How does engine pulley work?

There are two main types of car pulleys: crank pulleys, and accessory pulleys. Most pulleys are driven by a main crank pulley, which is bolted onto the crankshaft. When the engine is operating, the crank pulley rotates, transferring motion to the other pulleys by means of the serpentine belt or v belt.

Do I need to put RTV on water pump gasket?

Please note that RTV is not to be used on the entire gasket; the gasket should be installed clean and dry. RTV should only be used on the corners of the gasket and/or stepped casting areas that have a gap. Using a small amount of RTV will fill in those areas to assure a leak-free assembly.

Do you use Loctite on water pump bolts?

End of dialog window. I use high temp locktite to put the studs in the block, I use high tack sealant spray on the water pump gasket only on the pump side, and I use blue locktite for the rest of the hardware. All the bolts and threads have to be clean and dry for locktite to work properly.

Why is my water pump pulley not spinning?

In most cases, the water pump is binding up, causing the pulley to stop spinning. Replacement of the water pump will fix your problem. The pulley will need to be replaced if there is damage from the belt on it. If there is no damage, then the pulley can be reused.

What does a bigger water pump pulley do?

If you want the water pump to spin faster, you’d need a larger diameter pulley, not smaller. As I understand it, the reason for smaller balancer pulley is so that the accessories will spin slower, thus saving a few HP. So obviously the water pump will spin more slowly, and move less volume of water.

How much is a pulley replacement?

Idler Pulley Replacement Cost The cost to replace the idler pulley of your driver belt will usually be somewhere between $80 and $200. The cost for the new part should only be anywhere from $40 to $90, while the cost of the labor will be anywhere from $40 to $110.

What causes a pulley not to turn?

An accessory drive pulley can be misaligned in either of two ways: “parallel misalignment” (sometimes called “offset misalignment”), or “angular misalignment.” Parallel misalignment—the pulley is too far or not far enough onto its shaft, so that it is not in line with the other pulleys—is usually the result of …

Does the water pump spin freely?

The pump doesn’t have the same kind of bearings as, say, an alternator, and some resistance is normal. As long as the shaft doesn’t get hung up on anything and doesn’t feel gritty when you rotate it, it’s fine. Thanks Mark.

How do you know if you have a bad water pump pulley?

Common signs include physical damage to the water pump pulley, extensive wear on the water pump, grinding sounds, and the engine overheating.

How do you know if you got a bad pulley?

Should impeller spin freely?

It shouldn’t spin like a top but you should be able to rotate it 360 degrees smoothly with out it having any binding or sticky spots. It’s hard to describe the amount of force it should take to spin it but it shouldn’t be much.

Do pulleys increase horsepower?

Underdrive pulleys will yield a small increase in horsepower anywhere from 8 to 15 hp. This is accomplished by reducing the amount of power needed to drive the engine accessories that eat up precious horsepower.

What does a bad water pump pulley sound like?

Whining or Groaning Noise A whining or groaning noise usually means that either a drive belt is loose, or the water pump pulley is bad. It may surprise your customer that a pulley could fail, but it does occasionally happen. Pulleys have been known to fail due to rust, which can cause cracking between their bolt holes.

Can a bad water pump cause a clicking knocking noise in my engine?

An inadequate water supply will result in a lower flow being discharged from the pump and can create a loud knocking noise. Inspect the incoming line for obstructions; increase line size and/or increase supply line pressure. Pump inlet and discharge valves control the flow in and through the pump.
