No.

There is some kind of vacum pump gizmo that sucks all the air from the header tank but I think only Proper Workshops have those.

Thats what we have used today, bit like brake bleeding when it just pushes new fluid in till it comes out bubble free. We also have a laser heat detector thing which can pick up hot and cold spots on the head to make sure it is all getting cooled not sure how that works yet though will report on that tomorrow.

Hi got all coolant in today, van has been run up to temperature twice till fans cut in and cooled down and topped up, Doesnt seem to be any problems with air but how will i know? We used a laser temperature reader and all readings across the head were all even and heating up at the same rate. Drove the car home through traffic and still no signs of any problems. Am i in the clear?

if the fans cut in when the bottom hose is very hot you should be ok,but if the bottom hose is cool/warm when the fans cut in you still have air in there.

When fans cut in bottom hose was red hot and read about 80 degrees on the laser temp thing, thermostat opens at 82 so that seemed about right. Needed to top up coolant very slightly this morning and drove to work no problems, did seem to warm up a lot faster since changing the stat. Fingers crossed.

If you're topping up the coolant once a week then ask yourself where the coolant goes?? - out of the system (via a leak) and more than likely your floor. Coolant levels hardly go down over a long period of time, let alone a week. You should really get it checked out by a bongo garage : )

Looks like i have sorted it if you wanna check out the previous posts.
Thanks

Sounds like a job well done stuc! Every trace of air can't be bled from the bongo initially, it's quite normal to top up a little after an overnight "cooldown". Any remnants of air (unless hopelessly trapped somewhere) Makes it's way naturally to the top of the system (header/de gassing tank) And is expelled as the cap is removed when cold.

A good rule of thumb guide to an ok bleed is the ability to get good,solid,equal heat from both front and rear heaters alike when up to temp.

A good, healthy system that isn't revved to oblivion post change very often bleeds itself as it's designed to do. Some are stubborn, and need a little help. There are various methods employed by various people to acheive the same end result, an air free system!

Thanks for that BDC, fairly confident it has worked all heaters are nice and hot much better than before. Time will tell.

Not sure if it is that relevant here if your level is dropping however I noticed when I fitted a TV aerial onto the windscreen, I removed the facia from the pillar, rear wash fluid pipe runs through the van, not sure if it rubs or there are joints but it could be a reason for a wet interior also.
