Good Morning fellow Mitzy owners, I've been very lucky in having to not post on here for a while. However, sadly that time has come to an end and I am currently losing the love a little with a fairly bad coolant leak that has got me a little stumped. I have tried to add an image attachment but without success, so if I go ahead and explain it I'm hoping there might be someone on here that could potentially point me in the right direction of what I need to repair? I'd really appreciate any advice given chaps!
If I look at the engine bay (face on so drivers side is on my right), the coolant leak is dripping to the right of the oil sump. I can't see any coolant leak from the front where I would find the pump, nor from the radiator. It seems to be to the right (drivers side) and above the oil sump somewhere. It doesn't leak until the engine has fired up and it drips a few times a second so is pretty quick.
Cheers all

Hi,
I have a 2001 so not sure if it's exactly the same.
Have you checked the pipework from the thermostat housing that goes around the rear of the engine. I had a leak here caused by an O-ring failure. It is really difficult to see and the only way I could see the leak was by using a small engineers mirror and a torch. By doing this I could clearly see anti-freeze leaking.
Hope this helps

Hi Jason, thanks I’ll explore that first - it’ll be cheaper and easier than a water pump replacement!
Many thanks

That's a good place to start the search. The leak will occur as the engine heats up and coolant expands and pressurises the system, so begin your search then, with the engine running. |

Thanks Trekker, you hope it’ll be a pipe from the rad or something simple, but no. Thermostat first, pump 2nd |

Even if space is limited, try and clean the suspect area as much as you can. The dye shows up best on clean metal. It will run off oil residue and then it's more difficult to pinpoint the source. |

This sounds very much like what just happened to me a couple of weeks ago. I couldn't find any leakage from the front of the pump although I can say it was a little bit damp, where the leak ended up was in the lower rear bashplate , very hard to find it, probably just towards the bulkhead below the alternator. |

Did you find out exactly what the issue was? This is under the bashplate next to the oil sump on drivers side. |
