Timing Belt Information & Guide

Volvo Timing  Belt Replacement Cost – All Models


Engine and piston movement synchronized with the smooth and toothed rubber belt is known as timing belt. It use to synchronize cam and crank shafts, replaced the standard chain drives overhead camshafts were begin  into engine technology in 1970s.

From highly saturated nitride (HSN), a special high temperature grade of rubber timing belts was introduced by Gates. The first belt was made of polyurethane with steel cord tension members. After so many developments in technologies, polyurethane was changed by very strong and temperature-resistant rubber materials. Many companies includes Dayco started producing automobile timing belts.

The tension members replaced to fiber glass which provides very good flex and very low in lengthen.

Later then developments in engine supported by the style to transparency camshafts, synchronous belt drive system become more common in engines now a days and this style was also supported by many advantages of synchronous (toothed) belt drives as well as:

  • More easy drives
  • supple belt routing
  • lesser cost
  • Low lengthen behavior and friction losses
  • Constant timing over engine life
  • Lower fuel utilization
  • Less discharge

The crankshaft drives the camshaft(s) and actuates the valves using a belt or a chain. The timing belt is broadly used by car manufacturers because of its advantages over chain, namely reduced space, include lighter and quieter running.

Now a day, one out of every five passenger cars and light trucks use a timing belt to broadcast power from the crankshaft to the camshaft(s). There is difference in serpentine belt and timing belt. Do not Mix it.

Most 4-cylinder and V-6 engines, as well as a few V-8s, use a timing belt. The timing belt is serious to the engine because it sets the engine’s intake and exhaust valves in motion.

 The benefits of using a belt contain

  • Less Vibration
  • A chain drive system shows a lower transmission error.
  • A belt drive system can be optimized to be equal or better than chain.
  • Reduced Noise n Creep/Wear
  • Current belt technology provides less than 0.1 percent total length change.
  • Durability/Capability
  • A belt drive system uses less components and part numbers.

Timing Belt working in Car

Due to timing belt is made of rubber that keep camshaft and crankshaft to synchronize because of that the valve timing is always right. If the valve timing is off engine won’t run correctly. In fact it will not run at all. The belt or chain also regulates the power steering and water pump. It is tighten with tensioner in car engine.

In four stroke engine timing Belt works in four strokes are:

  • The intake stroke
  • The compression stroke
  • The combustion stroke
  • The exhaust stroke

Timing belt is replaced after every 60,000 to 90,000 miles or it has been checked otherwise it created problem and it should never be ignored

Timing Belt symptoms

If timing belt is worn out or broke. It creates following bad belt symptoms or may be having more. It is necessary to have a certified technician or mechanic check the timing belt and change it if it essential.

  1. Rough Idling of the Engine
  2. Misfire of the Engine
  3. Smoke from the Engine
  4. Oil Pressure Decline
  5. Pistons or Valves That Are Broken

Timing Belt cost for Cars

Replacement cost of a timing belt is dependent on the service were spent on the changing job. In some cars, It is harder to gain access the timing belt and for economy cars with small engines the service should be cheaper because it is easier to disassemble and replace to new one but in bigger engine like trucks engine it will be pay more due to bigger engine. It is easy to replace belt in normal cars like you use in daily life. You can simply do it in 30-60 minutes using this guide.
