It could be blocked with disturbed gunge from the coolant system, on the otherhand most of the Bongo's take a good 10 minutes to warm up.

When the glowplug light flashes as opposed to a steady on, then it means the ECU is reporting a fault, the lamp will stop flashing if the fault disappears or is intermittent, use this site for getting the precise error code http://www.philmcfadden.co.uk/MazdaDiagnosticBox.htm

Could be the CV joints on the prop shaft perhaps ?

Provided the hoses are in reasonable condition, vacuum fill methods seem to be pretty good, but causing old rubber hoses and corroded metal spigots to "collapse" is not always a good idea!

Nothing shows on the three most common sites but might be worth a phone call to each of them;

Mine failed back in April, but this was due to unburnt fuel getting into the Cat whilst I travelled back from Cornwall with an ignition fault. I ended up having to replacing the Cat itself, several sources if you use Google and quite a few cheaper as they are made in the country rather than "alleged...

No the ABS only operates during braking and it watches the voltage and continuity on the brake lights for operation, hence why LED's will cause the ABS to fail as there isn't any/sufficient continuity to earth/0v when replaced or all the brake lights have failed. Fog lamp has no affect at all.

Wasn't aware that the Bongo used co-ax for the cable ? The connectors aren't designed for co-ax and the cable externally looks like normal twin wire.

If its a 2001 vehicle then a wire link and a bulb will be required to read the error codes and the information here http://www.philmcfadden.co.uk/MazdaDiagnosticBox.htm only later versions had the now standard OBDII interface. Most ABS errors come down to faulty connectors or damaged sensors. There ...

No the loom is a set of wires encased in wound insulation, there are several different sections that plug together in any vehicle, coming out at various intervals are connectors to feed items along the way. The terminal arm fuse box has a couple of looms as I recall the "B" - Battery and "F" - Front...

The 100 Amp fuse carries a lot of things! However unless you have a burn't out loom it will most likely be the alternator diode pack that has failed, either a refurbed or new alternator required.

I'm not the expert here, but reading the responses its very rarely the gasket its merely the cheapest option for a garage to quote for when explaining the fault. Once the head is off then the crack should be found, usually between the exhaust port and the coolant system hence no oil involved, and ju...

Several points to note here, as you guessed previously discussed; 1. There is already a third spigot on the de-gassing tank for this purpose, its used on the 2l petrol engine, but is sealed (undrilled) on the diesel and v6. Mazda knew something we didn't when they designed it. 2. There is already a ...

But what typically goes wrong with an old Bongo a few months after an overheating repair ? in the summer? it could be seals on the waterpump, could be a pinhole in a rubber pipe, a leak at a joint where metal is rusting, it could be a cracked head from the first overheat which only opens up when ho...
