Oil Pump Upgrade 2.2 and 3.2 Ranger/BT-50

Gear Drive Pump

Upgraded gear drive oil pump to suit Ford Ranger and Mazda BT-50 2.2 (P4At) and 3.2 (P5At)

Suits all 2011 models

With the new generation 4 & 5 cylinder diesels Ford introduced the variable pressure oil pump, which goes away from the traditional gear drive pumps we all know, and instead utilises a vane style pump allowing the oil pressure to vary according to engine RPM.

The variable pressure pump is a good idea in theory and helps improve engine efficiency, but there are two main drawbacks of this particular pump.   

Firstly you have the 10-minute oil drain time limit, which is not a great hassle if you are aware of it, but to the unsuspecting home mechanic, it can be a very expensive trap. 

Second issue is the pumps are failing prematurely, and oil pressure is lost to the entire engine, causing major engine damage.

From our experience, the failure can happen at any time and without warning, and if the driver doesn’t notice the engine light or oil pressure light within about 30 seconds, it means a trip to the engine builders for repairs. 

Southside Cylinder Heads can supply and fit the pumps for you.

Thankfully a revised oil pump has been released, which converts the variable pressure back to the good old gear drive pump. 

The new design is much more robust and does away with the pesky 10-minute race the clock oil changes. 

All Ford Ranger and Mazda BT50 3.2 engines built by Southside Cylinder Heads incorporates the new pump design.
