I have a 92 civc cx hatch and I dropped in a JDM B16a1, so how much coolant am I gonna have to mix up for a B16 and stock civic radiator???

 

I'm pretty sure the rad's are the same size for both engines.

 

theres not a precise way to measure your coolant capacity because you have a swap, or else you could've just looked in your owners manual.

theres ways of doing this without having to make a thread about it... just keep mixing and adding by the rad cap and then start the engine, let the engine warm-up and let the coolant circulate to let all the air out and then top it off.

you know I didnt even realize the question until I read your post good save mizzo!!

 

The EM1 takes 4.8 qts, so it will be about that. Just have a couple gallons (at least one and a half) on hand, it's kinda hard not to spill some.

 

use a funnel just like the one you need for the oil. then you shouldnt spill any. a job for every tool and a tool for every job. i know i try not to spill fluidis in my garage.
