Anyone know if there is a tutorial DIY for the 2AR-FE on this 2G Scion to flush the radiator and replace associated parts such as thermostat?

 

Not really a DIY, but page 34 on this shows some details about the motor and where the thermostat is located: http://www.rav4world.com/pdf/2AR-FE.pdf

 

Well its been a few months and hardly anyone has pitched in except one person. You'd think there'd be more participation from existing owners other than myself that actually want to provide to the tC2 community instead of using tutorials from other Toyota vehicles on other websites.

 

This forum is dead af, but it's a coolant flush.. just open the reservoir, remove the drain plug and drain the coolant from the bottom of the radiator (it has a drain bolt) and then fill it back up.. There's not much to it. You can run distilled water thru the system to really flush it out, but unless you have a pump that's not the most fun thing to do. As long as there aren't a lot of sediments in the coolant you should be fine just draining and refilling.
