A seal on it had gone bad and the pump needed to be replaced. Haven't had a leak or an overheat since new pmp was installed.
1993 protege has it in tank uder rear seat. do not need to drop tank.
