List of interference (bends engine valves) vs. non-interference engines.
The Camshaft Timing Belt (or Cambelt) connects
the crankshaft at the bottom of the engine with the
camshafts at the top of the engine. The teeth on the
belt and on the crankshaft and camshaft sprockets
ensure that the valves open and close at exactly the
right times. The intake valve opens to allow fuel and
air into the cylinder, then closes as the mixture is
compressed then ignited, then the exhaust valve
opens to allow the waste gasses out.
Cambelts are lighter, quieter, and more fuel efficient
than metal timing chains, but require replacement at
manufacturer recommended intervals. If the belt
breaks when the engine is running, it is possible that
valves can become stuck in the open position, and
bent by contact with the piston.
During the Cambelt replacement, the hydraulic
tensioner that keeps the belt tight should also be
replaced to prevent future failure as a result of
reusing worn parts.
On many vehicles, the pump that circulates coolant
or antifreeze around the engine is also driven by the
cambelt. Replacing this pump at the same time as
the cambelt avoids the risk of the pump leaking or
seizing as a result of worn bearings.
