The Cooling System
by: Kevin Schappell
The purpose of the engine's cooling system is to remove excess heat from the engine, to keep the engine operating at its most efficient temperature, and to get the engine up to the correct temperature as soon as possible after starting. Ideally, the cooling system keeps the engine running at its most efficient temperature no matter what the operating conditions are.
As fuel is burned in the engine, about one-third of the energy in the fuel is converted into power. Another third goes out the exhaust pipe unused, and the remaining third becomes heat energy.
A cooling system of some kind is necessary in any internal combustion engine. If no cooling system were provided, parts would melt from the heat of the burning fuel, and the pistons would expand so much they could not move in the cylinders (called "seize").
The cooling system of a water-cooled engine consists of: the engine's water jacket, a thermostat, a water pump, a radiator and radiator cap, a cooling fan (electric or belt-driven), hoses, the heater core, and usually an expansion (overflow) tank.
Fuel burning engines produce enormous amounts of heat; temperatures can reach up to 4,000 degrees F when the air-fuel mixture burns. However, normal operating temperature is about 2,000 degrees F. The cooling system removes about one-third of the heat produced in the combustion chamber.
The exhaust system takes away much of the heat, but parts of the engine, such as the cylinder walls, pistons, and cylinder head, absorb large amounts of the heat. If a part of the engine gets too hot, the oil film fails to protect it. This lack of lubrication can ruin the engine.
On the other hand, if an engine runs at too low a temperature, it is inefficient, the oil gets dirty (adding wear and subtracting horsepower), deposits form, and fuel mileage is poor-- not to mention exhaust emissions! For these reasons, the cooling system is designed to stay out of the action until the engine is warmed up.
There are two types of cooling systems; liquid cooling and air cooling. Most auto engines are cooled by the liquid type; air cooling is used more frequently for airplanes, motorcycles and lawnmowers.
Liquid cooled engines have passages for the liquid, or coolant, through the cylinder block and head. The coolant has to have indirect contact with such engine parts as the combustion chamber, the cylinder walls, and the valve seats and guides. Running through the passages in the engine heats the coolant (it absorbs the heat from the engine parts), and going through the radiator cools it. After getting "cool" again in the radiator, the coolant comes back through the engine. This business continues as long as the engine is running, with the coolant absorbing and removing the engine's heat, and the radiator cooling the coolant.
A cooling system pressure tester is used to check the pressure in the cooling system, which allows the mechanic to determine if the system has any slow leaks. The leak can then be found and fixed before it causes a major problem.
The above information is directly from the Auto Insight program which you can buy online from AutoEducation.com.
Common Problems:
Let's look at the common problems cars have with the cooling system.

· Broken hose. Hoses wear out and can leak. Once the coolant has left the system it can no longer cool the engine and it overheats.
· Broken fan belt. The water pump is driven by the engine through a belt. If the belt breaks the water pump can not turn and coolant will not be circulated through the engine. This will also lead to engine overheating.
· Faulty radiator cap. The radiator cap is designed to hold a certain pressure in the coolant system. Most caps hold 8 - 12 PSI. This pressure raises the point in which the coolant will boil and maintains a stable system. If your cap does not hold pressure, then the car could overheat on hot days since the system never becomes pressurized.
· Water pump failure. Most commonly you will hear a screeching noise and will be able to see coolant leaking from the front of the pump or under the car. Early signs are small spots of coolant under the car after being parked overnight and a strong coolant odor while driving.
· Head gasket... have large amounts of white smoke flowing out of your exhaust? Could be a head gasket. The head gasket seals the cylinder head to the engine block and also seals the coolant passages. When this gasket fails coolant can enter the cylinder and it will be turned to vapor as the engine fires. Head gaskets most often fail after the engine has experienced an overheating situation. When super hot, the cylinder head can warp and allow the gasket to fail.
Preventive Maintenance:

· Check all belts and hoses regularly. (at oil change is a good time)
· Look out for coolant leaks underneath the car, they could be signs of trouble to come.
· Change your coolant every 2 - 3 years depending on the manufactorers recommendations.
· Inspect your radiator cap for deterioration of the rubber seal. Replace if you think it is worn. $5 - $10 is cheap insurance.
· Have your coolant system flushed every 5 years. It gets all the corrosion which has built up out of the system.
What to discuss with your mechanic:

· Let your mechanic know when your overheating problems occur. Overheating when idling points to a different problem than overheating at highway speeds.
· Ask your mechanic if it's worth changing the timing belt or chain while he is replacing your water pump. Many times the timing belt turns the water pump so it has to be removed anyway to access the water pump.
WARNING: Never open your radiator when the engine is hot. The pressure in the system can cause hot coolant to splash out and burn you.

Tips For Winter Driving
 by: David Maillie

Winter driving can be hazardous and stressful. Wind, snow, ice and blizzard conditions increase the normal dangers of driving. There is a lot you can do before the winter driving season and during a storm to protect yourself and your family.

Before winter arrives, have your car inspected to be sure it is ready for the road conditions. You can do this yourself or take it to a qualified mechanic. Check the battery, wipers and fluid, thermostat, brakes, ignition system, antifreeze, exhaust system, lights, oil level, heater and defrosters. Make sure everything is in good working order to keep you safe throughout the cold weather.

Check your tires to be sure they are road ready. Install tires that are appropriate for the driving conditions. In moderate amounts of snow, all weather radials will do the job nicely. If you live in a climate where you experience a lot of snow, consider snow tires. These have better tread to deal with snow and ice.

Prepare an emergency kit to keep in the back of your car. This will ensure that you are prepared in the event that you get stuck in the snow. Things to include in the kit:

Ice scraper
Small broom
Small shovel
Kitty litter or a bag of sand (to give traction if you get stuck in snow or ice)
Blankets or a sleeping bag
Flashlight with batteries
Flares or warning triangles
Plastic bags
First aid kit
Tool kit
Jumper cables
Bright cloth to use as a flag
Help sign for back window
Extra hat and gloves
Food and water to sustain you if you get stuck
A book, Bible or Prayer Cards to keep you busy and calm in the event you get stuck.
Charged cell phone (always carry this, especially in the winter)

Keep your gas tank at least half full at all times. This adds weight to the car and will ensure that you won’t run out of gas in the event you get stuck.

Driving in the Snow

Pay attention to the weather forecasts and road conditions in the winter months. If the weather is bad, stay home if at all possible. If you must venture out, travel in the daylight. You are more likely to find help if you get stuck during the day. Never warm up your vehicle in the garage. This releases carbon monoxide, which is toxic and can kill you.

When driving, always wear your seatbelt. Wear sunglasses to protect your eyes from the glare of the sun reflecting off the snow. Know your car and how it handles in the snow. Features like traction control and antilock brakes can be useful in bad weather conditions. Know how these work and if your car is new, practice driving it in a snow covered parking lot before venturing out on the road.

Take it slow, especially in icy conditions. Don’t tailgate and be sure to allow a safe distance between vehicles. Do everything slowly, stopping, accelerating and turning. Leave plenty of time and space to maneuver. Sliding and skidding usually happen when turning, stopping or accelerating. Going extra slow will ensure your safety.

If the visibility is low, slow down even more. Consider getting off highways and driving even slower. This will take you out of the path of large trucks that can cause accidents. Use only your low beams, as your high beams will reflect back off the snow and won’t increase your visibility. Turn on your hazard lights to be sure other drivers see you.

In the event your car gets stuck, don’t get out. Put up the hood and tie your cloth to the antennae. This will make you more visible to emergency vehicles and other drivers. Keep the windows, air grill and tail pipe clear of snow. Wrap up in blankets and huddle up with passengers to stay warm. Run the heat for fifteen minutes each hour to keep from freezing. Move your body around to stay warm.

Keeping your car clean throughout the winter is important. Salt on the roads is important for safety, but will wreak havoc on the finish. If left on for long periods, it can cause rusting. Wash your vehicle weekly to remove salt and wax to protect the paint. Salt also leaves a coating on your headlights that can impair their operation. This will make you less visible to other vehicles. New Lite Headlight Cleaner and Restorer will return the lights to like new condition.
