2002 Toyota tacoma xtracab prerunner 2.7L 3RZ-FE Engine Block Coolant Drain Location.

I been flushing my coolant. But I could only do the Radiator and Reservoir.

I was a little worried about flushing the system without getting all the nasty water out of the engine block mainly because whenever you mix the long life coolant from Toyota the mix wouldn't be 50/50. I think at least 50% of the coolant is still in the engine block, without flushing it you'd have a 70 water/30 coolant. Flushing the entire thing will make it a little closer to 50/50.

After many videos and many hours of stress I finally found the engine block draining plug. It took me a minute to find it but it is located between the coolant temperature switch and the oil filter. It's very easy to spot with a flash light looking right above and slightly to the right of the passenger side tire. You'll need a 10mm socket and a plastic hose to attach to the little drain pipe to drain the coolant in the proper container.


Good luck on your next coolant flush you guys.

 

Thank you for this. Would have been really helpful back when I was flushing my coolant like a mad man. Looking forward to playing with it next time I want to clean her out.

 

It's on the passenger side of the engine block, you can access it through the wheel well. It has a little spigot with a 10mm bolt you loosen up.

 

Thanks! This post really helped me.
