Hello guys, got the coolant warning light about 2weeks ago, when i checked it was 1-2" below the fill level on the coolant tank, i so i topped it up with a bit of water, and was keeping an eye on it.
So booked it in the garage monday, said bring it back today wednesday and they had a look at it and pressure tested it, i was thinking a worn hose or a clip had came lose, but the pressure test didn't lose any pressure and the system was ok the chap at the garage said maybe it's a dodgey bearing in the water pump depeding on where it stops when the car does could lose coolant, said to top it back up and see if it develops any further because he didn't know what he could change at this stage to fix it and wouldn't want to bill me for a water pump if this wasn't the case, so luckily the garage we use for awhile now is ok and didn't charge us.
i've noticed after a long or hot run i can hear the coolant tank hissing like it's pressurising again and noticed some coolant has came out the overflow from the back and onto the back of the engine in minumin amount real small amount.. and that when it's been stood shortly after a run some drops 2-3 comes from the front of the engine drivers side but could be from any other part because of the engine tray underneath and the run off..
The only thing i can now think of is the coolant maybe boiling away and coming out the overflow as gas if this is possible and what would that mean, i'm not very mechanical but it's the only thing i can think of, any ideas?
Thank you, i know it's long winded described best as i could.
