A car engine oil pump is an essential component of a vehicle’s engine. It ensures that engine oil circulates properly, keeping the engine parts lubricated and cool, preventing damage caused by friction and wear. If you’re unfamiliar with how an oil pump works or when it’s time to replace it, this guide will take you through everything you need to know—from its function and types to common problems and how to replace it.

What is the Function of a Car Engine Oil Pump?

The primary function of a car engine oil pump is to circulate engine oil under pressure throughout the engine. Oil plays a crucial role in lubricating the engine’s moving parts—such as bearings, pistons, and the camshaft. The oil pump ensures that oil is distributed evenly, reducing friction between these parts, keeping the engine cool, and preventing premature wear.

The pump draws oil from the oil pan and sends it through the oil filter, cleaning the oil before it reaches the engine components. This process is vital for the smooth operation of your car, ensuring your engine stays efficient and performs at its best.

For example, if you own a car like the Changan Deepal S07, which is known for its advanced technology, the oil pump becomes even more vital in ensuring optimal engine performance.

Types of Car Engine Oil Pumps

There are four main types of oil pumps used in cars, each offering unique benefits. Understanding the differences between these oil pumps can help you maintain your vehicle’s engine.

1. Gear Oil Pump

The gear oil pump is one of the most commonly used oil pumps in modern engines. It works by using two intermeshing gears to pump oil. This type of pump is known for its reliability and simplicity.

2. Rotor (Gerotor) Oil Pump

A rotor oil pump consists of two rotors—one inside the other. The inner rotor turns within the outer rotor, creating pressure and pushing oil through the engine. These pumps are compact, efficient, and often found in vehicles like the Changan Oshan X7 Comfort.

3. Vane Oil Pump

In a vane oil pump, vanes slide in and out of a rotor, creating a vacuum that draws in oil and pushes it out. This type of pump is less common but can be effective in certain engine designs.

4. Plunger Oil Pump

The plunger oil pump uses a piston-like plunger to pressurize the oil and push it through the system. It is often found in high-performance engines where greater pressure is required for lubrication.

Common Problems with Car Engine Oil Pumps

Just like any other mechanical part, the oil pump can face issues over time. Here are some common problems associated with a car engine oil pump:

1. Low Oil Pressure

One of the most common signs of a failing oil pump is a low oil pressure warning light. This can indicate that the pump is not circulating oil efficiently, which can lead to engine overheating and potential damage.

2. Unusual Noises

If you hear clanking or ticking noises coming from the engine, it might be a sign that the oil pump is not providing enough lubrication to the moving parts. This can lead to increased friction and engine wear.

3. Engine Overheating

An oil pump that is not functioning correctly can result in reduced oil circulation, causing the engine to overheat. This is a serious issue, as excessive heat can cause irreversible damage to the engine.

4. Reduced Engine Performance

A malfunctioning oil pump may lead to a drop in engine performance. This could result in sluggish acceleration, reduced power, and overall engine inefficiency.

If you’re experiencing any of these problems with your vehicle, such as a Changan Deepal S07, it’s essential to address them as soon as possible to prevent costly repairs.

Car Engine Oil Pump Replacement Guide

If your oil pump fails, it’s crucial to replace it immediately to avoid further damage. Here’s a step-by-step guide to the oil pump replacement process:

1. Drain the Engine Oil

Before replacing the oil pump, you’ll need to drain the engine oil. This ensures that no oil is left behind when the pump is removed, and it also prevents contamination.

2. Remove the Oil Pan

The oil pump is typically located near the bottom of the engine. To access it, the oil pan must be removed. This may require detaching other components depending on the engine design.

3. Replace the Oil Pump

Once the oil pan is removed, the faulty oil pump can be replaced with a new, compatible pump. Ensure that the new pump is a high-quality replacement to ensure proper oil circulation.

4. Reassemble and Prime the System

After the new pump is installed, the oil pan and other components need to be reassembled. It’s important to prime the oil pump to ensure proper oil circulation before starting the engine. This involves manually turning the engine to circulate the oil.

How to Test Your Car’s Oil Pump

To ensure your car engine oil pump is functioning properly, you can perform a few simple tests:

1. Check Oil Pressure

Using an oil pressure gauge, you can measure the pressure in the oil system. Low pressure can indicate a problem with the pump.

2. Listen for Unusual Noises

Engine knocking, clanking, or ticking sounds can be a sign that the oil pump isn’t providing enough lubrication. These sounds should be addressed immediately to prevent further damage.

3. Observe Oil Flow During Maintenance

When performing routine maintenance, observe the oil flow to check for any irregularities. Reduced oil flow may signal a problem with the oil pump.

Conclusion

The car engine oil pump is essential for keeping your vehicle’s engine running smoothly. From circulating oil to preventing overheating and reducing wear, a properly functioning oil pump ensures optimal engine performance. Whether you drive a Changan Deepal S07 or any other model, understanding how the oil pump works and how to maintain it can save you from expensive repairs.
