VG2600010489 Oil Filler Cap

The VG2600010489 oil filler cap is a key sealing and protective component for the engine oil tanks of HOWO heavy-duty trucks (tractors, cargo trucks, and dump trucks). It tightly seals the oil filler port, preventing engine oil leakage during vehicle operation and keeping dust, water, and debris out of the oil tank. This keeps the engine oil clean, avoids abnormal wear of internal engine parts (crankshafts, bearings, pistons) caused by impurities, and maintains stable engine lubrication - critical for extending engine life.

Our caps are manufactured with high-quality materials and precision workmanship. The cap body is made of high-strength PA66+glass fiber engineering plastic, which is stiff and heat-resistant. The internal sealing ring is made of nitrile rubber, offering oil resistance, high-temperature resistance, and good elasticity. The threaded structure is precision-tapped to match the oil filler port threads perfectly with no slippage. Overall dimensions, thread specifications, and sealing design are fully compatible with original HOWO engine oil tanks (WP10, WP12, WD615), allowing for direct, modification-free installation.

It performs reliably under harsh conditions: withstanding 150℃ engine compartment heat, 3–500 Hz road vibration, and engine oil exposure without cap deformation, seal aging, or thread wear. Replacement is simple: no professional tools are required. Simply unscrew the old cap counterclockwise, clean the filler port surface, and screw the new cap clockwise until tight.

Before shipment, all caps undergo strict testing: sealing performance (no leakage at 0.3 MPa), heat resistance (stable performance at 150℃ for 2 hours), and torque test (no slippage at 25 N·m), ensuring consistent reliability.

Great sealing: Elastic nitrile rubber seal + precision thread form double sealing, preventing oil leaks and foreign matter. The leakage rate is 99% lower than ordinary caps.

High temp & wear resistant: PA66+glass fiber cap withstands 180℃ without deformation, nitrile rubber seal resists oil and aging-3x longer life than ordinary rubber seals.

Perfect for HOWO: Made to HOWO's original engine oil tank design-thread specs, cap size, and sealing structure match. No modification or adapters needed-saves 30% maintenance time vs universal caps.

Durable & easy to use: High-strength cap is impact-resistant, non-slip surface facilitates unscrewing/tightening. Works stably in complex conditions-lasts 300k+ km.

This Oil Filler Cap (Model: VG2600010489) is only for HOWO heavy-duty trucks-A7, T7H, T5G models with WP10/WP12/WD615 engines. It won't work on other HOWO engines (like WP13) or other brands (FAW Jiefang, Dongfeng Tianlong).

Installation: Direct replacement-fits original engine oil tank thread and size

Working conditions: -30℃~150℃; ≤0.3MPa sealing pressure; ≤25N·m torque resistance; ≥300,000 km life

Q1: Works on HOWO trucks with WP13 engines?

A1: No-WP13 has different oil filler port thread specs and size. It causes loose sealing or inability to install, leading to leaks or foreign matter intrusion. Get the oil filler cap for WP13 engines instead.

Q2: Oil leaking around filler port after new cap install?

A2: First, clean the filler port surface (no oil/debris/scratches). If clean, check the cap's sealing ring (intact and correctly installed). If the seal is good, tighten the cap sufficiently. Still leaking? Replace the cap (rare thread defect).

Q3: How to maintain the oil filler cap?

A3: 1. Clean seal and internal thread every 10k km (remove sludge/debris); 2. Inspect seal for aging during oil replacement (replace cap if seal is damaged); 3. Avoid over-tightening to prevent thread deformation or seal damage.

Q4: Compatible with synthetic/semi-synthetic oil?

A4: Yes, compatible with all HOWO engine-specified oils (synthetic, semi-synthetic, mineral). Nitrile rubber seal is oil-resistant-adapts to different oil types without affecting sealing.
