The part that you can be observant about is leaking coolant. The signs of a worn out bearing is either leaking coolant or an unusual noise, which is the result of the bearing losing its way. A wet engine or a coolant sob through your car’s vent are also signs that your water pump may be going bad.
If you notice any of these signs, it is necessary to get your water pump replaced. You will know if your water pump is functioning properly aside from these signs as well, because it is either working or it is not. What you may want to consider, though, is replacing your water pump when surrounding systems have to be replaced. The reason for this is because often times surrounding systems have to be removed just to get to the water pump, which can certainly be a hassle.
Another time you may go about replacing your car’s water pump is when the cooling system is due for a major service, such as a radiator replacement or removal. This is ideal because the first step in replacing the water pump is draining the coolant. It makes life a lot easier if the radiator is removed for added working convenience.
So the next time you are cruising down the street on a hot summer day and you are not getting any cold air, make sure to check the water pump. Being observant and paying attention to any unusual noises coming from the car’s vents and looking for a wet engine can be great ways to identify if you have a leaking coolant. If this is the case, it’s time to take in your car’s water pump and get it replaced.
