Coolant Level Message
« on: 27 August 2007, 14:24:00 »
Omega 2.2 cd 2001
I get coolant level Message on Display. After having a look at it, I have come to the conclusion that the sensor can not be taken out and the header tank bottle needs replacing as a unit. I wonder if any of you guys can confirm this.
Thank you

You're correct.  :y  I gave my header tank a good clean out with caustic and it 'cured' the message problem for a year or so. I ended up replacing the tank in the end with a new ne from vx - £30 IIRC

Interesting......

My warning msg appeared so I topped up a little and the message went away.  But came back again. I haven't had the system pressure checked , but can't see any evidence of a leak.

Does the caustic trick work because it lets the float move up and down freely???

As far as I could see, my float doesn't! But I would have thought that would have given me a warning msg all the time.  :-?

if you stick your finger on edge of float, can you push it down?

The connector can also fail, esp if some careless mechanic as missed the hole with coolant.

Sounds quite likely - esp pouring from 5L can and no funnel.

Can the connector be cleaned up or is it a gonner?  (I've got a similar sounding problem on my Elite - float is fine - message appears from time to time)

(caustic = caustic soda = sodium hydroxide.   Not nice stuff when concentrated and gets hot if you are disolving crystals - definitely use gloves and be very careful.    Its used in soap so is good at eating grime, but I doubt it will attack limescale - I think you need acid (descaler) for that (sorry - my chemistry is a bit rusty!))

I've never successfully fixed one, I go down scrapper and get replacement.  But only £30 ish from dealer, so don't pay more than £5 for a working one...

The float seems to be resting on the bottom of the expn tank.

Also noticed the beginnings of a circular crack in the tank, around the lid area. Guess I should replace it now before it blows?

Without a doubt ... if it fails under pressure during a run you could have a serious overheat problem :(

Apparently a common problem. Sounds like a new tank is in order.
