Hey guys, I took my rb25 out of the car over a year ago, it's been sitting ever since. I started working on it, and realize there's a lot of corrosion and deposit left from the dried up coolant. What's the best way to flush it before putting it back in the car. Thanks

Machine shops hot tank for cheap?

I have been using a high pressure washer and carb cleaner on engines with great success. Try letting the carb cleaner soak in and then use a wire brush on it. Should work okay for blasting out the water passages too.
