What are the 3 types of drive belt used in cooling system?
Belts & Hoses
- Timing Belt. The timing belt is a notched rubber belt that allows the crankshaft to turn the camshaft.
- Serpentine Belt. Serpentine belts, also known as drive belts, provide power to the air conditioning compressor, power steering pump, cooling fan, air injection pump, and more.
- Hoses.
When to replace the timing belt on a water pump?
When replacing a water pump run by a timing belt, always replace the timing belt at the same time, especially if the water pump was leaking. A coolant contaminated timing belt will have a reduced service life. On the other hand, a worn out timing belt may break and damage your new water pump.
Which is the best belt for alternator and fan?
So cars went from one belt driving the fan, water pump, and alternator, to 2 or 3 separate belts, now also driving the power steering pump, A/C compressor, and emissions air pump. The “V” belt is one of the most effective belt solutions because of its strength, relative quietness, power transfer, and durability.
How is the alternator belt connected to the engine?
It’s a variation of the V-belt (named for the Vs grooved into that give it traction on the pulley). It connects the water pump, radiator fan, air conditioning unit, and crosses the crank pulley. The alternator belt keeps the car battery charged while the engine is running, and is directly connected to the health of your battery.
What does the timing belt on a Honda do?
On some Honda engines, the timing belt also drives the water pump to circulate the engine’s coolant. Some engine models also have a second smaller timing belt that drives a balancer shaft system to cancel out engine vibrations.
When replacing a water pump run by a timing belt, always replace the timing belt at the same time, especially if the water pump was leaking. A coolant contaminated timing belt will have a reduced service life. On the other hand, a worn out timing belt may break and damage your new water pump.
When to change the AC and alternator belts?
replacing AC and alternator belt because they have to remove that for the timing belt anyway. The parts costs on the other belts is minimal but the labor to get to them is substantial (mostly the same labor as replacing the timing belt). So it makes a lot of sense to change all the belts at the same time and only pay for the labor once.
Is it normal to replace water pump and alternator at the same time?
It is normal to replace the water pump and other engine belts (alternator and compressor) at the same time. They should not charge you labor for replacing AC and alternator belt because they have to remove that for the timing belt anyway.
Where is the timing belt located on a car?
True, both are connected to the crankshaft. However, the former is located inside the engine, albeit by the outer wall. The latter is found externally, and drives many of the car’s accessories, like the alternator, power steering pump, and A/C pump. But, as NAPA explains, the timing belt sometimes pulls double-duty.
