Wednesday, August 4, 1999 THE OAKVILLE BEAVER D5 AUTOMOTIVE A U T 6 R A Beating summer he Ironically, a liquid-cooled engine, such as the one in your everyday car, would likely overheat if it weren't for air. That's because the engine coolant travels through a radiator which is cooled by air passing through it. The process works well, provided the vehicle is moving quickly enough to have adequate air flow. But what about when the vehicle is stopped, or working hard to climb a hill with a camper in tow? The engine's fan comes to the rescue -- there are several types -- to ensure air is moving through the radiator. Several significant advances have been made in the last 20 years to better cool your engine.. Radiator and fan (top view) The fan aids cooling by forcing air through the radiator, so that cooling is still taking place, even if you're stopped. Engine and radiator Air passes through radiator Coolant flow Radiator 5 Fan blades act like the blades of a propeller, ulling air rough the tdiator to egulate the temperature of the coolant. r passes through radiator Pulley Belt-driven fixed-blade fan Blades are rigid and turned by a belt driven by the crankshaft. The faster the engine turns, the faster the fan turns. Even when the vehicle is moving fast enough to cool itself, the fan still spins, causing some drag on the engine. Some rigid-blade fans are thermostatically-controlled. In these cases, a clutch disengages the fan when cooling is not required which saves energy. Cross-section of flex fan blade Belt-driven flex fan As the term implies, the blades of a flex fan 'flex,' or flatten, as engine speed increases. The benefits are good low-speed cooling, and less high-speed drag. The blades are thin and made of stainless steel, aluminum or even fiberglass. Belt Temperature-activated electric fan Position at high speed C O P Y R I G H T W H E E L B A S E C O M M U N I C A T I O N S An electric fan -- sometimes two are used -- is turned on by the vehicle once a certain coolant temperature is reached. When the temperature returns to normal, the fan(s), made of plastic, shuts off. The fan remains off when the vehicle is moving fast enough to cool itself and causes the least drag on an engine. Electric fans allow the vehicle to remain near optimum operating temperature at all times. If you have a news tip or story idea, call the Oakville Beaver at 845-3824. r Give your car a brake Discs. Drums. Power assist. ABS. Why does life have to be so complicated? Well, it's not so bad. It all depends on friction -- the friction between the brake pad and the lining in a drum or the rotor of a disc brake, and the friction between the tires and the road. When you press down on the brake pedal, that creates pressure in the master cylinder. This is passed through the brake lines to the brakes. If you have power or power assisted brakes, you don't have to press as hard on the pedal to get the same braking effect. In a drum brake, the brake shoes inside the drum press outward against the brake lining to create the stopping force. It's an enclosed unit that's relatively inexpensive to maintain. Disc brakes are like bicycle brakes -- the calipers pinch the disc, or rotor, to create the stop­ ping force. Because of their better heat rejection, disc brakes offer up to three times more stopping power than drums. That's why most cars have discs on the front, where most of the stopping work is done, and drums on the rear. Because of the heat generated in braking, pads used to be made with asbestos. Newer metallic materials have done away with asbestos and its harmful dust. The fluid in the master cylinder is the medium that translates your pedal pressure into brake pres­ sure. It absorbs water very easily, so if you have to add fluid, use a fresh container. And use only the approved brake fluid described in your owner's manual. How do you know when it's time for a brake job? If your brakes squeal or make a grinding noise, or if you feel a lot of vibration or grabbing, it's time for a check up. If your brake pedal sinks to the floor, or feels spongy, you may be low on fluid or have a leak in the system. Car Care Canada notes that nearly half of Canadian drivers rank brake failure as their num­ ber one fear of mechanical failure. And what do they do about it? Only 20% identified brakes as a system that should be checked regularly. You should rotate your tires every 10,000 km or so to make them last. When the car is on the; hoist and the tires are off, that's an ideal time to do a little preventive maintenance and get your brakes checked. Brakes can last 60,000 km or more -- or they can need replacement after. 10,000- 15,000 km. Don't let this simple mainte­ nance item slide, or the next sound you he&r could be the crunch of a collision. Can you economize on brake jobs? Absolutely. Car Care Canada suggests a simple five point pro­ gram that could save you hundreds of dollars over the life of your car: 1. Preventive maintenance. Every 10,000 km or so, when you get your tires rotated, have your brakes inspected. 2.Don't neglect your parking brake. Using it regularly will keep the cable from seizing up, and will reduce your need for repairs. 3.Quality materials. Cheap stuff is a false economy that you'll pay more for in more fre­ quent brake jobs and inferior performance. 4 Driving techniques. Keep a buffer space between you and the car in front, and use it to slow down on the engine so you don't have to use the brakes as often. 5. System flush. Once a year, have a full brake inspection, including all lines and hoses, and replace the brake fluid with fresh fluid. 1 Winner of President's Award 5 Times Running '99 Model HYUNDAI ACCOLADES 'Thud.
