TYPE 2 COOLANT New and Improved

Correct me if I am wrong, u can drain one gallon of coolant from the radiator at a time. Becuase, the other gallon or so is still in the engine block, h2o pump...etc. My mechanic told me I can drain the radiator this week and drain that again next week or so.

There are 2 different procedures. You can drain and refill the radiator and only get out maybe a gallon or you can do a complete flush and then you will need 8.7 liters /2.3 US gallons.

or you can do the drain and fill with clean water for about three times, then drain and add the non-pre-mixed Honda coolant, one gallon. You'll end up with approx 50 50 mix.

As well, the repeated drainings, with the engine running in between, will flush out almost all the old coolant.

And then, you can do it Hotstartup's way....
