The technicians at John's Automotive Care know your serpentine belt drives important engine accessories like your alternator, air conditioning compressor, and power steering. In some cars it may also power the power brakes or water pump. The serpentine belt is powered by the engine and winds around pulleys and the accessories. Some cars in San Diego have two serpentine belts. The serpentine belt, the belt tensioner (which maintains the appropriate tension on the belt) and the idler pulleys are together known as the accessory drive system.Now your serpentine belt and the belt tensioner will just wear out over time – that’s why your vehicle manufacturer has a scheduled belt replacement interval. The team at John's Automotive Care in San Diego can inspect your serpentine belt for wear and get it replaced if it’s time.Give us a call.John's Automotive Care6267 Riverdale StSan Diego, CA 92120619-280-9315 ... read more

Today in our John's Automotive Care blog, we're going to talk about following recommended service intervals. Your vehicle isn't the only aspect of your life with recommended intervals: What about six-month dental cleanings and regular physical exams? Then there's laundry, mowing the lawn, paying your electric bill, changing your furnace filter - you get the idea.Now, what would happen if you didn't follow these intervals?For one thing, your teeth may get more cavities. You might not discover health issues that benefit from early detection and treatment. And you'd have to wear dirty clothes, be embarrassed by your overgrown lawn and have your power shut off.We all realize there are some things in life that we have to take care of regularly. If we don't, there are negative consequences. Our quality of life diminishes and it inevitably costs more money.Have you ever wondered, "How often should I bring my car in for scheduled maintenance?"  ... read more

San Diego drivers may have an alignment problem if their car drifts or pulls to one side, the steering wheel's off center, they notice uneven tire wear or the car doesn't feel like it handles right as they drive down San Diego, CA, streets and roads.When all of a vehicle's wheels are lined up exactly with each other, your wheels are in alignment. Running into potholes, smacking a curb or other objects around San Diego are great ways to knock a car out of alignment. Then one or more of your wheels start pulling in a slightly different direction and the problems begin.The team at John's Automotive Care in San Diego wants you to know that driving for an extended time when your car is out of alignment causes your tires to wear unevenly and excessively. Sometimes the tire can be worn so badly that it will fail.At the very least, those who drive with wheels out of alignment will have to replace their tires sooner. You could end up with premature wear to your suspension system, which can ... read more

Hello San Diego! Did you know that the first federally-mandated emissions control device was introduced in the 1960's? The Positive Crankcase Ventilation valve, or PCV valve, has been installed in CA vehicles since 1964 and represents the first legislation by the United States government to regulate harmful emissions as well as to improve performance in the country's vehicles.The PCV valve, as you can probably guess, is located on the crankcase. The crankcase is the lowest part of a vehicle's engine. It houses the crankshaft and the engine oil. The crankshaft connects to the pistons that power the engine.Pistons are pushed down when fuel is burned in an engine. This causes the crankshaft to rotate, which sends power to the transmission.  It ultimately turns the axles and causes the vehicle to move. Some of the gases released by the burning fuel squeeze around the pistons and down into the crankcase.If the escaped gases mix with the engine oil in t ... read more

Modern San Diego vehicles have several computers on board that control all kinds of things like engine functions, transmission shifts, traction control, anti-lock brakes, stability control, emissions – and on some vehicles, even steering, braking and the throttle.Think about that for a minute – things that used to be controlled by simple mechanical connections now have electronic controls that rely on computers, software and sensors. It's no wonder that when something goes wrong with their vehicle it can be pretty complicated for San Diego drivers to track down the source of the problem.To help your service advisor at John's Automotive Care figure out what's wrong, your vehicle is equipped with on-board diagnostics. The Check Engine light comes on to tell you there's a problem and the engine management computer stores a trouble code. Your friendly and knowledgeable John's ... read more

Most CA auto owners know that their vehicles need regular preventive maintenance like changing the oil and filters, rotating the tires and refilling the washer fluid. But did you know that your air conditioning system needs routine maintenance as well? Taking care of your air conditioning system can extend its life and prevent costly repair bills.Why is it important for San Diego area drivers to get routine maintenance on their air conditioning system? First, the refrigerant contains an added lubricant. As the refrigerant circulates through the air conditioning system, its parts are lubricated. This constant lubrication keeps the parts functioning well. But over time, this lubricant is used up, and without it, the parts will eventually seize up and fail.San Diego folks should understand, however, that the air conditioner will continue to pump out cool air even without the lubricant, so you won't know the syste ... read more

Diesel engines have been used extensively in Europe and Asia for many years. They haven't been as common in the San Diego area because of the high sulfur content in our diesel fuel. But the government is now mandating lower sulfur content and, as a result, we are going to see more San Diego diesel-fueled vehicles on the road, especially in passenger cars and SUV's.Diesels are popular in CA because they get better fuel economy than gas-powered engines. They also last longer. Modern diesel engines are quiet and powerful. And if you associate diesel engines with black smoke, then you're not up with the times. That smoke is a thing of the past.Diesels don't produce any more pollutants than gasoline engines. The pollution standards for diesel-powered vehicles are as strict in CA as for other vehicles.Also, diesel engines can run on bio-diesel fuels as well as fossil fuels. Diesel fuel can be produced from vegetable oil or from cellulosic w ... read more

The crankcase is the lower part of the engine where the crankshaft is housed and where the engine oil lives. The crankshaft is connected to the pistons that power the engine. When you are diving around San Diego, fuel is burned in your vehicle engine, it pushes the pistons down and the crankshaft rotates and sends power to the transmission. Some of the explosive gases from combustion squeeze past the pistons and down into the crankcase.Now this gas is about 70% unburned fuel. If it were allowed to remain in the crankcase, it would contaminate the oil and quickly turn it to sludge. Sludge is like Vaseline and clogs passages in the engine, leading to damage. Also, the pressure build up would blow out seals and gaskets. So in the old days, there was just a hose that vented the crankcase out into the air. Obviously, not good for our air quality in San Diego, CA.Enter the PCV valve. It's a small, one-way valve that lets out the gases from the crankcase and routes them back into th ... read more

People in San Diego have been hearing a lot about higher oil change intervals these days. Maybe you're wondering: What are the key issues?Some new vehicle manufacturers are now recommending much higher oil change intervals than they have in the past. As much as 5,000 to 8,000 miles (8,000 km to 13,000 km) or more. This practice came under scrutiny when four of the largest new vehicle manufacturers announced that owners like those in San Diego were experiencing engine damage resulting from these higher oil change intervals.The manufacturers' standard oil drain service for particular vehicles was scheduled at around 7,500 miles/12,000 km. People following these recommendations were experiencing engine damage. It turns out that oil sludge was building up. This caused small oil passages to clog and engine parts to fail.What causes oil sludge? It's a factor of time and mileage. There are hot spots in every engine that cause oil burn off that leads to sludge ... read more
