an overheating car, coolant leakage, or deteriorated performance of your engine or heat-based systems like the cabin heater indicates some sort of problem. However, you need to recognize the signs of a bad thermostat or water pump.
They can go bad with time and are very easy to replace. To conclude, both the thermostat and the water pump are essential components for a vehicle cooling system as they maintain the coolant flow responsible for keeping your car’s temperature in check. Bad Thermostat Or Water Pump: Final Thoughts Water pumps usually work for a very long time, around 1000 miles, so this one-time investment would save you from a lot of trouble in the long run. However, it should also be replaced because that’s a better alternative. The water pump, on the other hand, is a little more expensive than the thermostat. It’s better to replace the part instead and get on with it.ĭoing so wouldn’t take up a lot of your time or money as thermostats are not that expensive. While it is a simple component, repairing it would consume a lot of time and may even cause some complications. The water pump will be fully operational if you feel a rush of coolant in the pressed hoseīad Thermostat Or Water Pump: Possible RepairsĪs stated before, it is more viable to replace the thermostat rather than repair it.Open the radiator cap carefully or you’ll burn your hand.Idle the car until it reaches the operational temperatures.Checking the Pressure in the HoseĪnother excellent method is to check the pressure inside the cooling system while it’s still in operation. This method will not tell you exactly if your water pump needs replacement or not as a clogged radiator will also give the same results. Check if the coolant is flowing in the radiator.Keep on revving the car until it reaches the operational temperature range for the engine.Open the hood and remove the radiator cap.Once you know for sure that your thermostat is working, follow these simple steps: The two ways that help you know for sure if your water pump is operational or not are: 1. In other words, you’ll be still at square 1 with little to no progress. If that’s not the case, you’ll know that there is something wrong but won’t be able to pinpoint it. So, how does a stuck thermostat or a non-operational water pump cause the coolant to leak?īoth come with a major prerequisite that you must be 100% sure that your thermostat is working perfectly. In most cases, both the thermostat and water pump are equally likely to be a culprit in case of a coolant leak. In both cases, the position of the leak might give you a slight idea of the problem, but it’s not a guarantee. The next sign that may indicate a stuck thermostat or a bad water pump is a coolant leak.
Some of them are a blown gasket, a clogged radiator, a bad radiator fan, or insufficient coolant levels, that might have happened because of leaks, which is a symptom as well. Other than the issues we are discussing, your engine may overheat due to a plethora of other reasons as well. This means that they are the first thing you should check if you see your engine overheating. An overheating engine is a giveaway sign that your vehicle’s cooling system is not working.There are several reasons why that happens, but the most common ones are a bad thermostat or water pump.
