21515619 Ignition Coil | Genuine Volvo Penta Part

🔧 Product Description

A genuine high-output ignition coil used in Volvo Penta spark-ignition engine systems that specify part number 21515619. It converts the low-voltage primary supply into the high voltage required to fire the spark plug reliably under compression.

🚤 Compatibility

Typically suits:

• Volvo Penta 4.3GL-P

⚙️ Key Features

• Genuine Volvo Penta ignition coil
• Designed for the specified electronic ignition system
• Produces high-voltage spark energy from the low-voltage primary circuit
• Engine-grade insulation for heat and vibration resistance
• Direct replacement for the same numbered original coil
• Engine type: Volvo Penta petrol or gas spark-ignition engine

🔌 Function

Steps up battery voltage to the high ignition voltage needed to bridge the spark-plug gap and initiate combustion at the correct time.

⚠️ Common Signs of Failure

• Engine misfire under load or during acceleration
• Hard starting or a complete no-start condition
• Weak or absent spark
• Rough idle, reduced power or increased fuel consumption
• Heat-related intermittent failure or ignition fault codes

🛠️ Service Notes

• Isolate the battery before disturbing ignition components, and never crank or run the engine with a high-tension connection left off
• Fit the coil clean and dry, with the boot, seal and terminals free of moisture and corrosion; a thin film of silicone dielectric grease inside the boot keeps damp and salt out of the connection without packing the contact itself
• Renew the spark plug the coil fires where it is due, along with any lead or boot that is hardened, cracked or showing tracking marks
• Seat the boot fully onto the plug and latch the low-tension connector properly — a partly seated coil will misfire under load even though it looks fitted
• Mount the coil securely to the figure in the workshop manual for your engine and support the harness so vibration is not carried into the connector

📦 Condition

• Genuine Volvo Penta part
• Brand new
• Supplied in original or equivalent packaging
