How Often Should You Flush or Replace Your Coolant & Transmission Fluid?
As a general rule of thumb, most Toyota models are recommended to have their coolant flushed every 50,000 to 100,000 kilometers, depending on factors such as type of coolant used. When it comes to transmission fluid flushes, Toyota engineers recommend that these be performed every 80,000 to 160,000 kilometers. It must be noted, however, that these intervals are approximate figures and are subject to change depending on your driving habits. For example, if you do a lot of towing, frequently drive in stop-and-go traffic, or operate your vehicle in extreme temperatures like that of Timmins, Ontario, you may need to flush or replace your coolant and transmission fluid more often. For the most accurate information, your best bet is to consult your vehicle’s owner’s manual.
