Warm weather warnings designed to prevent troubie Now is the time to make sure your car’s cooling system will withstand the summer driving strains of higher speeds, heavier loads and extended hot-tempera- ture idling. To prepare yourself mentally, here is a list of warm weather warnings that will help keep you out of trouble. 1) Don’t worry about the engine running hotfor a short period of time, as long as the liquid coolant in the radiator does not boil. If it boil s, the radiator will lose this fluid, and you will have to stop, let the system cool and then add water before moving on. 2) Don’t stop and turn off the engine when the dashboard light Electronic 'Proxima' is high-tech masterpiece If you have ever wondered what you will be driving in 1997 or 2020, take a look at Peugeot’s crystal ball on wheels, the Proxima. This futuristic vehicle was built using technology that will be progres­ sively introduced into the cars of tomorrow. JeanDerampe, aseniorengi- neer at the automaker’s Le- Garenne research center in France, explains the idea behind the Proxima: “We call it ‘peugeo- technology.’ Instead of a wild dream, the Proxima is a synthesis of systems that are already being proven in our laboratories.” Their vision is a fully functional prototype unveiled in Los Angeles: The roof is a glass bubbles with ventilation of the four-passenger cockpit provided by solar-cell power. The electronic pilot and navigation system includesfive color video display units, managed by two central computers with 40 megabytes of memory. An anti-collision radar continu­ ously scanstheroad ahead. The radar image is displayed on a screen together with the stopping distance at the speed of travel and current road conditions. Television qameras replace rearview mirrors. Other safety features include M Safety Glass (por Heavy Duty Equip., etc.) flashes “hot” or when the temper­ ature gauge rises above its normal position. This could cause the coolant to boil. Just slow down 5 or 10 mph, turn off the air condition­ er, and, if possible, shift down one gear. This will give the engine every chance to cool off by itself. If you do stop, keep the engine running at a fast idle. This should cool it down if you haven’t lost too much coolant or broken a fan belt. You can also spray a little water on the radiator to cool it much faster, or turn on the heater, if you can stand it, to help dissipate the heat. 3)Don ’t remove the radiator cap when the engine is hot. By removing it, you will relieve the pressure in the cooling system and electronic monitoring of the tire pressures. If the pressure of one tire drops, the central computer starts a compressor to reinflate the tire. If the correct pressure cannot be obtained, the central computer will indicate the maximum speed not to be exceeded. The disk brakes are made of carbon fiber for powerful braking and high temperature stability. The anti-skid braking system prevents wheel lock. The four-wheel drive transmis­ sion is engaged only as needed. Rear-wheel drive is used until the Proxima’s computer sense that wheelspin is about to occur. The 600-horsepower V6 engine is a high-tech masterpiece. It has four valves per cylinder and two turbo-chargers. Each spark plug has its own ignition coil. Frictional losses are minimized through the use of ceramic linings on bearings and shafts. Engine management systems are computerized, includ­ ing fuel injection, ignition and 'turbocharger boost pressure. The Proxima is named after the star in the Centaurus constellation that is the closest to our sun, 4.27 light years away.

Have him inspect your vehicle, and ask that special attention be’paid to the cooling system and belts. Special oils for special engines Comparing an automative en­ gine of the ‘ 80’s to an engine of the ‘60s or ‘70s is like comparing a jet fighter to a bi-plane. Standard six- and eight-cylinder engines havegiven way to high- performance turbos and four- cylinder power plants. As engines have changed, so have their lubrication requirements. TURBO OILS According to a leading motor oil expert, Norm Hudecki, associate director of the Valvoline Automa­ tive Product Application Labora­ tory, turbo appeal is stronger than ever among today’s car buyers. “The turn-on is high-performan­ ce, obtained by harnessing the exhaust gases that normally would be nothing more than waste,” he says. These gases are usedto spin a turbine which forces a greater volume of air and fuel into lune Up And Save 0 Windshield Repairs (j) Auto Upholstery (Seat Repairs) combustion chambers. The draw­ back of turbocharging is heat. Without adequate motor oil protec­ tion, turbo shaft bearings can quickly fail, so engine oil must circulate around them. While the engine is running, the constant flow of oil lubricates and cools turbo bearings. But when the engine is shut off, oil flow stops. probably cause the coolant to boil. You also could get a hot shower. After the engine has stopped boiling, wait about 45 minutes, then check the level of coolant by removing the radiator cap. But, if the coolant starts to boil as the cap is removed, wait another 20 minutes and check it again. Don’t remove the radiator cap until the pressure is gone from the cooling system. 4) Don’t let anyone remove your car’s thermostat to correct an overheating problem. You should, of course, replace a defective thermostat, but don’t ever run without one. The thermostat keeps the engine oil clean and minimizes wear on all parts. This engine efficiency also means a cleaner exhaust and more miles per gallon of gas. In spite of the critical job performed by the engine cooling system, Gates says that it is the most neglected system in the entire automobile. And neglect of the cooling system, especially drive belts, radiator hoses and the coolant, is the main reason for engine overheating. During the “soakdown” period, which can last up to 20 minutes after the ignition is switched off, there is no provision for cooling. Turbo bearing temperatures can reach 600 degrees before beginn­ ing to cool down. Ordinary motor oils can literally “cook” atthese temperatures, Continued on page 24 ) Convertible Tops ' (Boat Tops) tx Oil and Oil filters Quaker State Oil 10W30 a 10W40 Blue Streak Ignition Parts, Points Condensors, Rotars and Caps CHECK-UP TIME Blyth 523-9681 Brussels 887-9662 ASSOCIATE Radford Auto, Farm & Industrial Parts Ltd Mobile Service At No Extra Cost & Sun Roofs Vinyl Tops Locally owned & operated OURSERVICE WILLMAKE THEDIFFERENCE 190 Mitchell Ave. S LISTOWEL 291-1300 OVER 50 BRANCHES ACROSS CANADA
