Serpentine Belt Service at John's Automotive Care

Most San Diego folks occasionally have days when they've got a bunch of errands to run. Yesterday was my day off and I needed to fill the gas tank, pick up some groceries at my San Diego market, swing by the ATM and get the kids from school. I could have made four trips . . . but that would have been totally inefficient. Instead I got unusually organized and planned my stops. I hit the ATM first and got gas next. Then I went to the supermarket and picked up the kids on the way home. I was proud of my wise use of time and money.What does this have to do with your car? Well, back in the day, each of your engine's accessories, like the alternator and air conditioner, were powered by separate belts. A vehicle might have five or six belts. These days, vehicles have a single belt to run all the accessories. It's called the serpentine belt. A pulley attached to the vehicle engine's crank provides the power to turn the serpentine belt. On the engine in the video, the first accessory in line i ... read more

Taking the Heat (Heater Hose Maintenance/Repair)

If you have an internal combustion vehicle, you know it has a lot of hoses that carry various fluids.  And if you have a heater in your vehicle, you'll have heater hoses. A heater hose connects to and from the engine so some coolant can be circulated through a little radiator called a heater core.  In cold weather, that heater core acts as a heat exchanger to heat up your cabin. Even in the hot weather, the heater hoses can prove problematic.  That's because they may remain pressurized even though you're not running your heater.  Heater hoses are made out of tough materials since they must handle heat and pressure.  But even the durable rubber, plastic and metal they are made out of can crack or leak from years of use.  That means coolant can be sprayed out into the engine compartment or leak onto a driveway or garage floor.  You may be able to see a puddle of coolant under your vehicle or perhaps smell the odor of the coolant under the hood.  So ... read more

Greeted by a Screech (Loud Noise when Starting Vehicle)

No one likes to be greeted in the morning by having someone screech at you.  The same goes for a loud, high-pitched noise your vehicle greets you with every time you start the engine.  If you're wondering if that's normal, no, it isn't.  And it is worth getting checked out.  The good news is that it might be nothing serious.  Then again, it may be. The first things to suspect any time you hear a high-pitched sound coming from the engine are belts.  They have tension on them and they're trying to turn lots of different pulleys, pumps and other equipment the engine needs to work properly.  The noise could come from the belts starting to wear out and dry out. If one of those belts breaks at an inopportune time, not only can it strand you somewhere, the damage to the engine could be very expensive to fix. Other things that will cause a high-pitched sound are the pulleys and tensioners.  The tensioners keep the right amount of pressure on the belts an ... read more

The Edible Engine

You may have had a friend whose vehicle was the victim of hungry rodents.  After all, mice, rats and squirrels—even rabbits—have been known to gnaw on wires in engine compartments, causing vehicle electrical systems to go haywire.  They can disable a vehicle completely and be very expensive to fix. In 2017, some drivers noticed their vehicle's wiring was being chewed and found out the automaker was using a relatively new material for covering their wires: soy.  Many of the repairs to their new vehicles weren't covered under warranty by the manufacturer when it was discovered rodents were eating the wiring.  So the owners filed a class action suit, saying the soy covering was essentially baiting the critters.  The automakers tell a different story, saying mice, rats and squirrels have been chewing through wire insulation long before it was made out of soy.  Regardless of what the insulation is made of, vehicle owners should make sure rodents are ... read more
