coolant level sensor slightly leaking?

[akz786]

Searched the forum and a few members have stated the above for the coolant level sensor on the radiator, there does not seem to be a rubber O-ring - either missing or not supplied, there not a a loss of coolant as such just a drip leak in plumbers convention - nevertheless its a leak!

Any ideas?

go on the russian site to see if there should be a o ring.

then order it from the dealers and DIY it.

make sure you dont touch hot coolant and if you use a clean pan you can re-use the coolant, then gaian may be worthwhile flushing and adding fresh.
make sure you bleed the system thoroughly
