I did this and I think I was successful. The heat was blowing warm air, but not "hot". Does the heater only get hot while the car is driven? Or should I repeat the bleeding process a few more times?

only use honda rad fluid. its premixed. there are some other things to do, like open the block bolt and the air escape plugs as well. its in the service manual for the S and isn't difficult.


good luck

When I was bleeding mine, I couldn't get all the air out until I drove around the block a little after the car warmed up in the garage. Air would only get warm, not HOT, until I did this. When I got back I shut it off, opened the bleeder and got most of the last air bubbles out. After that, the heat was HOTTTT and the car was good to go after that.

I bought this and it was worth the money. Turn the heater temperature to the hottest setting, fan to the lowest, and watch air bubbles come out. You can rev the engine once in a while if you like.
I have one of those too. The Honda fitting works very well. I don't like the Nissan fitting as much, but it works.

Sorry for bringing back up an old thread from the dead but I folllowed the squeeze method Billman said on page 2 and as soon as bleeder valve is cracked open started getting fluid out immediately and squeezed the hose just to be safe and still nothing and I have done other previous methods that Ive searched around the site through google, even one that billman said to get a turkey baster and put it on the rear bleeder valve til fluid gets to the tip, even raised the front of the car til the radiator cap is over the rear bleeder valve, nothing works.....i havent had the heater working in the car since ive owned it and havent really cared for the last 4 years til just now even though i live in miami, fl and dont really need it most of the year but there are those horrible cold fronts that make me wish for the heater to work like this morning for me was about 42 degrees

I would not flush it with water. This system is one of the best designed and remains completely spotless.
Is this true even when switching from Type1 to Type2? He has a 2002, and may still have original coolant.


edit: realized this was an old post and he is long done with the procedure.

Just used the Billman method for my coolant change- simple and worked for me. I did find however as others have found that I had to rev the engine to assist the process and get the air out.

Added a bit of info to my original bleed. If you can add any tips to it I'll add them in.
