Kia People mover Range

The four-cylinder engine in your car is fitted with a timing chain which should be good for the life of the engine. Other Kia engines including the V6 used a rubber timing belt which requires periodical replacement. However, it’s not that simple and some owners have found that even engines with timing chains need these replaced long before the engine has worn out.

It’s sometimes a case of flawed design or poor quality parts that causes this, but in the majority of cases, timing chain failure is caused by a lack of proper maintenance on the part of the car’s owner.

Oil manufacturers recommend a 5W20 or 5W30 fully synthetic oil for this vehicle. For the record, you’ll need 4,5 litres to perform an oil change, and don’t forget to replace the oil filter at the same time. Putting clean oil through an old, dirty filter makes no sense.

While not a common problem, this could be caused by a faulty oil pressure sensor. But it’s important to have this checked out by a mechanic because you could be dealing with an engine that really is suffering from low oil pressure. If the latter is the case, you risk doing permanent and catastrophic damage to the engine because the oil pressure is insufficient to fully protect the internal parts of the engine.

The reason you’re seeing the light come on when the engine is idling (and presumably at operating temperature) is because this is when the engine’s oil pressure is at its lowest. When you rev the engine, the oil pump turns faster, creating more oil pressure. When the engine speed drops again, the pump slows, the oil pressure falls and the warning light switches on.

By having the actual oil pressure checked at a workshop with an independent gauge (separate to the one in the car) you’ll know if the light is coming on because of a duff sensor or because the oil pressure really is too low.
