What is a recommended coolant for the 2011 Toyota Camry?

The 2011 Toyota Camry isn't particularly picky when it comes to coolant; the main determination You'll want to make is searching the jug for the disclaimer that it's "Approved for use in Toyota Vehicles". It's also very important that You don't mix different coolant types; You can end up creating a chemical reaction that makes a substance akin to some jello. If You're unaware of what's in Your system, You can usually identify by color pretty well. If You're unsure though, You should drain and refill the system instead of just topping off. Mixing coolant in proportions greater than 10% of show has been shown to cause engine damage, so if You DO choose to just top off, ensure that Your coolant type is the same.
