When Are Your Tires Worn Out?

  Hey San Diego area drivers, are your tires worn out? What is the standard for our CA streets? How can you tell on your vehicle?While there may be legal requirements for the San Diego area, there are safety concerns that go beyond meeting minimum replacement mandates.Two-thirty-seconds of an inch is the depth of the tire tread wear indicator bars that US law has required to be molded across all tires since August 1, 1968. When tires are worn so that this bar is visible, there's just 2/32 of an inch – 1.6 millimeters – of tread left. It's that level of wear that's been called into question recently.We're referring to the tread depth on a tire, it can't move surface water out of the way and you start to hydroplane.In a safety study, a section of a test track was flooded with a thin layer of water. If you laid a dime on the track, the water would be deep enough to surround the coin, but not enough to cover it.A car and a full-sized pick-up accelerated to ... read more

Gear Up: Transmission Service at John's Automotive Care in San Diego

The transmission system in your vehicle allows you to change gears. Lower gears are power gears. They get your vehicle moving and get it up hills. Higher gears get the vehicle up to speed and get it rolling faster. If you have a standard transmission, then you have to do the work of shifting gears yourself. But with an automatic transmission, the vehicle shifts gears on its own. It automatically starts out in low gear and automatically shifts to high gears as it gets rolling. Again, it will automatically shift to a lower gear to climb hills or when you need a burst of speed.How does it know when to change gears? Today's automatic transmissions are computer-controlled. The computer gathers information about what the vehicle is doing and changes the gears as needed.Automatic transmissions are becoming more sophisticated all the time. More gears, or “speeds,” are being added. Almost all vehicles have at least four speeds. Five or six is common. Some are even increasing to sev ... read more

John's Automotive Care Maintenance Tips: The Belt Goes On

John's Automotive Care Maintenance Tips: The Belt Goes On

All San Diego service advisors know that without the alternator, the battery will go dead in a few miles. The serpentine belt may also run the pumps for both the power steering and power brakes. And on many vehicles, the serpentine belt powers the water pump. The water pump circulates coolant through the engine to keep it within normal operating temperatures. (On some vehicles, the water pump is powered by the timing belt instead of the serpentine belt.) So you can see the serpentine belt does a lot of work. And it if breaks, it affects a lot of systems. That's why your vehicle manufacturer and your service advisor at John's Automotive Care have recommended that it be changed every so often so that it doesn't fail.Your friendly and knowledgeable John's Automotive Care service advisor can perform a visual inspection of the belt to see if it has any cracks that signal the belt could fail soon and will m ... read more

Automotive Tips from John's Automotive Care: A Broken or Damaged Timing Belt

The timing belt rotates the cam shafts which open and close the valves that allow air, fuel, and exhaust to flow through the engine as it powers your car when you drive around San Diego.An old timing belt can lose a “tooth” in the belt allowing it to slip. The engine could stop or misfire. Timing belt slips – or a broken timing belt – can be disastrous on some engines. In “interference” engines, open valves can get in the way of the piston when the timing belt breaks or slips. When that happens one or more valves can be bent requiring expensive engine repairs.It is important for San Diego drivers to replace their timing belts as recommended in their owner’s manual to avoid unnecessary breakdowns. Ask the team of professionals at John's Automotive Care in San Diego if it’s time for your timing belt to be replaced. John's Automotive Care6267 Riverdale StSan Diego, CA 9212061 ... read more
