Regardless of what time of year it is, you do not want to be the car on the side of the road that has overheated!
Your car’s water pump will last longer if you get your antifreeze flushed every 30,000 miles (or however often your manufacturer’s owner’s manual recommends). That way, the old antifreeze won’t become acidic and damage your car’s engine and important parts, including rubber hoses or the bearing in the water pump.
The primary role that coolant plays in your vehicle’s functioning is keeping your engine temperatures low. If you find that your temperature gauge is always high and your engine is frequently overheating, chances are that you need a coolant flush. And if you see bright-colored liquid lying on the ground or your garage floor after you are parked – let’s see if you have a leak in your system.
This is one of the easier things to maintain on your car, so don’t let it turn into a problem!
