may sound daft but what is it? just found it on an invoice
It's the silver bit above the oil filter, that is plugged into the water system.
It is meant to warm up the oil sooner and help water cool the oil when hot as the radiator / cooling system water goes around there, but how much it does is anyones guess!!
