Good news on the starter! Maybe it was fed up with all of the attempts at starting last winter and finally gave up.

I still can't fathom that much coolant loss not being a problem.

Yes I am concerned about the coolant loss. At start up, I get white smoke, gas smell and a weak start so I will continue monitoring the coolant.

One More question. When coolant gets into combustion chamber, does some inevitably make it into oil and make oil cloudy or can it make it into combustion chamber without significant amount making it into oil? Cloudy oil would "prove" coolant leak that I can take back to mechanic if needed.

It is not getting into the oil from the combustion chamber. It would most likely be through the head gasket and possibly intake.

So how would water get into the combustion chamber..I gave him a brand new GM cylinder head.

If coolant gets into the oil, it will make the oil into something closely resembling a chocolate milkshake.

Leaking gasket usually, sometimes cracked head.

Car worked yesterday and we drove about 70km round trip. This morning, only a click sound when I tried to start and all coolant in the reservoir is gone. I called the mechanic who told me to put in new fuse and try to start it. I said that with all the water gone, I don't want to try and start it and if the engine is hydrolocked, I might do damage and be liable for it. So I have asked he come to fix it and I hope he does. Still, he didn't appeared too concerned about all the water dissapearing.

Unbelievable! 270km+30 minutes of driving and it is still losing coolant and the mechanic isn't concerned???I would say find a new mechanic, but this mechanic should be held responsible for fixing the problems.

I wonder if I needed the new starter. When he replaced the starter, it didn't work until he replaced the fuse.

I want to know if there is coolant in my oil pan. When I checked the dip stick, the oil was not cloudy but MAYBE lower viscosity as it was dripping off the dip stick more than I remember oil to drip. I assume any coolant would be at the bottom of the oil pan as oil would float above the water. What would be the easiest way of checking for the coolant in the oil. I was thinking of getting a thin flexible tube and putting it down dipstick tube and withdrawing a small sample then adding some oil to it and see if there is separation or getting some fluid from drain plug (bottom of pan) then adding oil to the sample and looking for separation. Is there a better or simpler way to do this ?
