Hello. Yes you can replace the water pump without replacing the serpentine belt. If the belt is worn, and it breaks while you are driving, you can damage a lot of other components in that area. Typically the price of a serpentine belt is relatively inexpensive. You will have to remove the belt to replace the water pump anyway. Since you are likely going to have to purchase a new pump, we do recommend that you purchase a belt at the same time. You SHOULD replace the belt if it is worn, and this is a perfect time to do it. It is not necessarily required, but you are putting yourself at risk of another break down at a later time. Not to mention if the belt is already worn, manipulating off and back onto the vehicle while changing the water pump can further damage it, and shorten the amount of time its got left. Belts should be replaced before they break, as to the amount of damage they can cause when they do break. Again, you may be able to get away with not replacing the belt right now, but if its as worn as you say, its going to break sooner than later and should be replaced.

If the serpentine belt breaks or even loses tension due to tensioner malfunction or even belt wear this can cause the water pump to not turn or pump the required volume of engine coolant which will in turn cause the engine to run hotter.
Should I replace the water pump with the timing belt? It is not necessary to replace both at the same time, however, it is highly recommended due to a high risk of engine damage. All parts of the synchronous drive have the same mileage and wear.
A drive belt is similar to the serpentine belt in that it performs those same functions. It operates the power steering pump, the water pump, the air pump, and your car`s air conditioning compressor.
There are a couple of factors influencing the answer to this question, but on average, your car should be able to run between 20-90 minutes with a broken serpentine belt. The engine will overheat faster without a functioning cooling system on a hot day, so your driving window is less.
The short answer is yes, your car will start even if the serpentine belt is broken or missing. To get the car going, the battery sends power to your starter motor. The starter motor provides enough power to get your engine moving and the combustion process started.
While the amount of the efficiency loss is small, it`s fair to say that replacing an older water pump can lead to a small increase in engine efficiency and fuel economy. A new water pump can also reduce engine noise. Again, older pumps likely have a bearing with some wear and tear.
No timing belt will give an increase in performance – it`s just not possible. Its main job is to keep the timing in check. Having your timing belt replaced and noticing an increase in performance is just a mix of the engine operating at peak efficiency and a good hit of placebo effect thrown in for good measure!
A serpentine belt (or drive belt) is a single, continuous belt used to drive multiple peripheral devices in an automotive engine, such as an alternator, power steering pump, water pump, air conditioning compressor, air pump, etc.
Of the parts that will eventually need to be replaced in your vehicle, the serpentine belt is one of the most important. How long does a serpentine belt last? Being made of durable rubber, a serpentine belt can last anywhere from around 50,000-100,000 miles.
Typically a damaged belt tensioner will not impact vehicle performance. It would cause the serpentine or drive belt to wear prematurely or to squeak – but not cause the acceleration issue.
It depends on what the belt runs. If it runs the water pump you won`t make it more than a few miles before overheating. If the water pump is still good you should be able to make it about 20 miles on a good battery.
Quick fact: If your serpentine belt is loose, you may have other mechanical problems like under-performing water pump, which can cause the engine to overheat.
Your car may frequently stall while driving if the serpentine belt isn`t doing its job. If the belt breaks as you`re driving, eventually the battery will die, and the belt could do other damage as it flops around under the hood.
The water pump is one of the vehicle components that may never require replacement if your vehicle is well-taken care of. You can own a car for over 15 years and never have to replace the water pump. That`s not to say that it can`t develop a problem.
When you have the timing belt replaced at a reputable service center, the service should also include a few other things. The tensioner and idler rollers should also be replaced. The technician will also inspect the crankshaft seal and the camshaft seal, replacing them if necessary.
Time is perhaps more important than miles. Seven years is the maximum life of the timing belt recommended by most manufacturers. For example, the belt should be replaced even if the engine has only 30,000 miles but is seven years of age. More timing belts break due to age than mileage.
Loosing the serpentine belt should not affect the engine timing.
There are three common V belt types: Classical V-belt (classified by their dimensions from A to E), Narrow V series (ranked by their sizes 3V, 5V, and 8V), and light-duty Fractional Horsepower belt (classified by their dimensions 2L, 3L, 4L, 5L). The letter X classifies their counterpart cogged belt.
Serpentine belts are much longer and wider than older V belts. Improved material quality lets belts last much longer. A narrow, deep V-belt design evolved into a wide, flat belt with teeth. Several V belts on older engines have been combined into one serpentine belt on newer engines.
Notched belts can use the same pulleys as cross-section standard V-belts. They run cooler, last longer, and are about 2% more efficient than standard V-belts. Synchronous belts (also called cogged, timing, positive-drive, or high-torque drive belts) are toothed and require the installation of mating grooved sprockets.
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.
The water pump moves the coolant through the system and the thermostat regulates this flow to maintain operating temperature. If the water pump has failed, the coolant will not flow through the system so the temperature will rise quickly and the heat will be concentrated on the engine.
Typically, serpentine belts last anywhere from 50,000 to 100,000 miles. Over time, friction and heat break them down.
