How to keep my Bongo going for the next 5 years

[psquiddy]

I have a 2002 2.0l Bongo tin top with just over 100k on it. I want to keep it going for the next 5 years so think it would be wise to spend some money on it now to (hopefully) avoid some problems in the future. My shopping list currently is:

Change engine oil
Change gearbox oil
Change differential oil? (Is that just for 4wd?)
Fix the heater (not working)
Replace thermostat
Replace all drop links (Are there 2 front and 2 back?)
Replace all heater hoses
Replace coolant
Waxoyl underside
Re-gas the air con
Get the rear view camera working
Replace break pads

Can you think of anything else that would be worth doing?

Since you're working on the cooling system a new rad might be worth while.

And drive it regularly, vehicles don't like being sat for weeks on end.

Change differential oil? (Is that just for 4wd?

The 2 wheel drive has one diff whereas the 4WD models have two diffs + a transfer box.

Several of those items are normal service replacement type things, which would be replaced at the last and previous services one would hope ? Good maintenance isn't doing it once its failed, but replacing before damage occurs.

changing all the fluids is a standard service item, usually longer services but still important, brake fluid change, power steering as well as the rear axle and gearbox.

anti roll bar brackets and rubber bushes need regular inspection and changing as bongo's are quite hard on these.

petrol and diesels fitted with egr systems also need regular fuel system cleaners put through them to keep them operating at best performance with a cleaner burn it helps keep the entire system cleaner, a egr cleaner also helps stop this from sticking, go on youtube and look at egr cleaning. all the air sensors also need regular cleaning again to keep the fuel system within the desired fuel air mix.
for the diesels, turbo cleaners are also needed especially the later variable blade turbo's which carbon up.

ive just bought a 5 year old toyota from toyota with full service history, its taken me 6 weeks to get the bloody thing cleaned out and running right, didnt want them to do it as they said there are no lights on so theres nothing wrong with it, its been serviced to the book from new by them, but in my opinion it wasnt right, when i got it it did max 45 to the gallon, and would not tick over right, now its clean it does 50. service plans take no account of driving style or conditions, this motor had obviously been used on the once a week tesco run.

maintenance, maintenance.

Cam belt , brake fluid, and check brake shoes.

Keep a good eye on rust prevention

[Bongolia]

Primary thing I would say is rust prevention.
Whip off all the internal panels you can and get copious amounts of protection in there,particularly around the wheel arches inject all the box sections too as many as you can then underneath and do the same there.
Dont want to scare you but if you look at the rust issues on here you can see how badly these things can go.
Best investment of your time in my opinion.

Regularly run a cleaner in the fuel system - I like Millers.

I don`t think rear view camera can be got working, I believe the Mazda one is a different format to UK screens.
Anyone?
Definitely move the waxoyl to the top of the list tho.

It will almost certainly be NTSC with the usual variation for each country, in the Japanese standard the black level is slightly different but a minor tweak of the Brightness control will account for it. See https://en.wikipedia.org/wiki/NTSC-J
More of a problem will be the connector, as its not a standard one but a propriety one to connect video and power, might be easiest to cut off and wire it separately, provided you know what voltage is used to power the camera from the original equipment.
