Mercedes-Benz G63 AMG Service (46,515 KM · Sri Damansara)

This Mercedes-Benz G-Class G63 AMG arrived at 4M Carcare with 46,515 KM on the odometer for a full inspection and servicing session. The G63 is Mercedes-AMG's flagship off-road performance SUV — powered by a hand-built 4.0L twin-turbo V8 producing over 580 hp. High performance demands precise maintenance, and the owner brought it to us for a thorough check and component refresh.

Ignition Plug Coil ×2 — The ignition coil converts low-voltage battery power to the high voltage needed to fire the spark plug. On the G63's V8, a weak or failing coil causes misfires under load, rough idle, and increased fuel consumption. Two coils were replaced as part of this service.

Ignition Spark Plug ×8 — The G63's V8 runs 8 spark plugs. Factory spark plugs on AMG engines are typically iridium or platinum-tipped for longevity and consistent ignition performance. All 8 were replaced to ensure even combustion across all cylinders and restore peak engine response.

Oil Separator LH & RH ×2 — The oil separator (also called PCV oil separator or crankcase breather) separates oil mist from crankcase blow-by gases before they re-enter the intake. On AMG engines, a faulty oil separator causes increased oil consumption, smoke from the exhaust, and carbon buildup in the intake. Both left and right separators were replaced.

Wiper Tank Motor & Lower Rubber — The windscreen washer tank motor pumps washer fluid to the front jets. A worn motor gives weak or inconsistent spray. The lower wiper rubber was also replaced to restore clean wiping performance — critical for visibility in Malaysian rain conditions.

Coolant — AMG engines run hot. Coolant degrades over time, losing its anti-corrosion additives and heat-transfer efficiency. Fresh Mercedes-spec coolant restores proper thermal management and protects the aluminium cooling system components from internal corrosion.

Fuel Hose — Fuel hoses deteriorate with age and heat cycling. Cracked or brittle fuel hoses are a fire safety risk and can cause hard starting or fuel pressure issues. Replacement ensures a safe, sealed fuel delivery system.

Sealant Gum — Applied at critical gasket and sealing surfaces identified during inspection to prevent oil or fluid seepage at joints.

Injector with Nozzle No. 2 — Cylinder No. 2's injector was found to be delivering inconsistently, likely causing a slight misfire or uneven power delivery. Replacing the full injector assembly with nozzle restores correct fuel atomisation and combustion balance across all 8 cylinders.

The G63 AMG uses Mercedes-AMG-specific components throughout — from AMG-tuned suspension to the hand-assembled M177 V8 engine. Using the wrong parts or incorrect torque settings on this vehicle can cause serious issues. At 4M Carcare, we work with proper diagnostic tools capable of reading AMG-specific fault codes, and we source parts to Mercedes specifications.

Being a SATA Champion Store means every task — from torquing spark plugs to removing injectors — is done with calibrated, professional-grade tools. The G63 owner can drive out knowing the job was done right.
