Bongo Fury

thought i should change a cracked hose today,thought i would get away with out a bleed..turns out i was dum to think so,luck i had a low and high coolant alarm.van didnt over heat so ok.

so 2mrw i ve got the job of bleeding,and i now live a slope..so would it be ok to bleed with front of engie uphill??

ive done it with front up on ramps and was fine so should be

cool..hope to do it the see saw way but cant get a helper as yet..wife needs bongo for 2mrw!

On the flat is fine...or...front raised.....Wouldn't try it pointing downhill.
Can the wife not help ??
It can be done on your own , but if it's your first time a helper would be good.

well..got my parents coming over to take girls out so will have help!..just now got to find a funnel in halfords.

would it be ok if i drive a couple of miles to inlaws if slowly with heaters on..prob wont warm up by the time we get there.

ps thanks for the videos you guys..got the confidence to do it now

Well all sorted.no more air in there...thanks guys.not half as bad as thought it would be

Now bongo runs cooler than ever,and all heaters hot hot hot.wife noticed that heaters were not that good so looks like changing that cracked hose was a good move.

One thing make sure you have a big funnel.iam off to get one 2mrw.not easy with small one,will carry when going on long trips.along with water and other spares i carry.


Ps haydon you saved my bacon yet again,if i had not botherd with coolant alarm be in a mess right now!!

I think ive found that a slight slope is ok but trying to beed on a hill is not great,hard to get level right after and dont think it gets the same ammount of air out than on the flat.tried both on a hill and on the flat with totally different results...

To be honest, I don't think the level is too critical, providing you OVERFILL, say, up to the flanged part of the expansion tank (25/30mm above the actual 'FULL' mark.

I had a potential problem last year when I was down South, so I called in to Allens Vehicles - Plymouth.
He checked the system and topped up to the flange. He said that the system would kick out any excess automatically.
When I got home some 300 miles later, I checked the level and it had indeed lowered back to the 'FULL' mark, confirming what he had said. AND, it has stayed there ever since.

Having thought about this, and why it should happen, I came up with the following theory:
Under normal conditions, when cold, there is a volume of air in the expansion tank above the coolant.
As things heat up, the coolant expands and the level rises, compressing this air. If the compressed air exceeds a pressure of 1.1bar, then the cap will vent off.
NOW - if there is too much coolant in the tank to start with, the initial volume of air is smaller, and because the liquid expansion is the same as before (which it will be), then the 1.1bar will be reached sooner, chucking out what it doesn't need.
Also, by slightly overfilling, it gives the extra bit of coolant to replace any air still trapped in the system, which HAS to be a bonus.
Makes sense to me (and worked for me).
