Coolent reduced suddenly

Hi....
Can some body help me out in this. I have observed pecular thing in my Logan. The coolent level is reduced drastically from Max level to almost Min. level in just 5 days of driving (approx.165 kms). There was no reduction in coolent level in previous 1600 kms. Has any other loganite faced similar problem?
Which type of the coolent, engine oil, is used in Logan 1.4 GLX

Get it checked at the service station, the tube may have been cut. There can be various reasons for the same, may be a rat or even wear and tear..
Get it checked asap

Take off the oil filler cap and check it for a creamy slimy substance
also check that the OIL level hasnt gone UP
this could be cylinder head gasket ....Do you have a lot of steamy (white ) smoke from exhaust ?

Could be a bad head gasket - But in a relatively new car !

Hoping its not that and a simpler leak in the cooling circuit somewhere.. Please do let us know what it was.

This happened to me once last September, exactly the symptom. Topped it up. Coolant level OK now

Hi,

I have experienced the same in the initial period of driving before my first service. Within a span of two days the coolant reduced drastically. During my first service they topped the same, and ever since the level has remained the same even after 9000Kms of driving.

this car seem to come up with strange problems eh?!

After they chased/butchered/evacuated the rats from the air circulation unit, I took the car and later when I checked the coolant level, it was at the 'minimum' mark. I brought it to half full level by adding fresh water. The next day at the service center they refilled it above the maximum mark. I showed it to the service in-charge and they revved the engine at a high RPM for than 3-5 minutes. The coolant level came down from above maximum to a little above minimum right before my eyes and it stayed that way.
So, if you are noticing coolant level dropping even after 1 or 2 immediate refills then you have to take up the matter with the appropriate people. Of course, as Stu mentioned earlier look for those visual signs to confirm it completely.

In my case the reason was as follows,
There is a tube going in drivers's cabin under the dash board. This is located at backend wall of engine compartment some what at the center of wall. There is a clamp provided on this tube, which in my case has been loose. According the service people the coolent circulates through this tube. When the coolent was heating it created pressure and because of this pressure the coolent used to leak through this tube joint. Took the car to service station and they refitted the tube and clamp and bingo... The problem is solved....
