Hello,
I have just discovered that the water reservoir from the radiator in my C5 Aircross (1.2 pure) is empty again. This happened before and the car had a new hose fitted only 3 weeks ago at the dealer, under warranty. It was a hassle since they couldn't get the part initially and I wasn't allowed to drive it.
Has anyone else had this problem and know what the issue could be since its probably not the hose? I'm really disappointed and as you can probably tell, I don't know much about cars so I'm a lamb to the slaughter at the Dealers.
Thank you!
water leak again
What year is this car. If less than 3 years it's under warranty.
The expansion tank has a pressure cap on it. This increases the boiling point of the system. As the system warms up the coolant expands into the header tank. The normal level when cold is ½ way up the tank. If over fiilled when cold then the cap will blow and fluid will be lost when the engine warms up. When it then becomes cold the contents left in the tank will be taken back into the engine/rad. So when cold fill to ½ way and put cap on tight. Now go for a run and then on return look at tank, where is the level. It should be above the ½ way mark. If further up then possible cap is duff.
It's possible that the head gasket has gone and engine is taking the water into the cylinders. That's why I asked age.

Hello,
Thanks for the replies.
Okay, so this is very helpful. Its a 2019 plate which I bought in May with only 56miles on it.
There are no drips on the drive but I'll put cardboard under to see if it is dripping from anywhere today.
What is the header tank, is that what I am calling the reservoir bottle?
Its going back in on Monday. They've said I can drive it as long as I keep the water topped up. I will ask them if it is possibly a head gasket issue once I ensure its not leaking.
Thank you!
