Product Introduction 3408510LE010 Power Steering Reservoir serves as the storage tank for hydraulic steering fluid on HFCN721 light truck steering assembly. It stores steering oil, stabilizes system pressure and allows air bubbles to separate out from circulating fluid during operation. This aftermarket replacement tank fixes persistent fluid leakage, fluid contamination and air entrapment issues caused by cracked housing, loose connector ports and broken built-in filter screen of original reservoirs, preventing stiff steering and abnormal pump noise for urban distribution and short-haul cargo delivery vehicles.
Product Advantages High-strength plastic housing resists heat and vibration inside the engine compartment. Integrated mounting lugs align perfectly with factory bracket for straightforward fitment. Built-in filter screen intercepts coarse impurities before oil flows to steering pump. Each reservoir undergoes pressure leak testing before shipment, equipped with standard ports to match original steering pipelines.

FAQ
Q1: What causes foam to build up inside the steering reservoir?
A1: Air sucked in through loose joints or low fluid level creates foam and disrupts hydraulic assist.
Q2: Can I weld small cracks on the plastic reservoir instead of replacing?
A2: Plastic welding is not reliable under oil pressure; replacement is the safer solution.
Q3: What level should steering fluid be kept at inside this tank?
A3: Maintain liquid level between MIN and MAX marks, check level when the engine is cold.
