[Corsa C 2000-2006] Water leak from lower right side of engine block

[CorsaGuy]

Hi guys,

I've got a 2004 1.7 CDTI.

Last night I noticed I had a leak coming from the bottom right side of the engine block (as you look towards the front of the car). I managed to take a video of it today, but because the video is too large to upload I have added a couple of photos showing where the leak is located and a screenshot of the actual leak, showing the hose it seems to be running off.

Does anyone know where it may be coming from? Does anyone know what that hose is?

I will try to find out where exactly the water is escaping from, but in the meantime any help would be much appreciated.

Thanks!

Hi Welcome to the forum.

Sorry I have no knowledge of this engine. But from the video it looks like the wetness you show up until about 1 minute into to the video is just the result of the leak from the larger pipe shown from about 1 minute onwards. Its difficult to tell from the video but there appears to be a major split in that pipe.

I dont know what its called or what its for but it needs to be replaced anyway. I would go into a vauxhall opel parts department and show them your screen shots and video so they can trace the exact pipe in their catalogue. But there could be other leaks now, or coming soon. I'd check the condition of other pipes for splitting and oil contamination before you go as its will be easier to replace them at the same time while the coolant is drained down even if its only as a precaution.
Or remove the pipe and take it in with you.

Other parts factors might be able to supply the part, and the pipe might be a standard size they can cut from the roll if you take the old pipe in or have the measurements.

Thanks for the reply Bugman.

Went into Vauxhall eventually. They replaced it for 88 quid. It was the heater outlet hose and they said it's quite a common fault with this engine.

Hope this helps anyone else who comes across this.
