The Mazda CX-7 Oil Pump is the heartbeat of the engine that forces only the right amount of lubricant into all moving surfaces to ensure that heat and friction do not win the battle. The gear set on its crank gives it about ten pounds of pressure per thousand revolutions, and thus the amount of oil flowing increases automatically as you step on the accelerator, and it is an easy yet brilliant formula for giving it durability and spirited performance. The fact that all CX-7 versions have a similar architecture under the sheet metal, from the 2.3-liter turbo to the 2.5-liter gasoline and 2.2-liter diesel versions, leads to the pump being able to fit without much ado and maintain each powerplant equally well defended. Mazda has decided to use a low mounting point in the crankcase where a screened pickup feeds the Oil Pump, which enables the Oil Pump to use cooler oil and shorten priming time during cold start, hence resulting in easier mornings and longer bearing life. An inbuilt pressure relief valve will open whenever the readings increase beyond acceptable limits to avoid damaging the seals and still allow the horsepower to be useful, a compromise which allows the Mazda CX-7 crossover to achieve real-world efficiency benefits. Another advantage that drivers enjoy is an immediate warning light which is connected to the pump pressure circuit to provide valuable seconds before damage is done, shutting down a silent protector of wallet and safety. Owners who are performance-minded like that an Oil Pump with high volume can be fitted without altering the factory housing, and it can support high levels of boost and maintain factory tolerances. Rough-cast aluminum construction, short gear clearance, and a direct mechanical connection that does not rely on wimpy belts are some of the reasons why Mazda cars gain a reputation for going the distance with minimal effort.
