Haima S5 Engine Cushion (Left-Hand) – Part No.: SA22-39-071

Let’s keep it straightforward—this isn’t just a “mirror version” of the right cushion on your Haima S5. It’s the key shock-absorbing and load-bearing part for the left side of the engine: a durable, precision-made component crafted from rubber-metal composite (a tough rubber core with embedded steel plates). Mounted between the left side of the S5’s engine block and the chassis frame, it works hand-in-hand with the right-hand cushion to act as the “engine’s left-side stabilizer.” Without it, the engine would sit lopsided, vibrate heavily on the left, and risk damaging left-side hoses or wires—ruining ride comfort and engine safety.

This left-hand (LH) engine cushion is exclusive to Haima S5—always check your vehicle’s VIN to confirm fitment! It’s tailored to the S5’s specs: its thickness and rubber hardness match the engine’s left-side weight distribution (so it won’t flatten or crack under pressure), its mounting holes align perfectly with the S5’s left engine block and frame (no forced adjustments), and its flexibility syncs with the engine’s vibration rhythm (maximizing shock absorption on the left). Grab a generic LH cushion? You’ll run into issues: wrong size (can’t install), mismatched hardness (uneven vibration), or weak steel plates (rips apart fast).

 Core Jobs: Balance Vibration, Support Weight & Protect Left-Side Parts

As a must-have for your S5’s engine stability, it does three key jobs—working with the right cushion to keep things smooth:

Dampen left-side engine vibrations: When the S5’s engine runs, left-side components (like the alternator or AC compressor) add extra shake. The cushion’s rubber core bends gently to soak up these left-focused vibrations, stopping them from spreading to the chassis and cabin—cutting down on left-side rattles, especially at idle or low speeds.

Share the engine’s weight evenly: The S5’s engine weighs 120–160kg, and this LH cushion carries a big chunk of that load. It works with the right cushion to hold the engine level (no sagging to the left when hitting bumps or accelerating hard), keeping all components aligned.

Protect left-side hoses & wires: By cushioning the engine’s small left-side movements (from heating/cooling or road jolts), it stops delicate left-side parts—like the coolant hose or alternator wiring—from being pulled or twisted. This avoids leaks or electrical issues that could lead to bigger engine problems.

This SA22-39-071 LH engine cushion only fits Haima S5—wrong fit means imbalance or damage:

Fits These: All Haima S5 variants (matches engine left-side specs, frame mounting points, and weight distribution—confirm with VIN).

Won’t Fit These:

Other Haima models: Like S7, M3, or M6—different left-engine mounting spots and weight needs (cushion can’t align).

Non-Haima vehicles: Even if similar, left-engine/frame bolt patterns are off (can’t install or work).

S5 with modified engines: Aftermarket engines have different left-side weight/mounts—original cushion can’t adapt, causing lopsided engine.

Installation & Upkeep (Pros Only—Balance Is Key!)

Installation: Must Be Done by Certified Technicians

Swapping this LH cushion isn’t DIY—misalignment breaks balance:

Prep: Techs lift the S5 safely, use a specialized jack to support the engine (so it doesn’t drop when removing the old LH cushion), then remove bolts connecting the old cushion to the left engine/frame.

Remove old cushion: They pull out the worn unit, clean left-side mounting surfaces (wipe oil/rust/dirt), and check for left-engine/frame damage.

Install new cushion: They line up SA22-39-071 with left mounting holes, bolt to Haima’s exact torque (too tight crushes rubber; too loose shifts left), then lower the engine gently—ensuring it sits level with the right cushion.

Test: They start the engine to check for even vibration, test drive to confirm no left-side rattles or engine tilt, and verify no warning lights.

Maintenance: Easy Checks to Keep Left-Side Stability

Inspect left-side rubber: Every 30,000km, check if the LH cushion’s rubber is cracked, hardened, or leaking (old rubber loses left-side shock absorption). Replace immediately if damaged.

Tighten left bolts: Have techs check LH cushion bolts during oil changes—loose bolts cause left-engine wobble and uneven wear.

Keep oil off left rubber: Engine/gear oil eats rubber—wipe up leaks near the LH cushion right away to avoid damage.

Watch for imbalance warnings: If you feel left-side vibration in the steering wheel, hear left-cabin rattles, or notice the engine tilts left, the LH cushion is worn out.

Summary: Haima S5 Left Engine Cushion (SA22-39-071)

This is an exclusive left-hand (LH) engine cushion for Haima S5 (confirm VIN for fitment). Made of rubber-metal composite (tough rubber core with embedded steel plates), it’s mounted between the S5’s left engine block and chassis frame, working with the right cushion for balance.

Its core functions: Absorb left-side vibrations (from parts like alternators/AC compressors) to reduce cabin rattles; share the 120–160kg engine’s weight to keep it level (no left sagging); protect left-side coolant hoses and alternator wiring from twisting/damage.

It only fits Haima S5— incompatible with other Haima models (e.g., S7, M3/M6), non-Haima vehicles, or S5 with modified engines. Installation needs certified techs (engine jack support & torque control). Maintenance involves 30,000km rubber checks, left-bolt tightening, oil leak prevention, and addressing left-vibration/rattle warnings. Original parts are essential—aftermarket ones cause imbalance, poor fit, or short lifespans, risking engine damage.
