bought one of these after seeing a video on utube

instructions are to put it in hose runs from firwall heater connection to top of engine

but the bongo is not like a regular car or van

so im unsure

but leaning towards fitting it near the end of the bleed hose to give me a more conventional bleed point

what do you lot think

If your rad is struggling 'cos of built up crud.....cut your losses and fit a new Rad.....not worth risking your cylinder head over.

No amount of flushing will remove crud settled in the bottom of a rad.

Not really sure what benefits this kit gives? It's easy enough to backflush the bongo system just using a hose at various points around the system. This just looks like it's introducing more connections into the system & therefore more potential leakpoints. is this product rated to cope with a pressurised system? How often do you need to flush it? As Haydn says if the rad or matrixes are clogged, best bet is to replace them.
While it's a good idea to do a flush, especially if unsure of what coolant is in there, or changing the coolant type, even a chemical flush will only do so much to shift any crud.

Looks an okay kit to me for single handed flushing with a hose plumbed in..... neat idea...but the instructions show an inline engine which has bulkhead feeds to the heater matrix....
Going to get one for my toolbox...make them Renault 4/5's especially easier to flush as well as some others ......as for Bongo use.... I await my Kit....but it could be good to have the hose pushing water through while coolant pipes get wriggled...

If in doubt fit a new RAD get one on ebay for about £100, I bought one & fitted it plenty of links to advise how to do it plus a fact sheet. I was apprehensive but with all the encouragement from forum members decided to have a go, however Ian G kindly came down from Mansfield to help in an advisory capacity but still got his hands dirty.

The bongo bleeding ritual is something else, read all the links & watch the you tube video, very entertaining.

I made the following adaptor using bits lying around the shed. It allows hose pipe to be connected into bottom of rad to back flush it. Not pretty, but works a treat.

The Bongo rad becomes inefficient and then blocked because the system rarely uses it. A side to side instead of a top to bottom rad would work better and offer less opportunity to block.
How about making the rad work fully during a service by making all the coolant flow through it and bringing the temp up to hot hot HOT. Just make all the flow go through the top hose and not the primary circuit.

For me.....purely in an advisory capacity of course....if system is unknown and on an old rad....then fit a new rad....as that seems to be the main sediment trap in the system and ultimately being the symptom of the outcome of top/bottom radiator plastic tank leaks......
As for the flush kit....good idea as I have said before ....it may be useful for Bongo, I await delivery as getting one for some Classic motors....before I comment....
