I thought of something which may affect the survey results.
Whilst there's no denying that Bongos (particularly diesel ones, it appears) have coolant issues I thought to myself that if my Bongo had suffered any sort of coolant issue in the two and a bit months in which I had owned it before I joined the forum it would have completely down to ignorance. I knew nothing of checking header tanks and hoses when I bought it, nor did I know about the temperature gauge being a waste of space. Apart from a cursory glance at the coolant level now and again (once, maybe twice in thos couple of months) I paid no heed to any potential issues as I didn't know there were any.
I am now very careful and do my best to avoid coolant problems.
I wonder how many problems could have been avoided with prior knowledge, how many people joined this forum purely to find out about what happened, and how many people have "always known". Don't know how this would be built into the survey, but ignorance and negligence could play a part in the problems. Wonder how many Bongos would have suffered problems if NO-ONE knew that they could, and we all drove round without coolant alarms, mason alarms and that small degree of paranoia that membership of this forum has instilled in us. All of them?
That's an interesting last para, Alison. Is it possible, in your spare time Ian, to correlate coolant loss/heating problems/head changes, with LCA and engine temp monitor installs?
On the general point, I've posted elsewhere how Wellhouse Motors, ostensibly Bongo supporters, did their very best to sell me anything but a Bongo - "because
they all overheat" (sic). Fortunately, the couple of Bongos they had in (including our statistician's old one they were selling for him), sold us completely on the Bongo as our choice, so after a week of further thought, we simply bought one somewhere else. I have been conscious that, as well as being a bit annoying with their negative and very exaggerated attitude, Wellhouse did me a big favour by at least making me aware that a Bongo is not a trivial purchase.
As a result, soon after getting ours, I fitted a Haydn low coolant alarm and a TM-2 engine temperature monitor. Was losing a very small amount of coolant from the off; so small that I assumed it was normal - it isn't!! Anyway, I couldn't find a cause - until one day, it found me!
The LCA went off (at normal operating temperature, BTW); coolant had dropped just below the tank screw/electrode. Switched off, then on again just to check the TM-2 reading, which had not risen at all. So, coolant loss but no overheating problem, let alone head failure -
thanks to the LCA - FIT ONE!!!
(Cause was an apparent screwdriver nicked top hose at its engine block connection, beneath its Jubilee Clip, caused during hose remove and re-fit, as a part of the pre-delivery cambelt change - these things happen. Clip had held it in check until, under pressure, the split spread beyond the clip covered area.)
