Coolant flush or drain & refill in a 2011 Camry?

Toyota calls for a drain and fill but, unlike the transmission service, a flush is ok (won’t harm anything) and is more effective at fully purging and exchanging the coolant. Whichever one you do I highly recommend you use the recommended Toyota coolant (typically red in color). The dealer will use this but so will many independent shops if you request it. Expect to pay a little more for it than the generic green stuff. The Toyota coolant is spec’d to give your water pump long life.
