Hi all,
Had a little browse around the forums but can't seem to find the right answer. My '09 1.5 J10 seems to have sprung a coolant leak but I can't for the life of me figure out where it's coming from, the reservoir is now completely empty after a half hour drive. It's doesn't seem to be from the radiator but more further back, maybe engine?
Thanks in advance for any help!!

Upon further inspection it also looks like it's mostly wet up the back of the engine, but still can't pinpoint what the cause of the leak is.

Sorry, been a mental week and only just getting a chance to look at the car again, yeah it's leaking whilst engine is running then continues for a few minutes after the engine is off. From what I can see one of the hoses at the rear right of the engine is quite wet but difficult to say without taking bits out to gain access.
May try some leak sealer though.

Please dont put any sealer in the system - it can clog things up.
Find the leak and fix it , even if you need to remove a few bits and pieces
The sealer wont fix a leaking pipe , be it rubber or plastic
