Certainly does. It's an indicator of a blown head gasket - one or more spark plugs being much cleaner than the rest. -- *Acupuncture is a jab well done* Dave Plowman London SW To e-mail, change noise into sound. |

I thought the dye they used in the now permenantly used antifreeze/anticorrosion stuff was flourescent? Either way it ought to be possible to find the coloured residue from it near the leak. But the colour of the residue may not be the same as the coolant, pretty sure the pink coolant in my car leaves a green residue. The biggest problem with modern cars are all the damn covers and auxillary kit that is shoehorned into the engine bay meaning being able to see the actual engine might be quite tricky. Might not be a problem with a Ford V6 though. -- Cheers Dave. |

Many liquids involved in the manufacture and maintenance of engines also fluoresce under UV light. |

It might be into the oil - but there's no mayo. It might be into the combustion chambers - you say there's "no white smoke" (steam), but how fast is it going? It might be out to the atmosphere - if it's going hot, under pressure, it'll not puddle, but just steam. I've had coolant levels drop rapidly from leaks here, there and everywhere with little evidence in the way of drippage. What engine is it? |

Late to the fray; I thought that was why antifreeze was fluorescent under ultra violet? And pressurising the system cold also allows one to see the pressure dropping and hearing an internal hiss. If its coolant into the head there need not be mayo in the oil, similarly if its coolant getting past a cylinder liner gasket. Coolant lost to combustion chamber can be successfully sealed with one of the water glass based sealants. AJH |

Once up to normal temperature, just shut it off, lift the bonnet and look/listen. Temperature and pressure in the cooling system increases in the 3 or 4 minutes after shutdown as the heat soaks out of the block into the coolant. This may be enough to force the leak and the lack of engine noise and pulley movement may enable you to hear boiling off of minor leaks or see small wisps of steam. -- CB |

Why do you care? If the head gasket has failed the pressure of exhaust gases entering the coolant is enormous and bound to force the water out via the normal pressure release valve - radiator cap. My car overheated the other day. What puzzled me was why the coolant level was normal. Turned out the plastic impeller of the water pump had disintegrated. -- Michael Chare |

well here is a video of the engine .....Found out today that if I don't top
up the expansion tank to the cold fill level which is a couple of inches above the level you see in the video there would appear to be no problem...I must have been overfilling the tank and it blows off and settles at the level you see...no idea why ????? ... https://www.youtube.com/watch?v=1BtK20z_3-s |
