A fully functional water pump is of absolute necessity for your car’s engine. It is responsible for keeping your car engine’s temperature in check. A water pump essentially does nothing more than move through the engine block, the hose, and the radiator. As long as it functions properly, your car’s engine should not be facing any problems regarding heat generation.
If you have noticed that your car has some heat related problems, you should get your water pump checked. If you do find that it is malfunctioning and you are in the need of a new one, here are some of the best water pumps for a 5.9 L cummin engine.
Best Water Pump for 5.9 Cummins
1. ACDelco 252-318 Professional Water Pump Kit
Our first choice here is a budget-friendly water pump that is perfectly compatible with a 5.9 L Cummins engine. The ACDELCO 252-318 is one of the very few affordable yet good quality water pumps out there which is why it makes it to the top of our list. Now there are various reasons for you to go ahead and purchase this pump as a replacement, the first reason being, this product would have almost a one-piece, no fuss product if it was not for the extra hardware like o rings, gaskets, seals, etc. which are needed for the installation.
All of the bearings are welded to the main component of the water pump which is also a big plus in terms of durability. Parts that are welded together collectively make for a strong frame. Coming back to the hardware required to install the water pump which includes o rings, gaskets, seals, etc, are all provided with the main pump which makes this an even better deal for the kind of money you are paying for this product.
The seals are coated for increased longevity. The water pump as a whole is OE certified which means it will fit right into your truck/car engine. OE stands for original equipment, so you can be sure that the product that you receive will be up to the standard mark.
The only slight downside to this product is the fact that the hardware that is su[pllied with the pump is not of the greatest quality. Most people switch it out for something better but that is just a personal preference. Even if you do plan on switching the hardware out, the one provided will help act as a base for you to find the right products. All in all, you are getting the absolute bang out of your buck when putting your money into this product and I would highly recommend it to anyone who is looking to trade up.
2. Gates 43034 Water Pump
This is another great alternative for people looking to upgrade their water pumps. It falls under the same price category as the previous one and does essentially whatever a water pump is supposed to do and that too quite efficiently. It is a cult favorite, to say the least, and that is why you will often see it move in and out of stock. A product that is a people’s choice can be quite reassuring. The fact that so many people are avidly investing in buying it is only indicative of its quality. A couple of things that work in its favor are the make and the hardware kit.
Unlike the last pump, the hardware kit on this one is of good quality and it also comes with an extra component which is only an additive but great nonetheless. The make of the pump is pretty solid with two strong metals, steel, and aluminum. This water pump too is OE certified and is 100% compatible with a 5.9 L Cummins engine. It is a great choice for someone who is on the lookout for one.
3. OAW CR3072 Engine Water Pump
This water pump is slightly more expensive than the ones listed above but does not seem to compromise a lot in terms of quality. It is just as effective as any other basic water pump that you can find in the market and that might seem a little unjust for the price. However, the maker takes the trophy in this case. It is not extravagantly good at what it does but it will last you a pretty long time while doing a decent job.
It is again OE certified, so you do not have to worry about it not sitting right in your car’s engine. It has carbon-ceramic seals which are pretty good for how reasonable the product is. The seal is strong and adds to the durability of the product. The seals are allegedly so good that they do not give way to leaks even after years of use (and quite honestly, abuse). Like any other water pump, it does come fully equipped with a hardware kit to go with it to facilitate easier and more convenient installations.
This water pump is not the most sought after and that has got a lot to do with the high price point. But if you have got the money to spare, there is no reason why you should not get your hands on this. It sure is an investment and it might end up saving you a whole replacement or many other adjacent problems in the future. Overall it is a pretty decent product and is worth a lot more attention than it attracts at the moment.
Reasons Why Your Water Pump Might Be Faulty
Coolant starts leaking
A car water pump consists of various compartments that carry coolant in them. If your car’s water pump is disorderly or broken, this coolant will start seeping through the crevices and gaps and eventually start leaking towards the front center of your car. When you see this happen, it should be a clear indication of a faulty/old water pump. This is not a symptom from the initial stage that can be repaired. At this point, the best thing you can do for your engine is to replace the water pump.
Unusual sounds coming from your engine
If you start hearing whining noises coming from your car’s engine, the water pump might be to blame. This whining sound is caused due to the loosening of the water pumps belt. This causes greater friction which in turn leads to the production of this high pitched sound. Time to switch the water pump.
Engine starts overheating
This is a telltale sign that the component of the engine that is malfunctioning is the water pump. Of course, greater pressure induced on the engine can also be the cause of engine overheating but for the most part, when you notice this happen, your first guess should be a malfunctioning water pump.
Radiator starts letting off steam
This symptom goes hand in hand with the previous one. As your stem starts to overheat because of a lack of coolant, the radiator does too. (Duh.) This sign, unlike every other one, should not be ignored and should be treated immediately. If you continue driving your car/truck with an overheated radiator, it might lead to the engine blasting or your entire engine eventually decaying.
While water pumps are not nearly as expensive as most other car modifications/additions, at the end of the day, it is money spent. And when you are spending a chunk of your hard-earned money behind improving your car/truck’s overall health, you must do it well. So to help you make the right decision and not end up with buyers remorse, listed above are some of the best water pumps that I could have my eyes on.
These are all A-list products that will not be disappointing you at the very least, if not wowing you with their impeccable functionality. Hopefully, all of this above-mentioned information helps you land on at least some product you love, if not one from the list. The main aim is to get the part most suited to you, your vehicle, your preferences, and your budget. Everything else is secondary.
