The 202V018106010 Cylinder Head Oil Filler Cap is a small but essential engine component that seals the oil fill opening on the cylinder head of SINOTRUK Sitrak heavy‑duty trucks. This cap prevents oil from splashing out during engine operation, keeps contaminants from entering the oil system, and maintains proper crankcase pressure. Its easy‑grip design and secure bayonet‑type locking mechanism allow for quick and convenient oil top‑ups without tools, making routine maintenance faster and cleaner.
Manufactured from high‑grade engineering plastic reinforced with glass fiber, the 202V018106010 cap offers excellent dimensional stability, heat resistance, and mechanical strength. The integrated rubber O‑ring provides a positive seal that resists oil leakage and prevents the cap from loosening due to vibration. This genuine OEM component is a direct replacement for the original factory cap, ensuring a perfect fit and restoring the sealing integrity of the cylinder head oil fill port.
Using the correct oil filler cap is vital for engine health; a loose or worn cap can cause oil mist to escape, leading to a dirty engine bay, oil loss, and potential fire hazards. The 202V018106010 cap eliminates these risks, providing reliable sealing, easy access, and long‑term durability for your Sitrak truck’s engine.
The 202V018106010 cap features a precision‑molded rubber O‑ring that creates a tight seal against the cylinder head, preventing oil leaks and keeping dirt and moisture out of the engine oil system.
Constructed from glass‑reinforced polyamide (PA66+GF), the 202V018106010 cap withstands under‑hood temperatures up to 150°C, ensuring reliable performance in hot engine environments without warping or degrading.
The cap’s large, knurled grip allows for easy hand‑tightening and removal, making oil level checks and top‑ups quick and convenient, even with gloves on.
Designed for heavy‑duty use, the 202V018106010 cap resists cracking, fading, and oil degradation, providing dependable service for over 100,000 kilometers under normal operating conditions.
Prevents Oil Leaks: The 202V018106010 cap ensures a tight seal, eliminating oil seepage that can dirty the engine, cause oil loss, and create fire hazards.
Keeps Contaminants Out: A properly sealed filler port prevents dust, dirt, and moisture from entering the engine oil, protecting internal components from abrasive wear and corrosion.
Maintains Crankcase Pressure: The cap helps maintain the correct pressure balance in the crankcase, reducing oil mist emissions and supporting optimal engine breathing.
Easy & Convenient: The tool‑free design allows for rapid oil checks and refills, saving time during routine maintenance and reducing the risk of cross‑threading.
Cost‑Effective Maintenance: Replacing a worn or damaged cap with the 202V018106010 is a low‑cost preventive measure that avoids expensive engine repairs caused by oil contamination or loss.
OEM Interchangeability: The 202V018106010 cap is a direct cross‑reference for multiple OEM part numbers, ensuring broad applicability across the SINOTRUK truck range.
Compatible Models:
The 202V018106010 cap is compatible with the standard cylinder head oil fill port used across the SINOTRUK heavy truck range. Always verify the thread size (M32 × 1.5) and O‑ring condition before installation.
Installation Tips & Best Practices:
The 202V018106010 oil filler cap is produced using precision injection molding techniques that ensure consistent dimensions and high surface quality. The glass‑fiber‑reinforced polyamide (PA66+GF) material offers an excellent balance of strength, heat resistance, and dimensional stability, even at elevated temperatures. The integrated O‑ring is made from a specially formulated nitrile rubber that resists engine oil, heat, and aging, ensuring a long‑lasting seal.
Each 202V018106010 cap undergoes strict quality inspections, including dimensional checks, O‑ring hardness and compression set tests, and visual inspections for surface defects. The cap is also tested for resistance to oil immersion and thermal cycling to guarantee reliable performance in the harsh under‑hood environment of heavy‑duty trucks.
The cap’s knurled outer surface is designed for a secure grip, even with oily hands, and the bayonet‑style thread ensures quick and positive engagement. Every cap is marked with the OEM part number for easy identification and traceability, ensuring you receive a genuine, high‑quality component that meets SINOTRUK’s rigorous standards.
