Tune-Ups, how and when!

You may have heard of getting your car a tune-up, but what exactly does that mean? Why is it necessary? Is it really in fact necessary to keep your car running well?

Most basic tune-ups include performance checks - battery voltage, compression tests, vacuum tests, an ECU scan, exhaust emissions, idle speed check, ignition timing check, and a visual inspection of hoses, belts and fluids. Any parts that seem off are further inspected and repaired or made known to the owner.

Your vehicle’s owner’s manual should give you recommended tune-up intervals, but even if it says that your vehicle does not need a tune-up very often, there are several signs that you should watch out for to check that your vehicle is working as efficiently as it can. If you drive in heavy traffic or tow a lot of weight, more strain will be placed on your engine and it may need to be tuned more often.

We're Talkin' Head Gasket Repair!


They are two of the most dreaded words in anybody’s automotive vocabulary - head gaskets. You may not know what exactly a head gasket is or what it does, but you most likely have heard that it is a very expensive repair. Well this week, we’re gonna teach you how to recognize early signs of a leaking head gasket and how to prevent the problem from occurring in the first place, as well as what to do if you realize that your head gasket has started leaking.

A blown head gasket may cause a number of different symptoms. Coolant in the engine oil, overheating, an engine misfire or oil leaking from the engine could all be symptoms.

Each of these symptoms could also have other causes and an actual blown head gasket may show none of the above symptoms, but a head gasket would be the most common cause.

Head gaskets may actually fail in several different ways, and each way can give different symptoms. The symptoms that you see will depend on how and where exactly your head gasket has failed.

Radiator Repair

Overheating is one of the biggest dangers to your engine, especially in the hot Orange County summer. With temperatures inside of your engine in excess of 2000 degrees fahrenheit, there is a huge amount of heat to deal with. If you notice that your car’s temperature gauge is creeping higher than usual, puddles of coolant are pooling underneath your car, or your engine is smoking from under the hood, it may be time to come to ExperTec Automotive in Huntington Beach for an inspection.

A functional cooling system circulates antifreeze/coolant, dissipating engine heat, and keeping your engine from overheating to destructive temperatures. If your engine overheats it can easily damage itself by deforming components or blowing a head gasket, all of which can quickly lead to engine failure. These are already expensive repairs, and an entire engine replacement would cost thousands of dollars in even the cheapest car.

What Types of Cars Need Drivelines

This week on ExperTec of Huntington Beach’s Cars 101 blog, we’ll go over the parts responsible for getting the power from your engine to spin your wheels.

All automobiles, front, rear, or all wheel drive, have a driveline. The driveline is the system responsible for delivering power from the engine to the drive wheels.

A vehicle’s driveline turns your axles, which turns your wheels. There are different types, depending on what your vehicle’s drive wheels are. A car’s driveline connects to the transmission and differential through a series of universal joints.

Most universal and CV joints are sealed, and do not require periodic lubrication. However, it is important to have them inspected anytime your car is on a lift for service. Any crack or leak in one of these joints can end up severely damaging your vehicle.

Are You Feeling The Heat?


Here on the Expertec Automotive blog, we have covered several essential maintenance and repair topics already. Most of the parts that we have covered are essential to the function or control of the vehicle, and their failure can result in fire or loss of control, easily causing an accident. However, there are other nonessential parts of your car that can also be harmful if neglected. One system that may seem harmless but can actually cause serious harm to your health if neglected for long enough is the A/C system.

If you neglect your A/C system for long enough it can develop a condition called “black death”, which can be impossible to detect at first but cause serious illness or respiratory issues if left unattended to.

Black death develops inside of the A/C compressor after the refrigerant starts to deteriorate. Since A/C refrigerant breaks down over time, its function will diminish, resulting in wear to your A/C system’s components, starting from the compressor, which will wear down and release fine, sharp, metal particles which will mix into the fluid and flow through the rest of your A/C system, damaging the rest of its components and function gradually. The best way to avoid black death is to have regular checkups and perform any maintenance as soon as necessary.
