Winter Car Care

Written by Kevin Schappell

Asrepparttar weather turns colder, it is time to think about your car for a second. A little preparation can go a long way to making your winter travels a lot safer. Here is a checklist to get you started. 1.Checkrepparttar 102758 antifreeze. The freezing point can be checked with a simple tool available at any auto parts store. Make sure you checkrepparttar 102759 antifreeze when it's cool. Opening a hot radiator can be a dangerous thing. 2.Checkrepparttar 102760 air pressure in your tires. Asrepparttar 102761 air gets cooler pressure drops in your tires. Maintaining your tire pressures will reward you with higher gas mileage and longer tire life. 3.Make sure you haverepparttar 102762 following items in your car. - Ice Scraper

The Exhaust System

Written by Kevin Schappell

Your car's exhaust system carries awayrepparttar gases created whenrepparttar 102757 fuel and air are burned inrepparttar 102758 combustion chamber. These gases are harmful to humans and our environment. A frequent check of your exhaust system is a must to provide for you and your family's safety. Make sure there are no holes inrepparttar 102759 exhaust system or inrepparttar 102760 passenger compartment where exhaust fumes could enter. Let's begin by listingrepparttar 102761 parts ofrepparttar 102762 exhaust system and their functions. Exhaust manifold: The exhaust manifold attaches torepparttar 102763 cylinder head and takes each cylinders exhaust and combines it into one pipe. The manifold can be made of steel, aluminum, stainless steel, or more commonly cast iron. Oxygen sensor: All modern fuel injected cars utilize an oxygen sensor to measure how much oxygen is present inrepparttar 102764 exhaust. From thisrepparttar 102765 computer can add or subtract fuel to obtainrepparttar 102766 correct mixture for maximum fuel economy. The oxygen sensor is mounted inrepparttar 102767 exhaust manifold or close to it inrepparttar 102768 exhaust pipe. Catalytic converter: This muffler like part converts harmful carbon monoxide and hydrocarbons to water vapor and carbon dioxide. Some converters also reduce harmful nitrogen oxides. The converter is mounted betweenrepparttar 102769 exhaust manifold andrepparttar 102770 muffler. Muffler: The muffler serves to quietrepparttar 102771 exhaust down to acceptable levels. Remember thatrepparttar 102772 combustion process is a series of explosions that create allot of noise. Most mufflers use baffles to bouncerepparttar 102773 exhaust around dissipatingrepparttar 102774 energy and quietingrepparttar 102775 noise. Some mufflers also use fiberglass packing, which absorbsrepparttar 102776 sound energy asrepparttar 102777 gases flow through. Exhaust pipe: Between all ofrepparttar 102778 above mention parts isrepparttar 102779 exhaust pipe which carriesrepparttar 102780 gas through it's journey out your tail pipe. Exhaust tubing is usually made of steel but can be stainless steel (which lasts longer due to it's corrosion resistance) or aluminized steel tubing. Aluminized steel has better corrosion resistance than plain steel but not better than stainless steel. It is however cheaper than stainless steel. Common Problems: Wellrepparttar 102781 worst enemy of your exhaust system is corrosion.... or more commonly known as rust. Rust is caused by moisture reacting withrepparttar 102782 iron inrepparttar 102783 steel and forming iron oxide. Moisture, or water vapor is present inrepparttar 102784 exhaust as a by-product of combustion andrepparttar 102785 catalytic converter. Moisture can also come fromrepparttar 102786 outside inrepparttar 102787 form of rain. Short trips in your car can shortenrepparttar 102788 life of your exhaust system. When you shut down your engine whatever water vapor is inrepparttar 102789 pipes condenses and turns back into a liquid. On a short triprepparttar 102790 water never has a chance to get hot enough to turn back into water vapor and just stays inrepparttar 102791 system and rusts awayrepparttar 102792 pipes. If you drive for short distances consider replacing your exhaust system with stainless steel whenrepparttar 102793 plain steel one rusts through. If you drive more than 15 miles at a time then you should not have to worry about this.
