Where is the Drain Valve Located on a Weichai Engine?

[McHailey]

The drain valve on a Weichai engine is typically located below the intake manifold, adjacent to the oil cooler. Features of Weichai engines: 1. Base-mounted structure, greatly facilitating maintenance and reducing workload; 2. Crankshaft made of high-strength ductile iron with nitriding treatment; 3. Wet cylinder liners use boron alloy cast iron, with inner surfaces honed with a plateau crosshatch pattern for high strength, low wear, and long service life; 4. Pistons equipped with three compression rings and one oil ring, the first being a chrome-plated barrel-faced ring for excellent break-in characteristics; 5. Available with either pneumatic or electric starting systems; 6. Speed control system offers either mechanical or intelligent electronic governing options.
