driving it. The Toyota pink SLLC (super long life coolant) is supposed
to last 10 years or 100,000 miles, so I decided that it was time to
change it out.
We opted to do a simple radiator drain and refill which replaces about
half of the old coolant. This is more than enough preventative
maintenance to keep the cooling system working well when done every
I took pictures of the process and created a quick guide to help out
other Corolla owners.
Here's the guide -
The procedure should also be very similar for other Toyota vehicles
like the Camry, Matrix, Yaris, Venza, and Avalon.
I hope someone finds it to be useful.
Re: Toyota Corolla Coolant Change DIY Guide With Pictures
Pretty good job. Note that the Toyota cooling system is a "closed" system,
not open. An open system does not recover the coolant.
I also would not recommend a generic radiator cap as the cap is supposed to
open at a specified pressure. If it opens too soon, coolant boiling
temperature goes up, and if it opens too late, you risk damage to the
cooling system. Genuine Toyota radiator caps are very reliable and
long-lasting so I recommend the few extra dollars to get a genuine part.
