Pipps,

I bought a '96 Bongo about 4 years ago when there wasn't
that much choice. It was 8 seat unconverted. Inside was
immaculate and the body looked good. I had a tow bar fitted,
cam belt change, full service and the underside was already
waxed. The dealer had it SVA'd 12 Months Tax etc. etc. and
3 Months warranty. For all this I paid 10,856 pounds. Not
bad compared to a similar VW.

About 2 weeks after the guarantee ran out, the lower radiator
hose fell off and I had it towed home. My local spanner man
crawled underneath and found the lower radiator hose had
fallen off due to it having no hose clip. He had to replace
all the other hose clips because they were almost completely
rusted through.

About 3 Months later, the plastic top blew off the radiator,
I had a new brass top one made by Sercke. While changing it
I found the wax had covered up some serious rusting underneath.

6 Months later I had to fit a new water pump which had developed
a leak. At this point I thought about parting with it but couldn't
think of anyone I disliked enough to sell it to. So I decided
to persevere with it, it was a pleasure to drive and by this time
the wife (Gawd bless 'er) had got used to driving it.

I am now very careful with the waterworks and have drained and
refilled it with fresh anti-freeze a couple of times. The rust
problems are now becoming worse and the rear wheel arches have
almost completely rotted away. But now it's an old friend, and
at my age I don't have many friends left, I don't want to scrap
it, so if it passes the MOT tomorrow I shall try and do something
about the rust, and the rear brake disks, and the clicking CV
joints, and the.... I could probably go on for ever.

Just over 2 years ago, I bought a late 99 Bongo from a reputable
dealer, low mileage, and almost perfect condition. Expensive, but
it has never been a problem although I regularly change the anti-
freeze, I am probably being over cautious.

A long story, but you did ask.

Grumps.

seems reasonable for a 10 year old motor.

I'm guessing many that have problems with overheating have either never had the coolant changed, and sludging has occurred, causing premature wear on the water pump, corroded the metal pipes in the cooling system, and caused hot spots in the radiator(plastic parts!) and caused extra pressure on the rubber pipes which are probably in need of replacement after 10 years.

Vans that have been serviced outside of Japan may not have had the coolant changed correctly, so when you finally buy the Bongo you were looking at, do the job yourself, priority 1 when you get the van!!

Don't leave it another year to rust away more! In temperature extremes, I'm guessing very cold weather in the UK, then heating the pipes and whole system up to operating temperature puts extra wear and tear on the cooling system.

Sorry to hear the guy above this post had a bad time with his, I guess if they are not fresh imports from Japan, you can expect some rust... even from Japan, some have surface rust, depending on where they came from...

Just to clarify my post above.

When I bought this Bongo 4 years ago I had just suffered
a major setback in the health department and my "Little grey
cells" were not working normally.

The vehicle was imported by the dealer and had never been
registered in this country. I believe the dealer had it wax
oiled before I saw it and the wheel arches were fitted with
plastic arch covers which hid the rust. I can only assume
that the Bongo had been used as a "Beach Buggy" in Japan
and the dealer bought it for peanuts. The wheel arch corrosion
did not show until it extended itself beyond the plastic
covers after some 18 months. These covers are a perfect fit
and are obviously made specifically for this purpose.

When I bought it, the clock showed 32,000 kilometres but when
I subsequently obtained a Japanese auction report, the vehicle
had left Japan with some 84,500 recorded kilometres.

I realised I had been taken for a ride, in more sense than
one, but as I have always excepted the responsibility for my
own decisions I did not complain as the warranty had expired.
After parting with my money I never once contacted the dealer,
you will all probably say I'm stupid and I suppose that's true
but that's the way I've always been and it's too late to
change now.

I have had a lot of work done to stop any further corrosion
and the only thing left is to deal with the wheel arches.
I have no regrets or recriminations, I consider my decisions,
however bad, are the right ones, after all I'm still here
alive and kicking.

Incidentally, the Bongo passed it's MOT yesterday.

Hi Waycar, you have my sympathy.

It never ceases to amaze me that some experts seem to lack basic
intelligence.

As far as the dealer is concerned, it would appear that over the years
he has realised the importance of honesty when dealing with prospective
Bongo owners. This is no doubt due to the members of this forum and
other journals who would quickly promulgate "get rich quick" activities
in the Bongo community. So, live and let live, I am not about to expose
someone who may by now, have become an honest and legitimate
trader.

I also found that after bleeding the cooling system properly, the heaters work earlier than we I first got my Bongo as a fresh import. It had no water in the expansion tank, took 1 litre of water.
I looked at several vans, and all the Bongos I saw has dry coolant expansion tanks, worryingly, just a litre short of showing in the tank. It suggests that maybe the japanese skill in servicing it may vary, or maybe an airlock can develop if you let is run low on water.
