Mazda RX-7 Water Pump
The Mazda RX-7 Water Pump prevents the rotary engine from cooking itself by constantly pumping coolant through the block and radiator. It serves the primary purpose of pumping the coolant through the radiator to the water jacket of the cylinder block and then allowing the liquid to absorb the combustion heat and then giving it back through the radiator fins. Older Mazda models use a belt off the crankshaft pulley to rotate the pump shaft, although some of the newer models might use electric drive to accomplish the same flow but adjust the flow direction as the coolant flows. The housing has an impeller attached to the shaft that forces the coolant forward and a tight seal that prevents fluid access to the bearings, therefore making them last. Older units applied heavy cast iron, but almost all present-day castings are lightweight aluminum, which reduces the mass and is resistant to corrosion. The pump is attached at the bottom radiator hose, forcing coolant into the engine passages, through the thermostat, and through the radiator loop back. When the impeller breaks, the seal is leaking, or bearings screech, the overheating temperature and leaks give a Mazda driver little time to notice before severe overheating hits. In the second generation RX-7 the belt-driven design was maintained, but subsequent rotary versions allowed an electrically driven Water Pump, the highly significant modification since an electric motor ensures that the coolant circulates even when the engine speed drops to idle. In general, the Mazda cooling system is not complicated, but the basic principle of the system is constant coolant flow that ensures safety of the high-speed rotary core, and the Water Pump is the core of the circulation.

Mazda RX-7 Water Pump Parts and Q&A
- Q: What are the steps involved in removing and replacing a water pump on Mazda RX-7?A:The water pump is at the front of the engine, and is driven by a belt on the fan pulley, the problems that it may have are, bearing failure, or water gland leakage, the latter may be seen by the engine leaking behind the pulley via a hole known as a weep hole. Failure in bearing can create a squealing sound or overly free movement, which can be examined with the help of a length of hose listening to sounds being careful with moving engine parts. This water pump can be taken out easily without having to unscrew the significant engine components, even when it is not easily accessible. First of all, secure the front fenders and disconnect the negative battery wire. In case there is air conditioning available, unscrew the bolts of adjusting compressor and detach the Drive Belt. Likewise, take off pressure on air pump and alternator drive belts. Drain the coolant: this is done by removing the lower radiator hose and removing the fan assembly and adjustment brackets to the alternator and the air pump. Install Air-conditioning pulley Detach air conditioning pulley, if present. Then the water pump is taken out by unscrewing the securing nuts and bolts and then the fan flange and the pulley are removed off the pump. Wipe the surfaces of the gasket, fit the fan flange and pulley to the new water pump and wipe silicone sealer round the gasket surface before fitting the pump and attaching it by using nuts and bolts. Install the alternator adjustment bracket and screw the water pump attaching bolts up to the required torque. Install the alternator drive belt again, and set the alternator drive belt correctly in tension, and proceed with the air pump and air conditioning system as needed. Lastly, screw on the fan assembly, clamp the lower radiator hose, pour some coolant mixture into the radiator, reconnect the battery cable, and turn on the engine to test whether there are any leakages.
