powersteering belt off first, then water pump, each has its own ten.
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.
Drain the water from your Mazda Protege radiator. Remove the hoses from your radiator. Remove the radiator stabilizing arm. Remove the radiator retaining bolts. Reverse the process to install the new radiator.
you do nothing
It is under the timing cover and driven by the timing belt. Anytime you change one it is best to replace both as far as cost is the same.
In Canada, about $500 to replace both. The parts themselves are probably worth $100 but there's a lot of labour involved.
You have either a blown head gasket or a cracked head
Replacing the 1997 Mazda water pump will cost approximately $300. The water pump will cost about $75 and will require four hours of labor.
Check the engine thermostat.
You have to take off the serpentine belts so that you can remove the pulley for the water pump. You also have to take off the cam head so that you can get to the timing belt case and remove the plastic splash guards in front of the water pump. Remove the timing belt, then there are 4 bolts attaching the water pump. Remove those bolts and then disconnect the water intake and put your new pump in and replace the timing belt. **Make sure that your timing marks are located where they need to be before replacing the timing belt.**
The water pump is located behind the timing belt inside the timing belt cover. It is also attached to the water neck for the lower radiator hose. If you've never done a T-Belt seek supervision.
No
The timing belt should be changed every 168,000 kms (105,000 miles) on Mazda Protege 5, not 100,000 kms (60,000 miles). Also these engines DOHC (Dual Overhead Camshaft) is INTERFERENCE motor, which means when that belt skips few teeth or breaks, kiss your valves goodbye. You'll need a new cylinder head, big $$$. Might as well do your water pump at the same time and serpentine belt.
