Dayco Engine Water Pump P/N:DP959
Dayco DP1279 water pump for the 1979-1985 Mazda RX-7 circulates coolant through the engine and radiator to carry heat away. It replaces a worn or leaking pump and is also listed as an engine water pump.
Coolant seeping from the pump, a grinding or whining noise from the pump area or an engine that runs hot can all be signs of a worn pump. These signs alone do not prove the pump is the problem, because a stuck thermostat can also cause overheating. If the pump is the cause, this one replaces it.
This pump fits the 1979-1983 Mazda RX-7, the 1984-1985 RX-7 1.1L and the 1985 RX-7 1.3L. The 1979-1985 Mazda RX-7 takes one.

How can I tell if an old water pump is wearing out?
With the engine off and cool, look for coolant residue or drips around the pump and check for play in the shaft. A grinding or whining noise from the pump area can also be a sign; a shop can test it.
Is Dayco DP1279 sold as a single water pump?
Yes. This listing is one water pump, and the fitment lists a quantity of one per vehicle.
Can I keep driving with a leaking water pump before replacing it?
No. A leaking or noisy water pump should be checked or replaced promptly, since low coolant can lead to overheating. A shop can inspect it.
