Coolant Leak

636 Views 17 Replies 5 Participants Last post by  Scooby155
My 2011 Gran Turismo has developed a small coolant leak. It only leaks after a drive (of any distance), and only leaks around 50 millilitres each time. Anyone any ideas?
Thank you in advance.

Although a leak can travel, an idea as to where it drips onto the ground/floor to get a general idea as to a starting spot, would be my first move. (front of engine, rear of engine etc)
Mostly below where the Coolant bottle sits - front of engine on right side. Although there is the lower engine cover below which may make it travel.
Not had it up on a ramp yet - just looking for advice to start with. Thanks.

Check the reservoir tank, it's prone to cracking issues, over time.

Due to the manufacturing process, these tanks are vulnerable where the seems are joined. I actually had to hold a paper towel over one of these "spiderweb cracks," engine running, to find my leak. Not very visible just by looking at it.

I don't think the Expansion Tank is cracked. It looks like new. Also it only happens after a drive. And the fluid has also dropped below the seam of the Coolant tank. I initially thought it was just getting rid of any excess Coolant after I had overfilled it.

The cracks can also develop below the seam. I would give it a good 'once over' just to rule it out though....good luck to you. (y)
OK I will do - thanks

It needs to be pressure tested when it is cold...It is leaking after you drive because of pressure...Jason

Hi Jason,
Any idea what it might be?
Thanks.
Trying to diagnosis a coolant leak via the internet is like getting a haircut over the phone..It could be anything..You pressure test the cooling system and then visually look at it for a leak...That can't be done via the internet...It could be a clamp not sealing, a cracked reservoir, or a hose with a pin hole...All you are gonna get on here is an internet guess...Jason
I kinda thought as much. Thanks for your help anyway.
