Some automotive issues make themselves known instantly and in a big way. But signs of a bad water pump aren’t always so brash. A bad water pump can wreak havoc on your engine and should not be taken lightly. But how does a water pump go bad? Here’s a few bad water pump symptoms that can help you deduce if repairs are in order.
Leaking Coolant
One of the most common symptoms of a bad water pump is a link hidden, please login to view from the water pump itself. Many water pumps are constructed with a weep hole below the pump drive shaft. Normally this weep hole is dry as the pump drive shaft seals keep the coolant at bay and away from the water pump bearings. But if the seal fails coolant can then seep past harming the water pump bearings and dripping out of the weep hole. The driver may notice a sweet smell of coolant cooking off the hot engine or a small puddle of coolant under the vehicle when parked. If the coolant is dripping on the accessory drive belt system there may be damp areas under the hood. If your vehicle develops a coolant leak or you find yourself adding coolant to keep it filled, check the area around the water pump just in case.
Overheating
One of the common signs of bad water pump functionality is link hidden, please login to view. The pump may not leak coolant, but the pump mechanism itself may have failed. Over time the fins of the pump can actually wear down to the point where they are no longer moving coolant. Cavitation can eat away at the metal pump vanes and pump surfaces. Plastic water pump vanes can disintegrate over time as the plastic ages. This all adds up to coolant that is no longer moved through the engine block and into the radiator to be cooled, leading to overheating.
Bad Noises
Water pumps have bearings that have to stand up to not only engine heat but also tension from the drive pulley. If you start to hear a grinding noise or high pitch squealing from the front of the engine, the water pump may be trying to tell you something. Try and rule out squealing belts by double checking belt condition and belt tension. Once you are sure the belt isn’t the cause try to pinpoint the source of the bad water pump noise. Be careful to not place any body parts near that rotating accessory drive system or the engine cooling fan. Simply stand in front of the running engine with the hood open and observe for a few minutes.
Oil Contamination
How to tell if water pump is bad can sometimes depend on the design of the engine. Some water pumps are buried inside the engine which makes it difficult to observe any problems. For example Ford Duratec V6 engines have the water pump located behind the timing cover. A leak from the water pump will allow coolant to mix with oil around the timing chains but the leak will not be visible on the outside of the engine. Checking the engine oil regularly and looking for an increase in oil level (due to coolant collecting in the oil pan) or a milkshake-like oil appearance are signs of possible symptoms of a bad water pump. Unfortunately these can also be signs of a bad cylinder head gasket, so further investigation will be required.
Any of these symptoms should be taken seriously and further investigation as to the source of the problem. If a bad water pump is diagnosed, it should be link hidden, please login to view. Don’t risk ruining an engine by putting off a repair that is relatively minor.

Delphi Technologies, a brand of BorgWarner, unveiled its new Sparta fuel-pump line at AAPEX, showcasing the latest offering in its expanded aftermarket portfolio.
Designed specifically for older and high-mileage vehicles, Sparta made its AAPEX debut with updated visuals and new packaging. The Sparta brand offers another revenue opportunity for distributors and customers, targeting a specific subgroup of older vehicles.
The company also demonstrated its fuel-tank cleaning tool live at the booth. The tool is designed for scenarios when the fuel tank is difficult to drop or full of fuel; the magnetic head is effective at collecting debris from hard-to-reach areas of the tank. The cleaning tool has been well-received by technicians for helping optimize their productivity and deliver customer satisfaction.
link hidden, please login to view Visitors learned more about other aftermarket product lines, including steering and suspension and engine management. Since the initial launch of the steering and suspension program in 2017,
BorgWarner has added more than 5,000 Delphi-branded SKUs, or over 150% growth to the product line now totaling 8,500 SKUs, including more than 2,000 control arms.
All chassis product offerings undergo thorough dimensional and material analyses including extreme temperature, fatigue, three-axis and salt-spray testing in order to ensure premium product, durability, quality and the perfect fit. Further expansion is planned across products such as tie rods, sway bar links, control arms, and ball joints, where the company currently has 98% sales coverage across both domestic and import applications. Similarly, BorgWarner has continued to expand its Delphi Technologies engine-management line by 175 SKUs over the last year, with engine-sensor coverage and ignition coils.
Exhaust-gas temperature sensors, a newer part added to the Delphi Technologies portfolio, now has nearly 50 part numbers spanning both domestic and import applications.
Delphi Academy
Booth visitors also learned about the Delphi Academy, which has been designed with input from technicians to ensure it caters to their needs. It has more than 30 courses run by ASE-certified technicians, with both hands-on and virtual options available on the platform. Technicians who lead those training courses were at AAPEX, offering the chance for visitors to learn from the experts. Several courses for electric vehicles and battery electric vehicles are already available through the Delphi Academy with updates planned in the future.
For commercial-vehicle distributors and technicians, BorgWarner brought the recently launched Cummins HPI Application Kit for the Hartridge HK1400 Cambox. The HK1400 is an all-makes solution for testing electronic unit injectors and electronic unit pumps and is an essential choice for diesel workshops servicing diesel commercial vehicles. The HPI Application Kit is a set of dedicated ancillary hardware that replicates real-world conditions for accurate HPI testing.
Additionally, the Hartridge Sabre CRi Expert was displayed at the show. This advanced, compact, all-makes common rail injector tester comes with new test plans, new test steps, injector coding feature and a 2,700-bar rail pressure range enabling testing of LD, MD and HD common rail applications. Its features and functions make the Sabre CRi Expert a future-ready testing solution that helps shops stay ahead of the market, according to the company.
