D2 TD5 Dumping coolant out the bottom of the engine.

**Wil2k** · 24th August 2013, 04:44 PM

Hi all,

I need some help here. My Td5 D2 has over recent months had a slow and irritating coolant leak that I have (stupidly) let go too long. I have not really been driving the vehicle much lately so working on it has been a low priority. However I've needed to top up the coolant several times. Recently I topped up ready to do a short trip and it took 3L. Then it ran straight out the bottom of the engine. I couldn't really see where, however it was lower right (passenger side) of the engine.

Today I got underneath and tipped some demineralised water into the reservoir. It ran out the bottom in a torrent. I managed to locate the source, but am having trouble identifying the part at fault. Its like a plug is missing or something. its a round hole that may well have had a screw in plug it it. This would explain the slow leak (loose plug) sudden torrential leak (no plug).

Here's a photo to show the source. The drip circled shows the actual hole.

I think you'll find that's the drain hole for the water pump.
It's a throw away item.
It's driven of the back of the power steering pump.
Here is a recent thread on one that was done not long ago,

Make sure you do all the O ring that JC refers to.

Yes it will be the water pump. Mine started slooow, was hard to find where the water went , then it increased to the point where it was very visible! Replace pump and as JC says the O-Ring.

Can anyone tell me where this o-ring (ERR6811) goes? I look at the rave but couldnt find this o-ring. Thanks.

It fits between the PAS and coolant assembly bracket Item 41 and the cylinder block in the RAVE section -Engine TD5; description ; cylinder block components ; Page 141.
It does not show the O-Ring though and the whole Rave devotes little attention to the bracket that I can find apart from torque values. The 1 bolt is a (mutter mutter ) thing to get at !
Cheers Scott

Thought I would add a pic

Thanks Scott. I will have a good look again in rave and engine on how to remove them.

That's the housing you where going to get that replacement bolt for Gus.
If you remember it's the one that was missing when the head was done.

Replace with genuine or you''ll see it again much sooner . QH items are said to be okay too..
