Fuel Injection: It Keeps Getting Better for San Diego Drivers

San Diego residents know that engines need to burn fuel to operate. Fuel is pumped from your fuel tank to your vehicle engine where it is squirted—or injected—into your engine's cylinders. This is the function of the fuel injectors.There are two ways to inject fuel into an engine. Fuel needs air to burn, so in the first method, fuel is injected into a port and allowed to mix with airbefore it is drawn into the cylinders. In the second method, fuel is injected directly into the cylinders and mixes with air after it enters the vehicle engine.Direct injection engines burn fuel more efficiently than conventional vehicle engines. Some models can deliver the power of a V8 with the economy of a V6.For example, in one family of engines, the conventional version (a V6) delivers about 250 horsepower. The direct injection version delivers over 300 horsepower and gets about the same gas mileage. The turbocharged version delivers 350 horsepower ... read more

Trip Inspection at John's Automotive Care in San Diego

San Diego area drivers love their vehicles. And one of the most enjoyable things about them is taking a road trip. Freedom from daily schedules, new sights and the open road – it's great! But there's nothing like vehicle trouble to bring the fun to a grinding halt.

Now San Diego drivers can't always avoid problems, but you can take steps to reduce the probability of getting sidelined on your trip.

Will it be dusty? Prepared with answers to these questions, you can schedule a trip inspection at John's Automotive Care in San Diego to help you

Serpentine Belt Service at John's Automotive Care in San Diego

If you've ever heard a squealing sound under your vehicle hood, chances are it was your serpentine belt. More importantly, the belt powers the alternator. The alternator creates electricity that's used by your vehicle's electrical systems and also charges the battery. Without the alternator, the battery will go dead after a short distance.The serpentine belt may also run the pumps for both the power steering (some are electric) and power brakes (some use vacuum boost).And, on most vehicles, the serpentine belt powers the water pump. The water pump circulates coolant through the engine to keep it within optimal operating temperatures. On some San Diego vehicles, the water pump is powered by the timing belt instead of the serpentine belt.When they understand what it does, San Diego drivers realize that if it breaks, it affects a lot of systems. That's why vehicle manufacturers outline recommended replacement guidelines in the owner’s manuals. If thi ... read more
