A sump pump is located beneath the engine block, and is designed to gather oil that has been pumped around the engine. The sump plug is located at the base of the pump and allows the oil to drain away when the plug is unscrewed. There are two types of sump, a dry sump and a wet sump - with the latter featuring on almost all road cars. If you’re a fan of motor racing, you might have heard of a dry sump, which is a component found on professional racing cars that collects the oil and redistributes it via a pump - leaving the sump dry.
The sump pump and sump plug are two e engine parts that should be checked for faults on a regular basis. As mentioned, they hang down beneath the engine and are prone to damage caused by debris and speed bumps. To maintain an exceptional engine performance, a faulty sump should be replaced as soon as you detect a fault. Replacing a sump plug is fairly inexpensive and can be done during an oil change.

Sump Plug and Pumps FAQs
What is a sump plug?
It’s a small bolt fitted at the bottom of the sump pan. You remove it when draining engine oil during a service, and replace it to seal the oil back in.
Are all sump plugs the same size?
No, they vary depending on the make and model of the car. Using the wrong size can lead to leaks. It’s always best to check the exact fit for your vehicle.
Are sump plugs universal?
Not really. Some aftermarket options claim to be universal, but for a proper seal you need one made to fit your car. Halfords can help you find the right plug by registration.
What is a sump pan?
It’s the metal pan fixed to the bottom of the engine that holds the engine oil. The sump pan also has the sump plug fitted so you can drain the oil when needed.
