Fluid is only drawn from the overflow tank as the engine is cooling and the volume of pressurized coolant in the radiator, hoses, and engine is contracting. It circulates through the engine block and absorbs heat from the engine, then takes that heat away when it passes through the radiator.Ĭoolant also contains additives that help protect against corrosion and cavitation (the formation of bubbles in the liquid). If you want, normally the overflow bottle is either a slide-in fit or retained by one bolt. Some also contain colorants, fragrance, and other additives.Ĭoolant, on the other hand, is a liquid used in engines to keep them from overheating. The chemical part of the mixture usually includes alcohols and surfactants, which help to break up dirt and grime so that it can be wiped away easily. Windshield washer fluid is a mixture of water and chemicals that helps to clean your windshield when you spray it on. No, windshield washer fluid and coolant are not the same. Is Windshield Washer Fluid the Same As Coolant?
I PUT WINDSHIELD FLUID IN COOLANT HOW TO
If you’re unsure of how to do any of these steps, or if you think there may be further damage to your car, it’s best to take it to a mechanic or dealership for service. Finally, refill the system with fresh coolant and check for leaks. Then, flush the cooling system with clean water to remove any residual washer fluid. Here’s what you need to do to fix the problem and get your car back on the road.įirst, check the level of your coolant and add more if necessary.

If you’ve accidentally put windshield washer fluid in your car’s coolant, don’t panic. Whenever the low washer fluid symbol appears on your dashboard, add more washer fluid. Replace the reservoir cap and wipe up any spilled wiper fluid. Use a funnel to pour fluid into the reservoir. Your engine will thank you! What Do I Do If I Put Windshield Washer Fluid in the Coolant? Find the washer fluid reservoir next to the engine bay and unscrew the cap. So, next time you’re at the auto parts store, pick up a bottle of Rain-X and add it to your coolant reservoir.

It’s an easy way to help prolong the life of your engine and avoid costly repairs down the road. But did you know that you can also use Rain-X in your car’s coolant reservoir?Īdding a few drops of Rain-X to your coolant can help keep your engine running cooler by reducing the amount of water that evaporates from the reservoir. If you’ve ever used Rain-X on your car’s windshield, you know how well it works to repel water. It could save you a lot of money and headaches down the road. So, next time you’re topping off your fluids, make sure you know which one goes where. In fact, it could actually damage your engine if you use it as coolant. The washer fluid is designed to clean your windshield, but it won’t do anything for your engine.

But what happens if you put the wrong fluid in?įor example, putting windshield washer fluid in coolant is a big no-no. You just top it off when it’s low and go about your business. If you’re like most people, you probably don’t think twice about what kind of fluid goes into your car. It is important to remove the windshield washer fluid from the coolant as soon as possible. The windshield washer fluid can cause corrosion and clog the radiator. Like the others said, the jug that you poured the washer fluid into is probably just an overflow (unless it has a pressure cap on the jug) so if you havn't run the car much since the mistake chances are your coolant is not very contaminated.įor future reference (and for anyone else who has made this mistake or might make this mistake sometime), if you had not run the car at all you could have simply removed the jug, rinsed it out, and refilled it with antifreeze and you would have not had any problem whatsoever.If you put windshield washer fluid in coolant, it will not mix and will float on top of the coolant. I think if you remove the thermostat and the lower radiator hose and a heater hose and flush out the radiator, the engine, and the heater core as I previously described and you should be fine. The other issue is that the washer fluid will probably break down your antifreeze over time so that you do not have adequate freeze/boil protection. Wherever there is an air pocket that area of metal will not cool properly and theoretically COULD cause a head or intake or something to crack. I think the main issue with the washer fluid in the coolant is that it will cause foaming wich can lead to air bubbles trapped in the cooling system. Even this method, though, will not sufficiently flush the block.there should be a plug on each side of the block wich would allow you to drain the engine completely if you wanted to make sure you got ALL the washer fluid out. The closest you can come to COMPLETELY flushing the system out is to remove the thermostat, the lower radiator hose, and one of the heater hoses and run water through the radiator, engine, and heater core until clear it comes from all three places.
