How Often Should the Oil Pump Be Replaced?
2 Answers
Car oil pumps should be replaced every 40,000 kilometers. The oil pump is an important component of the electronic gasoline injection system in a car engine. Below is an introduction to the oil pump: Function of the oil pump: It provides hydraulic pressure for operating control valves and clutches, supplies a measured amount of gear oil to the transmission and differential case, and delivers transmission oil to the cooler for circulation and heat dissipation. Maintenance methods for the oil pump: Avoid using water-containing substances to create a vacuum. After removing most of the solvent in an oven, use the oil pump to create a vacuum. Follow the correct sequence when using the vacuum pump, add the specified grade of lubricating oil, and ensure the fuel is clean, free of impurities and moisture.
The fuel pump generally doesn't require regular replacement and only needs to be changed when it fails. My car has been running for over ten years without ever replacing the fuel pump, until one time it couldn't start when cold and made a buzzing noise. After towing it for inspection, we found out the pump had burned out. The mechanic said fuel pumps typically last 10-15 years or about a hundred thousand miles. He advised paying attention to warning signs like delayed starts, poor acceleration, or stalling. Don't make my mistake of ignoring these symptoms and suffering unnecessary trouble - especially dangerous if the pump fails during highway driving when you might get stranded. He recommended listening for unusual engine sounds and avoiding driving with an empty tank (keep at least 1/4 full to prevent overheating). Under normal driving conditions, there's no need for proactive fuel pump replacement. For older vehicles, regular maintenance checks are always wise - it saves hassle and gives peace of mind.
