Haval F7 1.5 Turbo (GW4B15A, 150 hp) (2025): Engine Oil and Oil Filter Replacement

Oil changes on the 1.5 Turbo GW4B15A are done every 10,000 km or once a year. The engine requires full synthetic oil meeting API SN, in 0W-30 or 5W-30 viscosity. The lubrication system capacity is 4.8 L (5.1 qt). The procedure is standard and can be done in a home garage.

Difficulty: Easy Time: 30-40 minutes Steps: 9 Tools: 17 mm wrench (drain plug), oil filter wrench, funnel, drain pan for 5-6 L (5.3-6.3 qt) of used oil, shop rags

Part

  • 🔩 Engine oil 5W-30 or 0W-30 API SN (full synthetic), 4.8 L (5.1 qt). Oil filter 1017100XEB02, drain plug gasket 1009305XEC06

Step by step

9 steps
  1. Warm the engine up to operating temperature (80-90°C), shut it off, and let it cool for 5 minutes.
  2. Raise the front of the vehicle on a lift or set it on secure jack stands. Remove the engine skid plate (6 bolts, 6 plastic clips).
  3. Place the drain pan under the drain hole in the oil pan. Remove the drain plug with a 17 mm wrench (counterclockwise). Let the oil drain completely (5-7 minutes).
  4. Replace the copper drain plug gasket with a new one (1009305XEC06). Install the plug and tighten to 25-35 N·m (18-26 lb-ft) (if you don't have a torque wrench, hand-tight plus a quarter turn with the wrench).
  5. Move the pan under the oil filter (located on the right side of the engine, with limited access). Loosen the filter with a claw-type or chain filter wrench, then unscrew it by hand. Wipe the mounting surface on the block.
  6. Lubricate the rubber gasket of the new filter with clean oil. Screw the new filter on by hand until the gasket touches the block, then tighten an additional three-quarters of a turn (do not use a tool to tighten it).
  7. Pour 4.5 L (4.8 qt) of oil through the oil filler neck. Close the cap, start the engine for 30-60 seconds, and let the oil pressure light go out.
  8. Shut off the engine and wait 3-5 minutes. Check the level with the dipstick; the mark should be between MIN and MAX. Top up if needed to the middle of the range (usually an additional 200-300 mL (7-10 fl oz)).
  9. Inspect the drain plug and filter for leaks. Reinstall the skid plate.

Common mistakes and warnings

  • Do not mix oils of different brands or viscosities unless absolutely necessary. Use only synthetic oils rated API SN or higher, because a turbocharged engine is very sensitive to oil quality. Replace the drain plug gasket at every oil change, since reusing it leads to leaks.
