The term “tune-up” actually applies only to older cars without electronic ignition (before 1981). On these vehicles a tune-up would generally be required every 15,000 – 20,000 miles and consisted of replacing the spark plugs, ignition contact points, rotor and distributor cap and adjusting the ignition timing as well as the carburetor.
On modern vehicles equipped with electronic ignition, fuel injection and computer controls, the term “engine performance maintenance” is a more accurate term. A “tune-up” for these newer vehicles is an orderly process of inspection, computer diagnosis, testing and adjustment to maintain peak engine performance, maximum operating efficiency and low exhaust emissions. |

If you are driving at normal highway speed and the vehicle starts to overheat, turn off the air conditioner, turn on the heater and immediately pull over to the shoulder. Odds are if the vehicle starts to overheat at highway speed, there is a problem in the cooling system such as low coolant, a clogged radiator or a broken drive belt or burst hose. Once at the shoulder, shut off the engine, open the hood and let the engine cool down – 20 minutes minimum. Once any overboiling stops and the engine has cooled, look for obvious signs of trouble. |

Before the question can be answered as to why there are so many different types of spark plugs, we first need to examine how a spark plug works. Spark plugs need 5,000 to 40,000 volts from the ignition coil before a spark will jump across its electrode gap. It takes a lot of volts to push the spark across the gap because air doesn't conduct electricity unless it is ionized first. The spark jumps from center electrode to side ground electrode. The reason why a plug fires from center electrode to side ground electrode, instead of vice versa, is because it's easier for a spark to originate at a hot electrode than a cooler one. |

Torque-to-yield (TTY) head bolts are designed to stretch when used. Once stretched, they are not as strong as before. Consequently, they cannot provide the same amount of clamping force and may break or shear off if reused. The TTY bolt-tightening procedure is designed to provide a better, more uniform seal. On the factory assembly line, sophisticated torquing equipment is used to tighten head bolts beyond their yield point. This stretches the bolt slightly and evens out the loading so each bolt provides almost exactly the same amount of clamping force on the head gasket. |
