I have just had to replace a water bypass pipe and now need to bleed the system as there will be some air in it

any ideas ?


many thanks phil

"there will be" or "there is"?

i've neve rhad any issues with honda's and bleeding the water system. just leave engine running till it's hot - thermostat will open and allow water to circulate properly, and should self-bleed.

ensure there is plenty of water in both the radiator itself, and enough water in the header tank to cover the end of the pipe thats part of the cap.

i did that but the heater failed to get hot, air in the system

i have looked for the heater bypass to help bleed it and i dont seem to have one hmmm

have you run the heater on max heat, max fan speed for a good fifteen minutes?

Really stupid question, but, is the heater valve operating? Never seen one needing the system bled yet. Try squeezing the top hose when the engine is hot and the rad cap off, or get a mate beside you, remove one of the heater hoses and his finger over the hole it leaves, then fill the hose/heater with water from a jug whilst holding the hose in the air, refit hose losing as little water as possible and run engine to check.Keep an eye on the water level in the header, if it goes downair is seeping out and the system primed.I hope.

It should self bleed after time, but there should be a bleed valve to speed up the process...

I had the same problem on my car when putting it back to the mechanical water pump. No heat in the heater and temp gauge would go to hot. Too much of an air bubble in the system to allow it to self bleed

2 methods easier method (the one I didn't do!) and harder (the one I did)

Easy: Jack up the front of the car as high as it can go to get the bubbles out.

Harder: Split the heater hose and use a big funnel

Had the same problem when I swapped my radiator
That is by far the easiet route!

BTW it won't self bleed, mine didn't after 500 miles and the workshop manual technique won't work either
