Overheating problem

This request is for non-member who is having awful problems with his overheating Bongo.
The Bongo is still overheating after all the following actions have been taken:
Water pump works fine
- thermostat has been tested and works fine
brand new radiator
Has anybody suffered a similar problem? Any help would be most apppreciated.

I fitted my own rad and followed the instructions on filling in the members area. Not had a problem in almost a year. But didn't have a overheating problem in the first place, it only started when the rad went bang or rather splurt

Samuel, I take it you have had the coolant system bled according to the proper procedures to avoid the airlock, and have consulted all the data at

As above + does it happen more when in traffic than on the open road and/or is the scavenge pump cutting in properly when required (the fan you can see when you open the engine covers, beats me why it is so named)?

So it scavanges the hot air out of the engine bay so you don't cook in hot weather.........................

Thanks for your replies guys.
I'll ask him if he has bled the system thoroughly as this seems top of the list at the moment.
Cheers.

You also dont mention if he has flushed the sytem through properly. It is the sludge in the system that causes the problem and if it is still there, no end of replacement parts will fix it, nor will bleeding. The goo gets stuck in the pipes, particularly the rear wee heater radiators and will foil the most adept bleeder

Tom I agree with you, system needs to be completely free of gunge.

Yeah - I had a radiator replaced and it then showed most erratic overheating behaviour. I searched for past discussions of this, and told my garage to flush the system. They did (and then did the correct bleeding procedure) and it has been fine for the past six months.
