Product Intro:
Chery A5 Steering Oil Pump (Part No.: A21-3407010HA)
1. What this part is for & why it matters
This steering oil pump is made just for Chery A5’s power steering system—no other car models fit it. Its main job? Turn mechanical energy into hydraulic pressure, so when you steer the Chery A5, it feels smooth and steady, not heavy. And let’s be real, if this pump acts up, your driving comfort and safety take a hit. The good news? This A21-3407010HA follows OE (original equipment) standards, so whether you’re replacing an old pump or doing maintenance, it’s a solid pick that matches the Chery A5’s original specs.
2. Key details you might care about
First, the part number is A21-3407010HA—make sure you note that if you’re ordering, so you don’t get the wrong one. Itworks for all Chery A5 models, no matter the configuration. The pump itself is a hydraulic power steering type, built with good stuff: the outer shell is high-quality aluminum alloy, and the internal gears and bearings are high-strength alloy steel. It’s not heavy either—only about 1.8 to 2.0 kg, so it won’t add extra load to your car.
When it comes to performance, A21-3407010HA runs at a working pressure between 9-13 MPa, which is exactly what the Chery A5’s steering system needs. The oil flow rate is 2.8-3.2 L per minute too, so there’s always enough hydraulic oil to keep steering smooth. And installing it? Super easy—just bolt it on directly, since it lines up with the Chery A5’s original mounting holes. No drilling or modifying needed.
3. Why this A21-3407010HA is a good buy
First off, it fits the Chery A5 perfectly. It’s designed using the car’s original data, so every size and connection matches the original part—no more oil leaks or weird noises that come from ill-fitting pumps.
Durability is another win. The aluminum shell has an electrophoretic coating, so it resists moisture, dust, and rust—even in the messy engine compartment. The internal gears and bearings? They’re made of tough alloy steel, polished precisely and heat-treated, so their surface hardness is HRC 58-62. With normal use, this A21-3407010HA can last over 60,000 km—way more reliable than cheap alternatives.
It also performs consistently. There’s a high-precision pressure relief valve that keeps the pressure between 9-13 MPa, so the steering system doesn’t get damaged from too much pressure. A flow control valve keeps the oil flow steady at 2.8-3.2 L/min, so whether you’re parking (low speed) or driving on the highway (high speed), steering feels light and consistent—no heavy steering when you’re turning, no jumpy steering at high speeds.
And it’s quiet and efficient! The gears are designed like helical (twisted) teeth, plus a tight-sealing oil chamber, so it only makes noise up to 62 dB—quieter than most pumps on the market (which are around 65 dB). It also saves energy: the hydraulic system is efficient, so the engine uses 5% less power to run it compared to standard pumps. That means better fuel economy for your Chery A5.
4. How to install & keep it in good shape
Installing A21-3407010HA is straightforward, but a few steps matter:
When bolting it on, tighten the bolts to 25-30 N·m—too loose, and it’ll leak oil; too tight, you might break something.
Add Chery’s original steering oil (or oil that meets API SP 5W-30 standards) to the right level, then start the engine and let it idle for 3-5 minutes. That gets rid of air in the hydraulic system, so the pump works right.
For maintenance:
Every 10,000 km, check if A21-3407010HA is leaking oil (around the inlet/outlet or shell) or making weird noises (grinding or whistling). If yes, stop using the car and fix or replace the pump—don’t wait until it breaks down.
5. Warranty & after-sales help
A21-3407010HA comes with a 12-month or 20,000 km warranty—whichever comes first. If it has quality issues (like oil leaks, strange noises, or pressure problems) because of how it was made (not because you installed it wrong or damaged it), we’ll replace it for free.
Need help? We have tech support 24/7—call the hotline or chat online, and they’ll walk you through installation or fix problems. If you’re a repair shop or distributor buying in bulk, we’ll deliver it to your door and assign a dedicated after-sales manager to help you.
6. Who this is for & why it’s worth it
This A21-3407010HA is perfect for two groups: Chery A5 owners who need to replace their old steering pump, and auto repair shops that work on Chery cars. It’s reliable, works great, and has good after-sales support—basically, it makes sure your Chery A5’s steering stays smooth and safe, no headaches.

Product Features:
Chery A5 Steering Oil Pump (A21-3407010HA)
100% Chery A5-Specific Fit, No Compatibility Hassles
The A21-3407010HA is built exactly to Chery A5’s original factory specs—every size and connection matches the car’s original parts perfectly. You can just bolt it right on, no tweaks or changes needed at all. Unlike those one-size-fits-all pumps that often leak oil or make weird noises, this A21-3407010HA works as smoothly as the Chery A5’s original steering pump. No compatibility headaches here!
Super Durable Materials, Tough & Corrosion-Resistant
The A21-3407010HA has a high-quality aluminum alloy case with an electrophoretic coating—it keeps out moisture, dust, and chemicals from the engine bay, so you never have to worry about rust. Even better, the gears and bearings inside are made of strong alloy steel. They’re polished super precisely and heat-treated too, so their surface is tough (HRC 58-62). Under normal use, it’ll easily last over 60,000 km—way more durable than regular steering pumps.
Ultra-Stable Steering, Smooth at Both Low & High Speeds
The A21-3407010HA comes with two handy valves: a high-precision pressure relief valve and a flow control valve. The pressure one keeps things steady at 9-13 MPa, so the steering system doesn’t get damaged from too much pressure. The flow one keeps oil moving at 2.8-3.2 L/min. Whether you’re parking or turning slowly, or driving fast on the highway, the steering feels light and consistent—no heavy steering when you’re going slow, no jumpy steering when you’re speeding. Every drive feels comfy.
Quiet Operation & Fuel-Saving, Hassle-Free for Daily Use
This A21-3407010HA uses a helical gear design and a tight-sealing oil chamber, so it only makes noise under 62 dB. That’s quieter than the usual 65 dB most pumps put out—you’ll barely hear it while driving. Plus, its hydraulic system is efficient, so it uses about 5% less of the engine’s power than standard pumps. Over time, that helps the Chery A5 save more gas. No extra hassle, just good for daily use.
Easy Installation & Maintenance, Even for Beginners
The A21-3407010HA doesn’t need any complicated mods—just bolt it to the Chery A5’s original holes. Tighten the bolts to 25-30 N·m, and you won’t have oil leaks. Maintenance is simple too: check the oil level once a month; change the steering oil and clean the oil filter every 20,000 km; look for oil leaks or weird noises every 10,000 km. Follow these steps, and the A21-3407010HA will keep running steady—no constant stress about fixing it.
