I have never bled the air out with the pump running - I just let gravity do it

Neither have i ever had problems bleeding system as there are bleed values at every high point


If you donít have these or donít see them all then yes you would have problems bleeding system

They may have fitted more bleeders since ours was made. God knows it needed them. I'd bought more intending to fit them next time I had to bleed it but then we changed the van.

Brexiters. It's your sh1t now. Whatever happens nationally and internationally you own it. I wish you luck. I think you're going to need all you can get and then some. Friday 13th December 2019.

Be aware that the coolant has a limited life in use after which it looses its anti corrosion properties
( important to retain this corrosion resistance in ALDE aluminium boilers )

Blue change every 2 years

Pink every 5 years

I have googled extensively and been in touch with Alde who want to take 275 from me (plus a lot of diesel to get there) to change the fluid and bleed etc. They won't rent me their special pump as this service is only for Alde agents. Found a guy on youtube who had done the job with a submersible pump form Ebay and a few old plumbing bits to allow him to connect tubing to the pump and into the system at the header tank end. I reckon on being able to do the job for £100 or less and a half to one day day of time because its a bit fiddly

It can be done without a pump, but it's a bugger.

Done it several times on my own vehicle and others (I find its a straightforward and easy job)

Just drain it out of the drain point if you have one and then refill dont forget to take filler cap off to allow air into system

You wonít drain complete system this way but you will get a lot of the old fluid out then refill with new mix or flush it out with fresh water before new solution I just let gravity and use all the bleed values do it , then with everything closed run pump for a while then shut it off and re bleed at every point


Will just cost you a couple of litres of COMMA XSTREAM G40 And if you want to be thorough distilled water (Halfords sell both )

Remember there is a one way valve just outside the boiler in same pipe as the brass auto air extractor should you be trying to blow the fluid out
