Title: Coolant tank
Post by: engineerkeith on 30 September 2020, 19:10:15
Over the years of operation with Omega's I have had several coolant tank level switch failures.  Is there a repair scheme as I have four tanks with duff switches and now one of my current vehicles is showing a coolant level warning.

You have two effective choices:
A new tank
Bypass the switch, and remember to check the level visually every so often.


The tanks fail, so it it's looking in poor condition, a new one is the 'best' solution. About £50

 Or ask in the wanted section for a s/h one.

That's only really a solution if your neighbour mentions he's got one and tosses it over the hedge for you.

Not the greatest quality tank sensors are they. I fitted a new tank on mine not long before I sold it and the bloody bobble had popped off its stalk within a few months. I tried to fix it but although I got the bobble and plastic washer back on, I had no success in melting/glueing the washer to the top of the plastic stalk. So, I had a nice shiny washer bottle ........... but still had the message on screen, as I didn't bypass it.  ::)

*IF* you can pull it out absolutely perpendicular, you can get to the reed switch and replace. Or I've found some dry joints on them in the past.  I have about a 30% success rate in getting switch out in one piece without snapping the board.

Sometimes its the magnet in the float itself thats lost its magnetism or simply corroded away.  Pop float off, and replace, but you need to weld a bit more plastic to top of the float shaft to deform it back over to keep float in place.

But last one I bought was under £30 trade, and they look nicer, so I tend to do that.


Using a funnel when topping up helps prolong life, as many failures are possibly caused by water/coolant getting split and flowing around to the base of the bottle where the switch is.

Thank you all for the information, being retired with 'nothing to do' I have decided to cut out the switch from the base with a hole saw. Rectify the problem and repair the tank using some good aerospace material.  I hope after pressure testing I might have found an answer, will keep you informed.
