You know that long belt
that snakes around the front of your engine? Itís called the serpentine
belt. The serpentine belt is driven by the engine as it turns.
It powers your alternator, air conditioning compressor,
and power steering pump. On some vehicles it also runs
the water pump, radiator fan, and power brakes.
Sounds like a lot of important stuff doesnít it?
If your serpentine belt were to break on one of our Central Ohio
roads, your battery would die in a few miles. If it runs your fan or
water pump, your engine could overheat. And steering and braking
could be more difficult. Obviously, the best thing is to replace
your serpentine belt before it breaks.
Check your ownerís manual for when itís recommended that you replace
your serpentine belt Ė or just ask a service
advisor at Hoffman Auto Repair. We can inspect the belt as well to
see if itís in trouble.
You may have been told by a service advisor to look for
cracks in your belt to see if it needs to be replaced. Of course,
cracks are still a concern, but modern belt material doesnít crack
as often as old belts did. What we look for these days is the
thickness of the belt. There are tools available that measures the
depth of the grooves in the belt to see if it needs replacing.
A worn belt can slip or be misaligned, putting undue stress on the
accessories it runs.
Now you can imagine itís important for the belt to be tight, so
thereís a tensioner pulley on your engine that puts pressure
on the belt to keep it at the right tension. The spring on the
tensioner wears out over time so we recommend replacing the
tensioner pulley at the same time as the serpentine belt.
Replacing your serpentine belt on schedule, or when an inspection
warrants it, will keep you from an unexpected breakdown.
Radiator & Coolant Hoses
and coolant hoses are vital to keep your engine from overheating.
With time and use, hoses become brittle and weak. Don't wait for a
failed radiator or coolant hose to leave you stranded.
Upper Radiator Hose
Lower Radiator Hose
Cooling hoses should be
replaced every 5 years or 100,000 miles.
