I have owned my GT 3.2V6 for just under a year now, when I purchased the car the coolant bottle was so dirty you couldn't even see the level, because I had just purchased the car I wanted to change the bottle so I could keep an eye on the water levels to make sure there were no leaks anywhere.
Shortly after owning the car I noticed a leak in the bottom of the old bottle so I ordered a new one to replace, after fitting the new bottle I topped up the coolant and kept an eye on it whenever I checked the oil, probably once a month or so, however the last time I checked the oil the water level seemed low, probably half way up the bottle.
Quite concerned about this I topped it up and thought I would keep my eye on it, so I checked the bottle again today and while it wasn't a perfectly flat surface (not far off) the level was again about half way, feeling underneath the bottle seemed a little moist but there was no signs of a leak as such.
So I drove home from my relatives and thought I would top it up when I got back, while the engine was hot and up to temperature I thought I would open up the bonnet and have a feel underneath the bottle to see if there was any moisture and I couldn't really feel much also the level was back up to max.
Not knowing too much about mechanics but understanding the water level will change when the engine is hot and the system is under pressure, I presumed that when the engine is hot the water level would appear lower??? (am I correct?)
Anyhow if the bottle is leaking, could it be that I have been unlucky with 2 bottles or would some other issue be causing this? I check the oil regularly and there are no signs of water in the oil or around the oil filler cap.
Any advice would be appreciated. Cheers
