![]() ![]() The pulley’s unstable condition can also cause the water pump’s impeller to become imbalanced, leading to complete failure. Over time the bearings of the water pump pulley can become loose. As a result, your water pump won’t be able to maintain sufficient coolant flow, likely leading to engine overheating. So you should be aware of the underlying causes of water pump failure to take appropriate preventive steps.Ī worn-out or broken seal will lead to coolant leakage or even contamination of the fluid. The water pump is vital to your vehicle’s operation. Now, knowing about bad water pump symptoms to watch out for leads us to one very important question. Continuing to drive with an overheated engine can damage it to the extent that you’ll have to replace it entirely, which can prove expensive. Further, a faulty radiator cap can result in loss of coolant.Īt this point, it’s best to pull over your car and call roadside assistance. In fact, the radiator cap is quite important for a properly operating cooling system. If you observe steam or white smoke coming out of your radiator, you are dealing with a failing water pump and an overheated engine. ![]() To avoid further engine overheating, you should visit a certified mechanic for a proper diagnosis of the situation. In the long run, it can even reduce your vehicle’s life expectancy. It’s because a faulty water pump won’t be able to circulate coolant through the engine block, resulting in an overheating engine.Īn overheated engine can cause widespread damage to the head gasket, cylinder head, and pistons. One of the most common symptoms of water pump failure is a noticeable rise in the temperature gauge on your car’s dashboard. This water pump issue can be fixed by belt tightening, belt replacement, or water pump replacement.Īny unusual sound coming from your car engine is one of the tell-tale signs of water pump failure, and you should get it checked by a professional mechanic. ![]() The loose belt is commonly caused by a water pump pulley that has become loose with age or when the water pump bearings are worn out.Ī constant coolant leakage can affect the bearings of your engine’s water pump, thereby generating a squealing noise when the cars engine is in motion. High-Pitched Engine NoisesĪ loose accessory belt will cause your vehicle to emit a high-pitched, whining noise that becomes more pronounced with acceleration. This calls for an immediate installment of a new water pump. On opening the hood of your vehicle, you’ll see rust stains or tiny rust holes on the pump. In case your car is experiencing this water pump problem, it’ll flash the check engine light. The rust can also form when you use an incompatible or polluted coolant or a defective pressure cap that allows air into the cooling system.Ī corroded water pump will be less efficient at pumping coolant through the engine, causing engine overheating and potentially car engine failure. Rusty Water PumpĬonstant coolant leakage can lead to rust formation on the water pump. Do this before taking your car for a long drive or an extended road trip. Owing to the coolant leak, you’ll notice a puddle of orange, green, pink, red, or blue liquid in front of your car towards the center.Ĭonsult a certified mechanic when you spot a low coolant level due to leakage and have the gasket and water pump seal replaced. However, over time the gasket may wear out or develop cracks causing the fluid to drip underneath your vehicle, reducing your coolant level. The water pump consists of multiple gaskets and seals to ensure the coolant is securely contained inside and flows from the radiator to the engine without leaking. One of the most obvious indicators of a damaged water pump is a puddle of coolant on the ground where your car is parked. ![]()
