If nobody has one they are/were £145 from the stealers :thumleft: .. just do as Daz states, that's the easiest and cheapest fix .. it's not as if you're topping up coolant every five minutes

Please also note that even if you lay your hands on a replacement tank avec sensor, unless your radiator is new or in very good condition, I'd be wary of swapping them out.

I put in a new OEM rad and when the coolant take was taken out, it took part of the rad with it! :)

Unplug like the boys suggest.

Is that the annoying hose on the underside? Mine was fine when I swapped my tank cost me £30 on eBay and no warning light now. Had it off 3 times since for other work and not done any damage.

How many you "fixed" so far? :-k

You can replace just the tank and reuse the original sensor on some later cars and on others you have to replace the complete tank.

Maybe fill the coolant system with deuterium loaded water? The extra density might manage to float the damn thing once and for all. If that fails, move up to sulphuric acid, and lastly mercury. I'm sure the waterpump will be fine.

Aside from the sensor failing is it common for the tank to actually spring a leak mine is only on 25K miles after being replaced under warranty but it is getting on for 10 years old now and I am wondering if I should include a replacement tank in my collection of essential spares or just go aluminium.

The problem with (nearly all) aftermarket aluminium coolant tanks is that they don't include all the complex internal chambers that provide the liquid/gas separation, which is a key feature of the oem tank.
