I was just wondering because my idle goes up n dn for about 30 seconds before it idles rt and someone told me to bleed the coolant and I was wondering how. I didnt know u had to bleed coolant

Civicse

fill rad with coolant
turn car on with the cap off until the fan turns on
fill more coolant if needed
wait until no more air bubbles come out
also might help to squeeze on the rad hoses to get some of the air out

lots of info if you search

or you could use the actual bleed-valve thing. Look on the flange where the upper radiator hose connects to the head....there's a little nipple/valve thing....turn car on, open the valve (10mm I think) until no more air bubbles come out.....close valve.....make sure and keep coolant full......viola

could be....could also be a leak somewhere. the idle on hondas tend to flux. a little bit w/ coolant thing.....bleed it then see how it does

Not all motors have the bleed bolt, my JDM B18C doesn't, ******* bummer it is. I'm going to replace the hose adapter for the upper hose to be able to use the bold. I'm tired of bleeding by watching for bubbles with the cap off.

Make sure you have the climate control set to full hot and leave it on full blast.
