Primary transmission
Primary transmission is provided by a single-profile belt from the crankshaft to the gears of the exhaust camshaft of each cylinder bank through two support rollers and a tensioner.
The timing belt tension is adjusted using an eccentric tensioner mounted on the right front side of the cylinder block.
Secondary transmission

| 3 | - | Intake camshaft |
| 4 | - | Exhaust camshaft |
| 5 | - | Tensioner striker |
Secondary drive is provided by two short cross chains that transmit torque from the exhaust camshaft gears to the intake camshaft gears. The chains are located at the rear of the right bank of cylinders and at the front of the left bank of cylinders. This allows the primary belt drive of the camshafts at the front of the engine to be simplified and made shorter.
Each cross chain is equipped with an automatic tensioner, which acts directly on the chain via a guide. The tensioners are located between the exhaust and intake camshafts at the front or rear of the cylinder head, depending on the cylinder bank.

The plastic timing cover is attached to the front wall of the cylinder block and the cylinder heads with 16 bolts. There is a rubber seal under the cover.
