expansion tank seams to be leaking

[tuttyboy84]

I took my coolant sensor out today to clean it and now that works fine but im loosing water from the expansion tank some how its just a drip but a constant drip is this a common problem

[tuttyboy84]

It looks like ive runed the rubber seal so its leaking from the sensor does anyone know if I can get a new o ring or will I need a new sensor

How did you remove the sensor out of interest? I read on here that I need to just pull it but mine felt like it was going to break!

If you have the old o ring a motor factors should be able to replace it.

You have to twist it 90 degrees then pull on it hard and got a o ring sorted now mate
