i know you wern't having a dig alan, i understand your question now.dandywarhol wrote:It wasn't meant to be a contentious post Ady, I was just curious as to why the see-saw was required. I presume it's to create a little pressure during the downward "stroke" to purge any trapped air out. My thoughts are that the combination of pump pressure and the stat opening will create more coolant movement in the system than see-sawing and as air is lighter than coolant it will automatically rise to the highest point - i.e. the bleeder pipe.
As you and Hayden say, whatever suits the individual.
I also thought if I was a newcomer about to buy a Bongo and researched the 'net, I'd be put off by the well intended videos.
with ref to the lifting/dropping of the funnel in the vid, kirsty would im sure let me say she was overdoing it a little, but in her defence i was just off camera making signs and trying to chat to her while she was trying to think about what she was saying/ doing etc. the lifting/ lowering is really for the initial stage of filling before the engine is started to get as much coolant into the head/pipes as poss. once this is done the engine is then started, raise the revs and the pump empties the funnel towards the exp tank, when the revs are lowered the funnel fills thus the term seesaw, continue until the bottom hose hot, stat open. at this point the throttle funnel effect reverses so be carefull.
( this is starting to sound a little like the factory method with a little twist and a funnel
).steves already started talking to chell about adding his animations etc to make the vid clearer, user friendly, has anyone any other ideas on how it could be improved/remade or should we just let peeps read the manual
the main reasons i would not fit an auto bleed are as follows.
the main airlocks in my opinion are the head top, the top of the front heater matrix, and the main one is the top hose down pipe to the rad, this is why the flow gets stopped as the air will not go down at this point, and why they fit a bleed titty on the steel pipe to the rad, or is it filled from here ??.
any block in flow at these points will stop the coolant flow to the stat, the stat will not see a problem so wont open but the head will be boiling. so, where do you fit an auto bleed, at the head ? at the top hose ? at the bleed pipe ? or just fit several, or better still just look after your pipes and coolant system.
