VG1500070051 HOWO Oil Filter Seat

The VG1500070051 HOWO Oil Filter Seat is a key mounting and sealing part for HOWO heavy-duty trucks' engine lubrication systems (tractor, cargo, dump trucks). It acts as the fixed base for the oil filter, connecting the filter to the engine block and sealing the oil circuit tightly. This stops engine oil leakage, keeps the lubrication system's oil pressure stable, and ensures continuous oil supply to engine parts like crankshafts, connecting rods, and camshafts-super important for reducing engine wear and making the engine last longer.

We use good materials and precise machining to make it: the seat body is high-strength ZL108 aluminum alloy, with good thermal conductivity and anti-corrosive. The sealing surface is precision-ground, so the flatness error is no more than 0.03mm. The internal oil passage is optimized for smooth oil flow. The mounting holes, bolt specs, and oil circuit interface fit the original HOWO engines (WD615, WD12) exactly, so it installs with no mods. It handles tough conditions-150℃ engine heat, 5-550Hz vibration, and road dust/water-without the seat cracking, sealing surface damage, or oil passage blockage. Swapping it is easy: no need to modify the engine or oil circuit, just take off the old seat's bolts, clean the mounting surface, install the new seat, and tighten the bolts to 30-35N·m in a crisscross order. Before shipping, we test 'em strict: check sealing (no leaks at 0.5MPa), flatness, and torque resistance-so it's reliable.

Great sealing: Precision-ground surface + optimized structure form a tight seal with the filter, no oil leaks even after long engine vibration. Leakage rate 98% lower than that of ordinary seats.

Stable structure: ZL108 aluminum alloy seat is stiff and load-bearing, firmly fixing the filter without loosening, and won't deform from vibration or temperature changes.

Perfect for HOWO: Made to HOWO's original engine design-mounting hole spacing, oil circuit interface, bolt hole size match. No adapters or new bolts needed-saves 35% maintenance time vs universal seats.

Durable & reliable: Anti-corrosive aluminum alloy resists rust and oil erosion, precision oil passage ensures smooth flow. Works stably in extreme temps and harsh environments-lasts 300k+ km.

This Oil Filter Seat (Model: VG1500070051) is only for HOWO heavy-duty trucks-A7, T7H, T5G models with WD615/WD12/WP10 engines. It won't work on other HOWO engines (like WP12) or other brands (FAW Jiefang, Dongfeng Tianlong). Those have different engine block structures, oil circuit interfaces, or mounting holes-this seat won't fit or work.

Working conditions: -30℃~150℃; ≤0.5MPa sealing pressure; ≤0.03mm flatness; ≥300,000 km life

Q1: Works on HOWO trucks with WP12 engines?

A1: No-WP12 has a different engine block structure and oil circuit interface. It causes mismatched holes or poor sealing, leading to leaks or filter installation failure. Get the oil filter seat for WP12 engines instead.

Q2: Engine oil leaking after new seat install?

A2: First, clean the sealing surface (no oil/debris/scratches). If clean, check filter installation (no loose/misalignment). If the filter is good, tighten the bolts crisscross to 30-35N·m. Still leaking? Replace the seat (rare defect).

Q3: How to maintain the oil filter seat?

A3: 1. Check bolts for looseness every 15k km (tighten crisscross); 2. Clean the sealing surface and oil circuit often to remove sludge; 3. Inspect the sealing surface for scratches during filter replacement-replace the seat if damaged.

Q4: Need to replace the oil filter with a new seat?

A4: Recommended but not mandatory. New seat works best with a new filter-old filters affect sealing and lubrication. Replace both for better engine protection.
