1.9 CDTI loosing antifreeze

[Maxim007]

Hy all....
I have a Signum 1.9 CDTI (150)...by 2 weeks.

My car is "drink" antifreeze,and i don`t see where it`s go....under the car is dry,in car dry too,the radiator it`s look good,no antifreeze on them.....but antifreeze still go from expansion jar(about 200 ml on 80 Miles).
Where can i look on my car to prevent this issue?
Can be from water pump?
If someone had this problem please give some answers....
Thanks all...

Hi Maxim
if your water pump is leaking you will see leak from timing belt cover running down block (there is a leak off drill hole to let water escape)but you say ther is no leaks under car .this is allmost certainly head gasket failure,the coolant is going out through the exhaust system,you need to have a pressure test done on your cooling system

10x Jonny...I will search somewhere to do a pressure test on cooling system....but if i do the test,what is the minimum pressure,or medium...to see the result on my car....because i wan to know if it`s good or no...Thank`s again.

I want to say i`m not loosing every day coolant...just when i drive much fast (120 - 140 KM/H)....in the city is ok....but when i go out in the motorway...it`s loosing....and when the flash apear in the display(low cooland level) i pull over and when i go out from car,outside come very strong antifreeze smell...from front of car.
I don`t thing it is the head gasket failure,becose if it was....there will no smell of antifreeze in the front of car...i think it squirt somwhere just when i drive fast....and i don`t see where because there is very high temperature and i can`t see where it`s scuirt....

I do the pressure test and it was OK, No losing of pressure.
Two weeks ago I put in the hole behind the expansion vessel about 30 cm of a transparent hose and other end of hose I left to the top of plastic cover on the engine. Today was again lit the lamp "low coolant" on board. When I stop and opened the hood, I found a pond of antifreeze on the cover of the engine and smell of antifreeze fried. I mean two weeks antifreeze was at normal level every day. Today morning I checked again the antifreeze level and saw it was good(normal level), but in this afternoon, after a road of 45 miles the lamp was lit again "low coolant level" on the dashboard. I saw that antifreeze is low but i don`t understand why it go low only when the engine wants.I`m going with the car every day in the city (low speed,max 60 mph) and the level it`s ok every day.But when i`m going a little faster (about 90-100 mph)it`s going away tru the hole behind the expansion vessel...Does anyone know what is the reason for wich I lost antifreeze and I mean that I lose not every day, just when does the engine feel.Later I will come with a FOTO of my top of plastic cover on the engine with pond of antifreeze.
Can be the thermostat decalibrated?Stuck`s?
Or the water pupm?But i think if it was the water pump, it was leaking somwhere near the pump...not tru the hole behind the expansion vessel.
Thnk`s for any responses....and sorry for my english gramatical vocabulary...I write as best I know ....

Somebody know a reason for what i`m loosing antifreeze?
today I had drive about 600 Km....and when I start from home...I`v checked the antifreeze level...and it was OK....After a 100 km light come up in dash board "low coolant"....i pull over and open the recipient of antifreeze and put about 350 Ml in the expansion vessel....and drive away another 500 km and no lamp had lights....now i`m back home and the level it`s OK again...
What the h**l can be this thing?I`v changed the lid of expansion vessel...and still have this problem....
