Engines

Engine Cover/Air Filter Housing

The engine cover on the 2.5L engine
includes the intake air filter and part of the
system that delivers heated intake air to the
engine. The engine cover’s configuration
also lowers engine noise.

Vacuum Pump

The 2.5L engine’s vacuum pump is
mechanically driven by the timing chain and
provides power assist to the vehicle’s brake
system. The pump is driven via its cog
wheel assembly.
