Belts and Hoses
The timing belt is a notched
rubber belt that allows the crankshaft to turn the camshaft. The camshaft opens
and closes the valves in synchronicity with the movement of the pistons. Thus
the name, “timing belt.” A timing belt may also be called a Gilmer belt or a
camshaft drive belt.
If your timing belt breaks,
your engine will stop working, stranding you wherever you may be. Even worse,
it could cause major engine damage. That’s why it’s important to have your
timing belt regularly inspected.
We’ll look for two
things—wear and slippage. Cracks or stripping indicate it’s time for belt
replacement. If the belt is loose or it’s slipped, the valves could open at the
wrong time and be struck by the pistons, causing major damage.
Warning sounds include a
slapping noise coming from your engine. This indicates a slipped belt.
Generally, timing belts
should be replaced every fifty to sixty thousand miles.
Serpentine belts, also known
as drive belts, provide power to the air conditioning compressor, power steering
pump, cooling fan, air injection pump, and more.
If your serpentine belt
breaks, all of the engine parts it is powering will stop working. Your engine
could overheat and be damaged. It’s very important to have your serpentine belt
We’ll look for cracks, wear,
and stripping—all signs your serpentine belt is in danger of failing. Like the
timing belt, it’s recommended to have your serpentine belt inspected every time
you have your oil changed.
Warning sounds include a
screeching noise coming from your engine, especially during start-ups on cold
mornings or on sharp turns.
Studies have shown that
serpentine belts most often fail between 36,000-50,000 miles. Most experts
recommend you have your belt replaced earlier.
Coolant hoses include the
upper radiator hose, the lower radiator hose, heater hoses and in some cars the
Hoses provide a flexible
connection for coolant flow between the engine and the radiator and the engine
and the heating block.
We recommend you have your
vehicle hoses—and accompanying clamps—inspected twice a year. Tiny cracks can
form from the inside that can eventually lead to a burst hose and overheated
The electrical systems of
today’s cars are complex. Your alternator, starter, ignition and battery are all
crucial to your cars performance and, more importantly, its safety. More and
more of today’s vehicles are being controlled by onboard computers. The
electrical system is more important than ever. Call Mobile Auto Repair San
