VW Engine Oil Pump - Hepu 03H115105L

Product Information

An engine oil pump is a critical component of a vehicle’s lubrication system. Its main job is to circulate engine oil under pressure to moving parts such as the crankshaft, bearings, camshaft, and valve train. This reduces friction, cools components, and ensures proper engine performance and longevity.

Key functions:

• Lubrication – delivers oil to reduce wear on moving parts.
• Cooling – helps carry away excess heat from engine components.
• Hydraulic support – powers systems like hydraulic lifters and variable valve timing.

• Low oil pressure warning light – illuminated on the dashboard due to insufficient oil flow.
• Engine overheating – oil circulation failure increases friction and heat.
• Unusual engine noises – knocking, ticking, or grinding sounds from unlubricated parts.

Other Possible Signs

• Frequent or severe engine wear (scored bearings, worn camshaft).
• Oil pressure gauge reading abnormally low or fluctuating.
• Metal shavings in oil (from insufficient lubrication).
• Complete engine failure if the pump seizes or oil starvation occurs.
