I still do not think that is the case, I had overheating problems until I fit a new thermostat and do not believe the japaneese would have a large variation in temperature going to the head, it is not there way of doing things

SEE PREVIOUS EDIT, WHICH RELATES TO THIS POST, WHICH HAS BEEN EDITED:
OOp's. I did say earlier that if I have misunderstood I apolgise!!
Well I did and I do.
Dandywarhol has consulted Al the orical and I am sure he will post a reply explaining all. Sorry again but it did get you going. I had a red herring in my tank. I will shut up now on this subject

Ah that explains things, Thanks Haydn -that now makes sense to me

so the flow changes direction???? is that possible??

Flow goes down the radiator, hot at the top, cool at the bottom

It can't change direction because it is pumped round the system.

Hey I agree

Makes sense

Should we now lock this thread, or let it run as long as Coronation Street???

Give it another day in case we get back to constructive ideas.

Don't you dare lock it!

Its only by discussion that some things get sorted, there are two or three determined people on this lead at the moment and if you leave them to it instead of coming up with red herrings and duff information they may well just sort it for the benefit of everyone.

Leave them to it.

I think is safe to assume the thermostat opens when the 'thermostat' reached 82+ degrees , the water higher up the crankcase and cylinder head can be a lot higher than this and this is what can cause the overheating etc. I am happy in my own mind that if there was a good circulation of coolant that there would not be any problem.

I have just been up the scrapyard and managed to get an inline thermostat housing and will look into fitting this in the top hose and removing the original thermostat and see what happens. This may take a while but I will report back.

What car did you get this inline housing from?

Woa! Just popped in to have a peek at this thread. I see Dandy and Allan have been on the 'blower' - excellent. Looking back over it, including lots of overheating (how appropriate

) i seems to me that an excellent result has been had. I'm fascianted that the circuit is always running. How very clever, and I thought I had noticed the Bongo heaters giving warm air well ahead of the temp gauge moving (I daresay other modern cars so this too). I see now why a Bongo might not overheat unless the engine is heat stressed, with the little circuit and airflow around various bits managing to cope. If the rad and the 'arteries' are gunged up, does the water pump produce high pressure between it and the radiator due to bad flow of water. Does the radiator matrix form a sort of crud filter, with its network of narrow pipes. Crud will also deposit in channels between the pump and the rad due to lack of vigourous flow and scouring. And you might expect (pinprick) failure of hoses in this section of the system. If all or any of this is true, it would be I suspect exactly mimicking the human vascular system.

And I guess that with sluggish flow through the rad, the water coming out of the bottom hose would indeed be very cold. Would this then fool the thermostat when it arrived at it into thinking the engine was too cold for it to open. If so, drilling a few holes in it would allow the old beast to stagger on, but without fixing the basic problem.

Food for thought eh chums?

Has anyone attempted to get to the heater matrix?? is it easy to remove or flush through?

Over heating.
