If you hear chirp or squeal sounds when driving your car you can suspect that the engine belts are not working correctly. Faulty belts reduce engine transmission power, have steering and other problems. Most modern cars have just one or two belts. There are mainly 3 kinds of belts: fan belt, alternator belt and serpentine belt. The serpentine belt is a single continuous belt that drives accessories installed on the engine such as the alternator, power steering pump, water pump and air conditioner compressor. This belt is supported by an idler pulley or spring loaded tensioner to keep drivers from slipping. The timing belt is located outside the engine but is routed over multiple gears for engines with multiple camshafts. This belt is easy to manufacture and assemble as it does not require oil for lubrication. The normal replacement period is between 60,000 to 100,000 miles.
Engine cooling parts are often taken for granted. A vehicle’s cooling system prevents the engine from overheating by absorbing heat and transferring it to the air via the car radiator. Engine cooling parts include the auto radiator, water pump, coolant reservoir and coolant temperature sensor. Every vehicle has a recommended period for replacement of the coolant. Typically every radiator has a central core of fins and tubes, an inlet tank and an outlet tank. Most radiators have aluminium cores with plastic or aluminium tanks. The coolant flows from the engine through the core tubes where the fins absorb the heat and transfer it to the air. The most common problem in aluminium radiators is leakage due to a worn gasket or corrosion.
How do you fix or replace timing belts? The timing belt kit provides you with all the required accessories for replacement of a timing belt. It comes with belts, tensioners and idler pulleys. Timing belts help synchronise the movement of the engine’s valves and pistons. When this synchronisation breaks it can lead to larger issues of the engine related to pistons, cylinders etc. Make sure you check the timing belt at regular intervals to avoid such problems.
Is your vehicle getting overheated? Overheating of your car engine is dangerous for your car and indicates failure of the cooling system. Your car’s cooling system can fail due to failure of the radiator. It is useful to know how to fix a leaky radiator. Clogging of the cooling fins or leaks in a radiator can lead to overheating of the engine. Cooling system parts include radiators, fan clutches, water pumps, coolant recovery tanks, thermostats, radiator fan switches, motors, hoses and clamps. Oil also acts as a coolant and carries away some of the heat from the parts.
When replacing parts of the car engine never compromise on quality and the best brands. There are many popular brands and manufacturers of belts. Bosch, Dorman, Hayden, Delphi, Acdelco, Beck Arnley and Denso are some of the more widely known companies. Gates, Dayco and Gatorback are specifically known for their belts. Goodyear is known for serpentine belts.
There are several popular brands and manufacturers of coolants and cooling system parts. Some of the renowned brands are Bosch, Dorman, Hayden, Delphi, Acdelco, Beck Arnley and Denso are some of the more widely known companies. Exedy is known for clutches, Fel-pro is known for its gaskets, while Bosch and Carter are known for fuel pumps. Radiators are manufactured by Koyorad and Flex a lite.
How do we know whether a belt needs to be replaced? A screeching sound is often an indication that a belt is loose. The drive belt is made of sturdy rubber and degrades when it comes into contact with petroleum products or other chemicals. It gets damaged due to loss of engine cooling which quickly renders the vehicle unusable. Although the belt usually lasts up to 75,000 miles, replacement is recommended at the 45,000 mile mark.
The toothed, reinforced belt used to drive the camshaft via a sprocket to a crankshaft is known as the timing belt. This belt ensures synchronization of the engines camshaft, crankshaft and distributor. It also maintains accurate synchronization required to keep the engine’s valves and pistons moving in sync. Its hoses and steel lines transfer coolant, brake fluid and fuel throughout the vehicle. Over time, these parts may crack, rust or leak.
In general belts make less noise. They stretch and loosen and cause whining noise before breakage. This is an indicator of a failing belt and that it requires replacement. It is easier to replace a belt because it takes less time and less labour charges.
Many engines have a timing chain instead of a belt. A timing chain requires replacement after 150,000 miles. It has less chance of breakage or damage but will tend to start stretching. A severely stretched chain could jump teeth, will have timing issues and might damage engine valves. Replacing a worn out timing chain is expensive and time-consuming.
If either belt breaks, the vehicle will come to a halt. Once a timing belt breaks, the engine shuts off and you will not be able to restart it. Even if you are able to restart the engine after an accessory drive belt breaks you will not be able to get far if it does not drive the alternator. Without the alternator, you will end up relying on electrical power from the battery which will not last very long.
Aluminium is a light metal, a good conductor of electricity, non-corrosive, reliably strong compared to steel, withstands high temperatures and is easily available. Hence it is used for making vehicle parts such as wheels, bumpers, piston, piston-head, engine cylinder, radiators for cooling the engine, electrical parts and for body cover in some luxury cars.
All the heat energy produced by combustion in the engine is not translated into mechanical energy. Only 1/3 of total heat energy produced is converted into useful mechanical energy. The remaining heat energy is dissipated by the engine body and exhaust. The body of the engine has to be kept cool for the rotation of gears and wheels and for the functioning of other parts. This is done by using coolants, coolant additives, polymers, radiator, fan and exhaust.
The radiator is a heat exchanger used for cooling engines. It is connected to the engine with channels through which a liquid coolant, water or antifreeze is pumped. By taking the liquid through the engine, it heats up the liquid from the coolant tank and takes it outside the engine and allows it to cool down. The radiator is in front of the vehicles grill to allow airflow as the vehicle moves.
The radiator is connected to a fan which cools the engine. A shroud is fitted to the fan which forces the air through the fins to remove the heat. A thermostatic switch called fan-clutch attached to the fan engages and disengages the cooling fan saving power.
The coolant is a mixture of water and antifreeze in the engines cooling system. It takes away heat, lubricates the water pump and prevents the system from freezing in cold weather. Coolant additives are a mixture of polymers and water that protect engine components from corrosion and prevent formation of sludge and scale. The coolant additive can be directly poured into the radiator by using a funnel or through a filter. Coolant filters purify the coolant fluid in its course through the engine. They trap contaminants and prevent them from damaging the cooling system.
