    Where's my coolant

    My Disco2 v8 on LPG has gulped a bit of coolant.

    Less than a litre but enough to concern me..

    Fairly sure it is coming from the heater core due to the smell of rotting carpet.

    There's none on the ground or anywhere I can see..

    But.... I have checked the oil straight after a run and looked for any froth or signs of coolant. No froth but a few tiny bubbles. I am talking maybe three on the dip stick and less than a half a millimetre across. Oil is a nice healthy colour and smell.

    Nothing in filler neck but fresh oil

    Any other checks I can make before the trip to Redcliff.

    Thanks in advance

    Ian..

    Take out all the spark plugs and check the insulator colour. White to black is normal depending if they are checked after a hot run or a cold start (carbon fouling). If a plug comes up brown then its likely coolant is getting into that cylinder.

    After 80 thou all mine had a nice amount of tan / brown crud on the insulators. Runs 99.99% of the time on LPG and uses no water. ??

    (If anyone is interested, the crud dissolves instantly with spirits of salts applied with a fine brush, then rinse with fresh water)

    Yep, except in this case you're looking for an odd plug out, they don't take long to discolour once the coolant gets at them.

    Lash out on a UV torch and go hunting in and around your feet...where the carpet is giving off that lovely rotting smell...
    If it's green coolant, it'll flouresce like mad

    A more thorough look in better light shows it might actually be one of the LPG coolant connectors.

    There's a bit of green residue there.

    Which is actually good news.
    Levels have remained the same
