Hi all

I've read quite a bit on here about the coolant level sensor in the header tank going pear shaped - and clearly mine has done this as the "coolant level" message has just appeared on the dash.  I checked the connection underneath and all good, so next job is to change it.

However, I was just wondering, is it possible to change or repair just the sensor, rather than having to shell out for a new bottle too? - not that I mind having to pay for a new bottle, but its flippin' typical it should need it as I have it up for sale.

I'm sure the sensor has been removed from a header tank or two, but it's hit & miss. A new header looks nicer too

Three of my previous omegas had had that trouble..i just put up with it by clearing it off by the switch...In fact i just bought another omega and the guy told me that it had that fault along with brake pad wear.As long as all is ok its fine

Thanks - the thing never looses any water, and if I were keeping it I'd not worry about it, but I think it would be worth getting it fixed before the next owner has it.

Check its not the float sticking, remove the coolant cap and rotate the float with your fingers, push it down and release when doing this.

Its usualy just crudd and doing this free's it up.

But dont burn yourself.

Mine went wrong last week, the plastic stop on the float shaft parted company with the shaft so float was floating around in the expansion tank, no way to fix so replaced with a new tank. Think I paid £31.00 for a new tank which included delivery and it took me about 20 mins to replace.

Given that there are a couple of faults that can result in rapid coolant loss (HBV failure, etc.), and that for the temperature gauge to work it needs coolant to be flowing through the coolant bridge, I'd say it's well worth ensuring that the coolant level warning is kept working.

Do need to drain the system to replace the header tank ?

Where is best place to get new tank from ? And do they come with sensor ?

Cheers.

No need to drain the system. You can catch the little bit that will drain out & put it back in if you like.

Vauxhall

And do they come with sensor ?

Cheers.
Andy.

It will if you ask for one
