Heading to track.
Want to switch to pure distilled water and Motul MoCool.
What is the easiest, e-a-s-i-e-s-t way to drain as much of the coolant system as possible?
Does the radiator have a good old fashioned drain petcock?
If it does can you actually reach it and turn it?
Can you loosen a clamp and yank a lower hose off?
Thanks

I don't feel like breaking out the QuickJacks, getting the car up, pulling the pan only to find out it is some kind of Honda factory "sealed system" or something...

It's a pain. I only drained theough the radiator and there was a lot left in the system. I didn't check if the engine has a drain bolt. Apparently there's no cap on the radiator or if there is its under the plastic. Its hard to fill through the tank but since it has a pressure cap I think thats where you're supposed to fill it on this car.

There is a drain petcock bottom center of radiator.
Just a thumb twist to open.
Even a drain hole under it!
Prepared for a mess and didn't have one.
Specs shows 1.25 gallons of coolant and I got out very, very close to that.

Oh and it is 6.4 ounces of Motul MoCool to the 1+ gallon of distilled water.
From what I see/read this often results in engine temps dropping 10+ degrees.
Sure beats $5000.00 and taking half your car apart... only to find it didn't change a thing...
All in it's $21.50
