by looking at it.. there's no set line or anything really.. you just gotta guess. It's not a big deal if your overflow tank isn't full

If you didn't drain the coolent in your engine block, there is no need to bleed. If you did, what you do is fill the rad, put the cap on but not tighten. Rather, let it close half way, put your climate control all the way to hot, then start your car. The half-closed cap will let air steam out and you can stop after the radiator fan go on TWICE. Then tighten the cap, fill to the proper line and you are done.

As for radiator fan turn-on time, Mike and I did a test. For regular single core 1/2 size rad, it takes about 12 to 14 minutes for the fan to go on from a cold start. For a full size (GSR, ITR) rad, it takes about 1/2 hour.

If you have a 1.3 bar radiator cap, perhaps that will increase boiling point and make your ran go on later, or if you run full 100% distilled water?

Charles, your like a master at this now eh

I replaced mine last week, and its e to the z. (Once you figure out the stupid things you did). Remember to reconnect the fan. Thats the main reason it could not start, unless you broke the fan itself. But like others said, it takes a while for the fan to get going.

Glad to see a couple people using my 2 year old DIY

FYI: For those who are replacing a radiator who have an automatic, the lower connectors to the automatic transmission oil hoses can be unscrewed, so you can source out a manual transmission radiator and put it in your automatic transmission civic. The screws are on pretty tight and probably rusted a bit from all the salt/elements so get yourself some WD40 and some elbow grease and you will be good.

what i do wen i drain it out the block also like motor swaps and all that crap

there is a funnel u can buy its prety cheep it has a conection that wil fit onto the top of the rad and close like its a cap then the funel wil sit in there all buy itself and all i do is fill the rad up until there is 2inces in the fullel like its over full and start the car let it run rev it up every now and then u wil see air bubbles comeing up the funnel do this until the rad turns on and then whatever is left in the funnel i just throw it in the rez


il find out were i got that funnel from its a wicked tool it has a plug so u can just stop the flow if u need 2
