Thanks Peter. I tried steps 1 to 5 above - no significant pressure. Taking the car to the garage today, I can't afford any work but they said they would take a look. Contemplating K-seal.. |

Good move... As I said, the test is not 100%, but for serious leaks in the head gasket it will show results. It is quite possible you have a leak you have not yet discovered, possibly entrained (trapped) air pockets that are bleeding out slowly (that causes levels to drop) and such. I know with one Honda I worked on recently with a bad hose, you would see antifreeze leaking from what appeared to be the water pump. In fact the leak was on the other end of the engine, and the coolant was flowing (somehow, never figured out the path) along the engine to the water pump area. We fixed the hose, and refilled. It took a week of topping off before we got all the air bleed out of the system! What a PITA, fortunately my SIL was good with checking and filling each time he drove. -- I'm never going to grow up. |

I have some good news, she's not dead yet :-) The mechanic quickly established there was no major head blow. Revved the engine whilst checking the exhaust, and considering there is no sludge in oil, no misfiring, or other serious symptom, he reckons the engine should be ok and to drive normally and keep an eye on levels. There was no smoke of any significance. No longer convinced I have a leak either. The coolant seems to have stabilized. I haven't been far, but there is no obvious loss. She does seem to be a bit thirsty, and getting hot quick and staying hot, so I'm not wholly confident yet, but the gauge stays dead on 90 and I'm loosing no coolant.. may have been a lucky escape! I presume the water pump changes speed to regulate the temp, and if the car was overheating I would see that on the gauge? I guess the ECU is still relearning, perhaps that would explain greater fuel consumption... maybe disconnect the battery again? I may upload a picture of the engine bay. I think in a few weeks I will need to flush the coolant completely (I've seen youtube clips on how to flush the radiator and block with a garden house), it would be an apt time to replace some water pipes, plus I've mixed coolants.. all MEG stuff, but different brands. |

Be very, very careful flushing with garden hoses! It is very easy to blow a heater core, or other cooling system part because of over pressure. -- I'm never going to grow up. |

OK, here's the crazy thing.. (I'm probably tempting fate by writing this).. the car is running better than ever. It's like.. There was definitely white smoke out the exhaust, some not-nice-stuff came out from there, but I'm thinking that.. scorching the engine block without any coolant in cleaned out some junk and sediment... or maybe this is stuff out of the cat. Whatever, I cannot feel/see or hear any obvious problems... and the slight pinking I had before at 2.5k-3k has totally gone! > > No longer convinced I have a leak either.

I've lost no more coolant since my last post!

It is very easy to > blow a heater core, or other cooling system part because of over pressure.. OK, I'll admit it.. I've been watching a few Scotty Kilmer videos. I take them with a pinch of salt, he's obviously a bit flippant.. but entertaining to watch (or perhaps annoying depending on your pov). :-) http://www.youtube.com/watch?v=mxm3E5SkHrI |

Tell a lie, coolant perhaps a few cents down.. it is hard to monitor
with an old resevoir bottle .. i usually take the cap off and look in Oil definitely wants changing.. Cheers Peter |
