Mitsubishi Oil Pumps FAQ

What Does an Oil Pump Do for a Mitsubishi?

Put simply, it works with the crankshaft to circulate motor oil throughout the engine. In doing so, the oil can lubricate engine parts, helping them work their best, and helping the engine run as well as it can, for as long as it can.

The process works like this. First, the pump's impeller creates a vacuum, pulling oil into the pump. Then, a drive gear pressurizes the oil, sending it throughout the engine afterward. Meanwhile, a relief valve regulates oil pressure, keeping it from getting too high and thereby helping prevent engine damage.

What are the Symptoms of a Failing Mitsubishi Oil Pump?

For one, knocking; this tells you that metal parts in the pump are probably rubbing together. Secondly, a burning smell; this is most likely because of a leak, and that, because of a faulty seal. Third, the needle on the oil pressure gauge dropping, indicating low oil pressure. Others include engine underperformance, loss of power, trouble speeding up, overheating, and engine failure.

These signs tell you that it's time to run an engine inspection and replace the oil pump if the results call for it; after all, letting a bad oil pump go long enough can mean catastrophic engine damage and one serious bill for repairs.

How Much Does Mitsubishi Oil Pump Replacement Cost on Average?

According to recent RepairPal data, anywhere from $1,240 or so to $1,450 or more. Cost can vary by model, however; Mitsubishi Outlander oil pump replacement, for example, can run $1,780 to $1,950 plus.
