Most passenger compartment heat- ers use the coolant to warm the in- coming fresh air. In addition to pro- viding driver and passenger comfort, the warm air directed to the inside of the windshield generally prevents fogging or icing which obscures vi- sion. The personal distress of cold fin- gers and toes can be avoided, by in- specting the heat producing cooling system components in your car. The heater and its system of hoses arc very much an integral part of your car's cooling system. The heat- er, in fact, is like a small radiator and functions in much the same way. Here's how. Hot coolant is piped from the engine through the heater control valve and into the heater core, located under the dash in most cars. The coolant passes through the core's finned tubes and releases its heat. -A small electric fan forces air past the finned tubes and directs the warmed air into the passenger com- partment. The coolant is then piped ant loss due to boiling. The cap should be replaced if the seal of gasket is damaged, or if the spring is broken. The radiator filler neck also should be inspected for nicks or cuts which could allow pressure 10 escape.. How thermostat works The thermostat acts as a heat sen- sitive valve which regulates the flow of coolant to the radiator. When the engine is cold, the ther- mostat is closed and the coolant re - circulates back into the engine to pick up more heat until it reaches a predetermined temperature. back into the cooling system at the water pump. Begin with coolant Troubleshooting should begin with the coolant level (it should be visible just below the filler neck) and mixture (50 percent each of wa- ter and anti -freeze is recommended). A low level will reduce or cancel the flow of coolant to the heater, thereby reducing or preventing any heat output. The radiator pressure cap helps to raise and control the temperature of the coolant in the system; and pro- vides a limited reserve against cool- Essential ool- Essentisl to knowour batt�ry,y be careful with Iump-startiflg The automobile battery need not Several precautionary measures be a source of anxiety.

Cheek. belts on car pooling system Almost half of all motorists have never replaced the cooling system V -belts on their cars. Of those who have, the majority did so when the belts were at or near failure, which is normally in about five years. Based on these national survey re- sults, and the fact that belt failure goes up sharply as the car approach- es its fifth year, it is recommended that belts on four-year-old cars be replaced. First, the dramatic decline in the number of full-service gas stations has resulted in fewer mechanics to advise car owners when to change their belts. Second, there has been a signifi- cant change in the construction of modern automotive V -belts. Because of fewer full service. gas stations and the increase of gas -only Rotate tires at 6,000 miles To optimize tire mileage on front - wheel -drive vehicles, it may be ne- cessary to rotate tircs before the generally recommended 6,000 mile initial rotation time. In fact, the engineers say that all - season, mud and snow -type tires used on front wheel positions of any automobile or light truck may develop irregular wear at early mile- age due to the side slip that occurs during steering. This is especially true on front - wheel -drive vehiclesi,because of the heavier load and its effect on the stopping and steering torques. The best rotation pattern for radial tires is front to rear and rear to front, keeping the tires on the same side of the vehicle. _ outlets, under -the -hood maintenance is being neglected. The company es- timates that fewer than one in four car owners is changing his belts on a routine preventive maintenance basis. In the majority of cases, the major reason for replacement is be- cause the belt is at or near failure. To avoid inconvenience on the highway or costly towing and repair charges, the company feels car own- ers must adopt new maintenance habits and change V -belts before they fail. The second reason for recommend- ing regular replacement - modern bandless belt construction has re- moved the traditional wear indica- tor. When belts were made with the "banded" construction, they had a fabric cover, however, so they don't readily show the effects of higher r.p.m. engines, smaller and hotter engine compartments, and natural deterioration. Most car owners, and even profes- sional mechanics, may not be able to predict belt failure by appearance alone. Very often the belt appears to be in good shape just before it breaks. Properly inflated tires essential Your tires are designed to ride saf- er and wear longer when properly inflated with the correct amount of air. Properly inflated tires also help you car deliver better gas mileage because when your tires are properly inflated, they create less "drag". Do yourself and your tires a favor. Check your air pressure today - and then get in the habit at least once a month.

Connect positive (plus) booster cable to positive post of dead bat- tery. (The positive post is wired to the starter or solenoid.) 2. Connect other end of same cable to same marked post (positive) of booster battery. 3. Connect second booster cable (negative) to other post of booster battery. 4. Make final booster cable con- nection on engine block of stalled vehicle away from battery. 5. Start The booster vehicle and let it run for a few minutes. 6. Start the disabled vehicle, then remove cables in reverse order of connection. Further safety precautions should be followed when working on or in the vicinity of the automotive. *Whenever you work near a bat- tery, protect your eyes with safety goggles. *Never light a match or smoke when working under the hood of a car. *Be careful that metallic objects such as tools do not fall on battery terminals. This could cause sparks, leading to a battery explosion. *Never lean over the battery during the charging, testing or jump- starting. Steps for jump-starting the auto- mobile battery and tips for ensuring optimum service, safety concerns and precautions, understanding how the battery operates, battery service and useful terminology arc included in "Take charge = Know Your Bat- tery," a safety guide produced by the Battery Council International (BCI), 11, 1987 Page I IA inc.nvenience When the thermostat fails or mal- produces lining failure and hose functions, the engine will either rupture. A small leak not only overheat or it will take longer to wastes valuable coolant, but it also get any heat because the engine will reduces pressure in the entire sys- take longer to rcach proper operat- tem. ing temperature. If the thermostat is functioning properly, you should be able to feel the surge of warm coolant passing through the upper radiator hose. It is a good practice to replace a ther- mostat that is in doubt. Flexible hoses convey the coolant between the radiator and the engine. They should be inspected for soft- ness, cracks, and cuts. In normal service, they are affected by air, heat, chemical, oil and constant vi- bration. These conditions could either hard- en or crack hoses, which destroys flexibility and causes leakage; or soften and swell the hoses, which Two other important hoses arc connected to the inlet and outlet tubes of the heater. These, too, should be checked for swelling and cracks, and abrasion to the hose cover where the hoses come in con- tact with the engine block. Kinked hoses will obviously restrict the flow of coolant. Check the heater hoses to make sure the hot coolant is flowing through the heater core. The supply. line to the heater should be hot; the return hose should be warm. If the hoses are cool, circulation is not ad- equate dequate due to clogged heater core of = possible ice blockage in the core unit.
