Q.: Rav4 Coolant Flush And Fill


Recommended Posts

My gf's '02 Rav4 is at the 32K Km maintenance interval which requires a coolant flush and fill. First, it's only 1 year old so is a flush required? If it is, I've seen the Haynes method (remove the alternator, thermostat, replace the thermostat housing and flush); a Toyota tech. told me to pull one of the heater hoses and flush at the rad cap; and, in rec.autos.makers.toyota, I was told to drain the block and rad and top up with 50:50 red stuff:dH2O and not to worry about the flush.

Are there any other DIYer flush routines?

at just over 30K just drain and refill. on the bottom of the rad there is a spout with a white screw in cap. back it off until the coolant starts to drain out. once its done tighten it back up and fill with 50/50 through the rad cap.
