Leak and smoke!

Hi guys

I just arrived home and when I turned my engine off, an alarming amount of smoke billowed out from under the bonnet! I thought it was going to go up in flames! I looked in the engine bay and found a leak near the bulkhead behind the coolant header reservoir. The leak was a clear fluid, not red, and the coolant level hasn't dropped. Any ideas what it might be please? I've downloaded an image from the internet to indicate where the leak was.

Really appreciate any help
Thanks,
Paul

Has the brake fluid level gone down?

Sounds like hydraulic fluid to me.

Thanks Giorget, by the way, the second close up photo shows the drip right in the middle of the image. I took the photo in the direction the arrow is pointing in the engine image.

Is it likely to be a split hose or something like that?

Cheers,
Paul

When you say ''the coolant level hasn't dropped'', did you check the level when the engine had cooled down?
Mine had a coolant leak in this area. Turned out to be a leaking bleed valve.

I'll check tomorrow morning when it's light. The liquid did look clear though rather than the red colour of my coolant.

I had a hose replaced on the coolant system last month after a bleed screw blew!

Both coolant and hydraulic fluid will cause smoke when burned or vaporised, but with coolant you'll get the characteristic sweet smell.

Bit off topic, but bloody hell that's a nice clean engine bay. Wish mine looked like that, slap panel flaking with paint, engine cover off, rusted bolts all over the place :ss

He did state that the picture was downloaded from the internet.
Probably a library pic from a brand new car.

Looks like the pipework attached to the ABS unit.

It will be brake fluid, and if you spill it onto a hot exhaust there is a good chance it will ignite.

If you can wash it away with plain water that will confirm it as being brake fluid.

Just wanted to say thanks for everybody's input. I took the car a couple of hundred metres to my local garage who immediately found the culprit. A joint has broken on the coolant system underneath the engine block where a hose goes into something (water pump?). So it had just dumped coolant directly onto the exhaust.
