Hello mate,

Well it could a number of things, it could be a leaky hose or a cracked Radiator or a Core Plug gone, sorry to sound blunt but it well could be one of the things i have mentioned

Which end of the engine? Can you see any coolant dripping from inside the timing belt cover?

If it was the rad, you'll see it puddling on the rad cross member, and as it should have green antifreeze in its easy to spot.

hmmm no nothing from timing belt cover..... i used it all day yesterday but no overheating stayed under 90c ODD. But whn i put water in reservoir within 5 minuts theres a puddle under the left side of enginebut saying that the cover is on so cant really tell but def not frompipes or rad as no dripping

mmmmmmmm

i think its something do with resevoir.... it was removed amonth back when the clip on the powersterring fluid was changed... think it may have something do do with that. Have check hoses to and from there but no leaks. Might take it out and check

Possibly a very daft question but you're not overfilling it are you? Coolant level checking thread

nope.... filled it up again this morning have just com home and guess what.... NO LEAK why are cars so frustrating. How can.... one minute when you pour a bottle of water in, it comes pissing out underneath within 5 minutes and the next tiem you do it, it doesnt leak...

Stupid question but.... any ideas

Water pump would be my guess.

After a run (engine warm), with engine off, run your hand near the bottom left corner of the engine, belt pulley side, and feel for any water coming out.....be careful not to burn your hand.

Ok thanks for that, im off for a run later and will check. So what do you rekon the damage would be to replace...... seems to be one thing after the other this year (maybe time to replace)

If the water pump is faulty, you will be looking at a full timing belt kit replacement as well, people have paid all sorts of different prices to have this job done, if you are sending it to a garage, the cost could be minimum £250, doing it yourself will cost a lot less.
