So I just finished changing from a b16a2 head to a b16 sir ii head and was going to bleed the coolant and this kinda got me confused. The new sir ii has the bleeder valve and the old one came with a hose that goes into my intake. Which one Do I use ?????

NEW


OLD (is on the car right now)

Anyone want to help me out here?

Looks like the bleeder and the hose are in different locations. Just keep the old one. You don't need the bleeder valve to properly bleed the system anyways.

So then Do I just take the nut from the block out and put it back in when the fluid starts to come out? or do i just fill it with more and let the rest go into the reservoir?

What? If you need to bleed it you do it just like you would a D-series.

I was about to replace my radiator and hoses till I noticed I too do not have a bleeder where it is suppose to be. Someone said do it like a D-series but I have only had H-series and this is my first B-series and well I don't see why it doesn't have a bleeder. Would like any type of help. How would I make sure there is no air bubbles without having to use a bleeder when I don't have one.

obd2 b series didn't come with the bleeder on it. bleed the system with the radiator cap off.

Thanks guys. Was a little afraid to do it the really old school style, like I used to do on my 84 datsun 510 pu. Did it, works well, no problems, runs 5-10 F cooler than normal.
