38 ~' Wednesday, October 26, 1988 - ‘North Shore News WINTER DRIVING THERE IS perhaps no greater in- convenience of winter driving than a heater that won’t work. Most passenger compartment heaters use the coolant to warm the incoming fresh air.

The thermostat acts as a heat- sensitive valve that regulates the flow of coolant to the radiator. When the thermostat fails or malfunctions, the engine either will overheat or take longer to get any heat because the engine will take longer to reach proper operating temperature. Flexible hoses convey the liquid coolant between the radiator and the engine. They should be inspected for softness, cracks and cuts. In nor- mal service, they are affected by air, heat, chemicals, oil and cons- tant vibration. These conditions either could harden or crack hoses, which destroys flexibility and causes leakage, or soften and swell the hoses, producing lining failure and hose rupture. Two other important hoses run parallel from the engine to the heater, normally found under the dashboard. These, too, should be checked for swelling and cracks, and for abrasion to the hose cover where the hoses come in contact with the engine block. The water pump/fan drive might be called the heart of the cooling system. Coolant circulates throughout the engine by means of the water pump, which is driven by a rubber belt. Loose or worn belts could mean failure of the drive. Check the condition of the drive belts by turning them over. Any that are cracked, frayed, brittle, wet with oil or highly polished on the sides that contact the pulleys should be replaced. Regardless of the visual condi- tion, belts that are more than four years old should be replaced, ex- perts advise. These troubleshooting pro- cedures could solve the problem of a malfunctioning heating system. Other trouble areas, such as a clogged or leaking heating core, faulty electrical connections and fuses, a broken blower motor or a non-operating heater control valve, should be checked as soon as possible. Slow warmup farms engine A FAMILIAR scene on a cool morning is a car idling in a driveway with exhaust billowing from its tailpipe. Ia the house, the owner comfor- tably finishes a second cup of cof- fee. The car will be toasty warm when the time comes to take off for work. The owner may justify this wasteful practice with the excuse that the car operates better when it’s allowed to warm up before driving. Wrong. When the choke is set, as is the case when a cold engine is started and then left at fast idle, the car is burning gas at a furious rate. Engine wear is accelerated because raw fuel from the enriched mixture washes lubricating oil down the cylinder walls. This also contaminates the oi] in the engine crankcase, further inviting engine damage. There is a greater tendency for spark plugs to foul under these conditions, too.
