Oil Pump

what’s an oil pump and what’s its job in a car?

There are a ton of parts in a car that help it start up and get moving. Car parts like the oil pump, fuel pump, spark plugs and spark plug wires, battery, alternator, and so on, all gotta work well to ensure the safety of the driver and passengers and also to get the car moving.

The engine or powertrain is one of the most complex parts of any car, and car manufacturers usually put in a lot of effort to improve its performance and efficiency. The parts in a car’s engine operate under high pressure and temperature, and they move at a very high speed.

When the piston moves inside the cylinder, there’s a lot of friction between these metal parts, which can wear them down over time. This friction also generates heat, and one of the main jobs of engine oil is to cool these parts down.

Car engineers use special oils to prevent an increase in temperature and also to prevent engine parts from wearing out. These oils don’t lose their lubricating properties at high temperatures. But to circulate the engine oil in the powertrain, you need a part called an oil pump or oil pump.

The oil that’s in the oil pan is pressurized by a pump and reaches the engine parts, preventing severe friction between these parts and, as a result, preventing an increase in their temperature. This pump, which has a practical role in the vehicle and gets its driving force from the crankshaft, is called an oil pump.

The proper operation of the oil pump in the car increases the lifespan of the engine and the parts in it, and if you neglect the potential defects of this vital part, it will cause a lot of damage to your vehicle.

The oil pump sends the oil to the oil filter, and after the oil flow passes through the filter, this fluid is sent into the engine’s oil circuit. Oil plays a very important and vital role in the car, and any defect or failure of it will lead to serious damage to the car.

The movement of the oil pump is provided by the camshaft or crankshaft. In camshaft engines, there’s a gear on the camshaft that moves the oil pump shaft, and this shaft movement also moves the distributor. In such cases, when opening and closing the oil pump, you should pay attention to the position of the distributor hammer and the position of the pistons.

Types of Oil Pumps

Oil pumps are divided into three main categories. Gear pumps work by rotating two gears of the same size. In these pumps, oil enters the pump and is sent out by being placed between the gears and the pump body.

The second type, rotary pumps, are similar in operation to gear pumps, with the only difference being that they use a gear that rotates inside an internal rotor.

The third type is needle oil pumps, where the oil in them is sent out by a plunger and spring; however, these types of pumps are mostly used in motorcycles.

The oil pump, by providing its oil, lubricates the engine while it is working. This lubrication prevents the metal parts of the engine from contacting each other. The oil pump, while working, also absorbs the heat of the engine parts.

Signs of a busted oil pump

There are a bunch of signs that could mean your oil pump is toast. Some common ones include: noisy car valves, drop in oil pressure, increase in engine temperature, and noise coming from the oil pump itself.

Drop in oil pressure or check engine light coming on

The oil pressure is regulated by the oil pump. When the oil pump goes bad, the oil pressure in the engine starts to drop. Usually, when the low oil pressure warning light comes on, it’s the first sign of low oil pressure on your dashboard.

When this happens, check your oil level. If it’s really low, add more oil until the oil level is back to normal. If your oil pressure is still low after doing this, it means your oil pump is busted. Before the symptoms get worse, replace the pump quickly.

Increase in engine temperature

When oil enters the engine, it acts as a lubricant and also cools the moving metal parts of the engine. When the engine doesn’t get enough oil, these metal parts come into too much contact and generate heat, which will increase the engine temperature of the car.

When the engine gets too hot, it can damage the engine and its parts. Since repairing this kind of damage is pretty expensive, it’s better to immediately visit one of the authorized Renault dealerships across the country when your car’s warning light comes on.

Noisy valves There are important parts in the valve system that enable the engine to continue working. All these parts depend on the flow of oil through the oil pump to be lubricated. When they are not lubricated due to low oil, the operation of these parts is disrupted and stopped. With a decrease in oil level, the valves also make a lot of noise.

Noise from the oil pump A noisy oil pump is a rare sign, because oil pumps only make noise when they start to go bad. Probably when this happens, you’ll hear a lot of noise, even when the car is idling. This indicates that the internal gears of the pump are worn out, so you need to replace the entire pump.
