This is now driving me metal the other day went out to the van and exspanstion tank was almost empty Puddle of coolant on the floor got that sinking feeling .anyhow had a look and discover the coolant sensor had cracked (feeled happier ) so got new sensor and cap . Ive since came to conclusion new cap is crap and old is ok but the sensor will not stop leaking was advised not to over tighten it and brought what I though was good one it's a febi one any hints be fore I over tighten and crack it

Re: Coolant level sensor fitting
PTFE tape or put a THIN bead of silicone sealer around the mating surfaces. (I am trying to remember what sort of seal is used on them, "O" ring or flat gasket 
)
Just a thought, the tank is not cracked / damaged is it ?
Can happen, been a post about it recently.

Re: Coolant level sensor fitting
There's a fat O-ring seal round the sensor .... as John says I fitted ours with a bead of silicone (belt & braces 
)
