As winter arrives, so do the messy roads and an importance of topping up on the right wiper fluid.
Automotive gurus warn leaving summer-rated fluid is not a good idea.
"Typically, the pump is at the bottom of the reservoir so you can damage the pump if the fluid freezes," explained Fort Saskatchewan Jiffy Lube owner, Jim Martin. "When it gets on your windshield, if it's not the proper strength, it can freeze causing visibility issues."
Martin recommended a fluid rated to at least -35 C, although fluid that is rated for colder temperatures is better suited for the snaps of extreme cold.
Leaving the remaining summer fluid in the tank may seem convenient and while in the mild, early days of winter it may be fine, later on it may be a good idea to flush the system.
"You can do that simply by running the existing fluid through the system and letting the wipers wipe it off."
Along with ensuring the spraying system is working correctly, it will also test the wipers to see if they're still adequate for winter. Any streaking means it's time for new wiper blades.
