Can anyone help please?
I have an R reg CDX manual that is loosing a lot of water (I have to fill it up after about 15 miles) but there are no signs of a leak or where the water is going!!

Cheers,

Dave.

How does the header tank look, is it full of gunk?

Any steam coming out of the exhaust? Would probably be a lot..

Have you got any cream / mayonaise on the dipstick?

Is it a V6 or 2.0 ?

Welcome to the forum M8, daft question but are you over filling the coolant bottle ?

Thanks for the quick replies. Im new to this and very impressed!!
There is no steam from exhaust, or mayo on dipstick, however, the bottom of the header tank looks a bit murky.

Dave Do you have a V6 or a 4 Pot Engine its importaint for the guys to know to help you find the problem

Thanks Craig. It's a V6 2L manual.

Hope this helps.

That's unlikely.

2L (and 2.2) are 4 cylinder, 2.5/2.6/3.0/3.2 are V6

Thanks Craig. It's a V6 2L manual.

Hope this helps.

Not really. 2.0 is a 4 pot, V6 is either 2.5 or 3.0l

[b17urn]

Sorry, my mistake. It's a 4 cylinder 16 valve. Not too hot on these things!!

[Craig_R]

Hummmm Right This is not to scare you but water vanishing with no sign of a leak could be the head Gasket.

Coolent going into the pots thats what happened to mine.

When you start her up in the morning is she alittle rough missfiring and then clear up really quickly after reving alittle ?

Craig

[b17urn]

Not so much missfiring but a little jerky. Sometimes continues whilst driving.

[ians]

As someone else said, what level are you filling the header tank up to?

[b17urn]

Only filling the header tank up to the half way mark then when im driving the 'coolant level' warning displays on the computer. Temp gauge does not go up though!

[Craig_R]

Jerky could be your breathers need cleaning out.

Does it sound rough and deep when reving first thing, i am asking as mine had a Head Gasket leak and the coolent was going into the pot over night and first thing it was rough as the water was burnt off i think it was the front pot on mine number one.

sniff your header tank see if you can smell exhaust gases or the exhaust to sniff for anifreeze, i had a small test done on mine where a vesal with blue liquid is put on the header tank if it turns yellow it has exhaust gases in the coolent.

Also My Header Tank Cap was knacked from the pressure so i was lossing coolent there also
