Ignition / Spark / Coil


Does your vehicle’s engine die abruptly after driving around Costa Mesa for a while? Does your car ever have trouble starting? Does it stall, misfire, backfire, or get worse gas mileage than it used to? If you’ve noticed any or all of these symptoms, you may have a failing ignition coil or coil pack. (Unless you drive a diesel - diesel engines do not need an ignition system, since they rely on compression to ignite the air/fuel mixture.) 

Your vehicle’s ignition coil, also known as a spark coil, is an induction coil in your car’s ignition system which transforms the battery’s low voltage into thousands of volts which are needed to create an electric spark in the spark plugs to ignite the fuel. Ignition coils can have either an internal resistor or an external resistor or resistor wire, which serves the purpose of limiting the current flowing into the coil from the car’s battery. They also have another high voltage wire which goes from the ignition coil to the distributor, and wires from the distributor to each of the spark plugs, called spark plug wires or high tension leads. Most ignition coil systems today use a power transistor to provide pulses to the ignition coil.

Wheel Bearings


You’ve heard of the expression “drive it til your wheels fall off” - but did you know that, if you neglect your wheel bearings, that’s actually a possibility? If you don’t take care of your wheel bearings, they could fail completely and lock up the wheels they serve, leading to loss of control or even your wheel actually falling off.

To understand why your bearings are so serious, first we must know what a wheel bearing is. A wheel bearing is a set of steel balls held together by a metal ring called a race. They help your vehicle’s wheels spin fast with as little friction as possible. On cars, the wheel bearing rides on a metal axle shaft and fits tightly inside the hub, which is the part that holds the lug bolts used to bolt each wheel onto your car.

Oil change - conventional or synthetic?


Your ExpeTec Automotive Service Advisor in Costa Mesa might ask you every time you get an oil change - conventional or synthetic? He might tell you that synthetic is better - and almost always more expensive - but you probably don’t know why. Is there really a difference, or is he just trying to squeeze more money out of you?

The fact is, there are many substantial differences between conventional and synthetic motor oils. They both start as crude oil pumped from the ground, but that is essentially where the similarities end.

Synthetic oil is not only refined, but distilled, purified, and further refined into smaller, more basic molecules. This not only removes more impurities from the crude oil, but lets individual molecules in the oil be tailored to the needs of your engine. These customized molecules provide higher levels of performance and protection than conventional oils, resulting in a less stressed, longer-lasting engine. Synthetic oils also typically have more additives to help them work better.

Home Auto Maintenance

One of the most important things you can do as as car owner is Preventative maintenance to keep your car in good shape and save money on big future repairs. But preventative maintenance is a broad category. What exactly are some of the universal things within this category that you can do at home on your own?

First of all, read your owner’s manual. No matter what vehicle you drive, your regular maintenance schedule is inside of it. It will tell you useful information such as how often you should change your oil, what type of oil to use, what grade of gasoline is recommended, what kind of filters the car uses, various belts and other parts, and much more. If you bought a used car and it didn’t come with a manual, this website has one for just about any car: . It is important that you follow the manufacturer’s recommendations for what type of oil and gas to put into your car, because using the wrong kind can potentially void your warranty and cause extensive damage over time.
