There is more than one way to skin a cat
so the old saying goes, same with bleeding the bongo engine , everyone has a preferred method to do this LITTLE job
One way or another depending which you do, is NOT WRONG as long as it works and you do it methodically and don't rush the job.
I personally use the same method that Wheelquick use, which happens to be the same method bigdaddycain uses, Ive had no problems with this method at all.
Wheelquick have changed my coolant twice when Ive had hoses fitted and Ive done it myself once with BDC when i changed a faulty stat last year. And i will be changing the coolant again later this year and fitting a Mazda stat and doing an engine flush as well, BDC will oversee this LITTLE job for me because it works and works well.
That's my twopenneth worth on this subject that i know very little about.
especially when it gets technical.

Oh, and while I remember, I felt my hose this morning and it was warm despite the fact my engine wasn't running. My bottom, on the other hand, was cold.
Should I be worried in case my stopcock has stopped cocking ?

My cock stopped cocking yonks back Mike!
I take back what i said in an earlier post... I had a stonking great vindaloo last week, the following morning my bottom was hot (too hot to touch) Yet this morning, much like you mike, my bottom was cold... but i did find a rather large crack in it.

i bleed my bongo simply through bleed pipe into a demi john lock the bleed pipe off ( home made locking bleed pipe) top up with antifreeze keep repeting untill air has gone this method worked for me when changing my rad and water pump, i had no problems with air locks,,, i dont know the right way or wrong way to bleed a bongo i just know that this way worked for me! jus my opinion
The more options the merrier bro! Keep em coming!
The trick is shifting some air, (as much as is viable) The bongo does the rest!

I've just had the old hose wedged in the crack mike, and you are correct, i flushed out a fair amount of crud! I'm putting this down to mis matching flavours of pot noodle, it would appear that the cheapo oriental imported pot noodles are not, i repeat ARE NOT compatible with a bombay bad boy pot noodle, and serious sludging of the system could result if you mis match! On a serious note... Has anybody noticed there bleed hose shrinks in this cold weather?

So let's get this whole subject into perspective... I have (as have others) Carried out a bit of research in Japan to see if they too have issues regarding our beloved bongo's overheating... (the biggest barrier in easily attaining info is the language barrier)
Computer based translations just don't cut it
The japanese appear not to have an issue with bongo's overheating... EXCEPT, if work has been carried out on the cooling sytem and the follow up bleed is problematic. I maintain, (as i have said previously) A fair share of problems with UK based bongo's can be attributed to the wrong type of coolant being added to the original japanese coolant with dire consequences. Until recently this has mainly been overlooked. Of course, another issue is that old,tired hoses have passed their prime, fail, then perhaps minor undetected damage has occured which would eventually lead to a major failiure (usually the cylinder head). Thankfully, no matter what bleeding technique is employed over here, the bongo has a back up self venting feature that often saves our bacon. The self venting isn't always adequate to remove all the air quickly enough, hence our efforts to intervine with our own bleeding. Bottom line? If the majority of the air is shifted, the bongo does the rest in a healthy system (yeah i said it!)
Now you can debate this with me as much as you like, but the fact remains that's just how it is!
We can argue the toss over the subtle nuances of the finer points of bleeding till the cows come home, the main thing is, we know we need to bleed,we know we have to be vigilant, we know to respect the system, if we look after it...it'll look after us!
good post steve
.all everyone is trying to do is keep the bloody thing running right.
i must admit i dont agree with all stated,but then you wouldnt expect me to would you,
.
in the absence of documented methods of bleeding,we thought there was a need to put something out there,not saying one is better than another,but i think we now all agree that bleeding is vital,however its done.
the thing for me is for someone on the edge of bleeding their bongo has as much info on how to do it properly.
keep up the great work guys

Nice perspective that man......I for one as you know,have contacts in Japan and yep they have no issues unless a mess up is made (rare) with work done on the cooling system....(clip not properly place etc - silly stuff) and you got it in a nutshell with coolant types and mixing.
Not going to dwell on which is best blah blah.....your call Mr/Mrs/Ms Bongo owners.....I go for as near to factory as possible....
As for head issues....all WL-T engined vehicles with or without "complicated" plumbing have had Head cracks/gasket failures so the Bongo is not an Enigma, just a Vehicle that utilises a fussy engine, fussy in the way that the cooling and lubrication systems need regular servicing. If the cooling system is looked after then you will never have an issue,likewise the lubtication and you wont have camshaft issues...... both WL-T known issues..........
Bleeding can be done by factory and various other ways and I for one ain't gonna dwell on it- apart from adding that the WL-T set up in a Bongo/Freda has a de-gas set up yet the BT-50/Ranger uses a "normal" expansion tank type set up - obviously the Bongo/Freda employs that system to eradicate air/gases during hot/cold cycles due to the extra hoses and pipe work as the BT-50/Ranger is what is considered to be conventional......
