Been preaching for yonks that I reckon the Bongo airlock problems eminate from the rear heater box trapping the air - maybe folks will believe me now :wink:
Is this why Wellhouse Bongos, which all have the rear heating system removed, don't suffer the same bleeding problems (if you know what I mean) :?:

I don't think they physicaly remove the rear heater system Trev, just blank off the controls.

Is that a fact? Blimey, didn't know that. Blanking off coolant pipes to the rear heater would be effectively removing them as a potential source of trapped air in the Bongo. Maybe we need to slip some Windeze in our Bongo coolant tanks

I've never used my rear heater anyway. I suppose I could leave the matrix there and join the pipes as near to the engine as possible.

Hi,could you tell me What Is A Low Down Heater. :?
And why should such a low down heater trap air??

Would the system benefit if the Low Down Heater was converted to a Higher position :?

I thought that Wellhouse removed all the gubbins as Trev said & used the "well" that they're located in for water tanks or something?
It's an idea I keep thinking about, there's a lot of space taken up with all the workings & my rear heater/ac hardly ever gets used, could even use the upper air outlet vent spaces as extra junk storage.

The Ranger only has one heater - that is the biggest difference between the respective systems.

Which is why the whole bleeding system has to be got up to full bleeding temperature with both heaters belting out bleeding hot air to ensure it is fully bled.

Just think how easy it would be to bleed your central heating at home if you only had one radiator upstairs - not 5(ish) upstairs and 4 (ish) downstairs?

I can confirm none of the rear heater/ air con system remains in place on our Bongo, other than the upper air vents which don't do anything. There is a waste water tank on the o/s rear - opposite the door (and a fresh water tank on the nearside under the door). The coolant pipes to the rear are blanked off.

The heater matrix is low(ish) down in the back sillarea and can be a possibility for trapped air IMO. The pipes go into it from below.

Rob, that looks like a picture of a Cross Docking Stock. Mike at Wheelquick had to fit one one to my new cylinderhead, maybe worth giving him a ring on 01942217800.

Here's a pic of what Wellhouse do with the space left by removing the rear heater.

I'm going to disconnect mine due to a couple of leaks (see http://www.igmaynard.co.uk/bongo/forum/ ... =3&t=27324) & its good to know it may help with the bleeding process.

With regard to replacing the pipe on the head, it could be pretty well stuck in there due to corrosion between the steel pipe & aluminium head. When I removed the oil transfer pipe from block I had to use freezer spray to contract the steel in the iron block.

Hi
Question: What is a Low-Down Heater
Answer : "Low-Down" in American jargon means someone who isn't very nice. "Heater" is American jargon from the 1920s/30s for a gun...usually a machine gun....machine guns were often called "Typewriters", or "Ukeles"....gunfire was called "Typewriter and Ukelele Music"......
So;- Perhaps a low down heater is someone who isn't very nice shooting at you with a ukelele.... :shock: :lol: :roll: :roll: :roll:
Back to Bongos....If you don't use the heater, why not just run a loop of water hose at the back of the engine, and save some of the hassle. Most of our friends don't want it on when they travel in the back
Cheers
Helen
In the beginning there was nothing , then God said "Let there be Light".....There was still nothing , but ,by crikey, you could see it better.

Many thanks for all of your thoughts. I confess I'd forgotten that I'd posted the question!! :oops: The engine was replaced about 2 years ago (I wasn't the owner then) after coolant problems wrecked original.
As far as I can tell the heating system has not been modified in any way. They simply slapped in a new engine and connected up the pipes - and the rear heater is still intact and has not been modified in any way.
The only way you would know there was different engine in it is by looking at the bill (!) and the fact that the existing pipe elbow does not have an extra output as the bleed point.
If the Ranger cooling system did have a bleed point in a different place - I certainly haven't been able to find it - and as you say - with only 1 heater - I'm guessing it wasn't necessary in a Ranger. To save a whole load of grief which it looks like it'll be to fit this elbow - I'm considering simply creating a bleed point by T-ing off of the feed to the turbo. That hose is pretty short but looks possible.
I think removing the rear heater and capping A/C pipes is an excellent idea. That would certainly remove some points of failure.
Rob
