I have always used premix coolant in other cars, comes in a 50/50 mix, just buy and pour! I would like to run 70% water to 30% coolant in the FD. How do you know how much of each that is? Basically how many jugs of coolant and the rest distilled water?

3rd gen coolant capacity is 9.2 quarts, you should run 2.76 quarts coolant to put you at 30%.

If you have the stock radiator....

go to any autoparts store and they sell a little tool that will tell you the percentage of water to coolant mixture...

Or get a nice clean bucket. Pour seven parts distilled water and 3 parts coolant into it. Then add it to the car. If you need more... repeat? https://www.nopistons.com/forums/pub...IR#>/smile.png

empty gallon jug works well, you can keep whats left for top offs and future coolant needs

fill the coolant system with watter and then drain it back out mesure how mutch u have and work from there

for some reason this post reminds of me Die Hard 3 where bruce willis and Samuel Jackson were trying to figure how to get 2 gallons in 4 gallon jug and a 1 gallon just or something like that... to get it weighed.

lol, cheers you hit that one on the head. I was thinking about how I hadn't seen that movie in awhile.

Depends on how worried you really are about it. If you really are concerned about getting it correct it will take the device mentioned to measure specific gravity of the coolant.



By parts will be hard to get accurate if you already have some coolant in the engine.
