Hi All,

Looking to get any info / thoughts etc. if available.

This morning it smelt like hot coolant from my D2 TD5, when I checked it after work I have a low level of coolant. I could not see any obvious leaks in the engine bay. had to add enough coolant raise the coolant level about 1 inch.

After the 3 mile drive home, the coolant level had not dropped by any significant amount, but I could see coolant on the under engine crossmember very slowly dripping.

So, has does anyone know of any areas that "normally" fail around the rear of the engine bay? ( pipework?, heater connections? unions?) I am going to have a look on the weekend when I can get it on ramps in the daylight to see if there are any obvious pipes leaking etc. But are there any "hidden" areas where these leaks arise I should be wary of?

Cheers

Don't know the td5 but hope it's not a core plug

This is the coolant plumbing ; check these and unions first ...

otherwise it maybe an engine based leak ...

Some late TD5s have a slightly different layout;
Euro3 layout is slightly different to pre-Euro3 which is shown in the small box at the bottom of above pic ...

This is the Microcat image and it shows some of the items that have 'special build' details, but not all ...

Click to expand...

The three core plugs are fitted to the three centre cylinders on the right hand side of the block...

Usually something has worn a hole in a hose and it'll only spray under pressure ...

Thanks All,

Just ordered some UV dye if it gets hard to find. Once I get a chance to look I will let you know what I find.
Fingers crossed it will be nice and easy, LOL. ( living in hope )

Cheers.

2 things sping to mind - the inlet/outlet pipes for the heater matrix at the rear of the cylinder head and there is a plug behind the exhaust manifold which can be difficult to see.
HTH,
