Coolant Loss

[Alimac]

Hi Folks,
I've got a 12 plate DS3 Sport+ (THP155) with 8,500 miles on the clock. I was driving the car on Sunday and got the dreaded Stop + temperature symbol warning:mad:. It cleared itself immediately and when I got home I checked the coolant level. The coolant header/expansion tank was empty. Interestingly the temperature gauge has stayed at its normal level whislt driving i.e. bang in the middle of the dial. I put about 1 litre of water in to get it back to between the min & max levels.
There is no evidence of a leak when the car is sitting on the drive, but I noticed this morning when I was parking at work that there was a line of drips from under the engine compartment after I reversed into a space.
Anyway, I let the car cool down and checked the coolant header tank and discovered that it had "lost" about an egg cup full of coolant. There has been no loss of performance from the car and it starts first time.
Any ideas what this might be? A water pump issue?

I've not experienced this but a quick search of the forum did find this that might help you determine the issue - http://www.ds3club.co.uk/showthread....y-month-or-two

Basically any fluid loss from the system would be a worry, I'd get it to the dealer to look at asap, especially if you have warranty cover on it

Good luck !

Thanks lfcrul1972. Assistance much appreciated. I'll contact the local dealer and get it booked in.

Could well be the pump as a few had issues- but that was 150s mainly
And when it goes, it goes, so you have to stop. So best checked over
Might be a gasket or seal with any luck
Hit any stones or the like which may have nicked a pipe that's dripping?

Thanks Chris. No, I can't recall hitting any stones and looking under the engine compartment there seems to be a cover under the lower part of the engine. The dealer is collecting it this morning, so hopefully it's something simple. If it's the water pump, I doubt if that's a one day fix!

Update: the car has been into my local dealer and has had the water pump replaced and also the pump drive tensioner (whatever that is!). They are charging Citroen £457. Thank goodness for warranties!

Thanks for the update, these may help others in the future !

As you said it's good when the payment is takend care of under warranty !

Keep an eye on this - mines has been in the garage 5 times since June to get this same problem fixed. They replaced the pump however a week later the problem came back. In the end the thermostat was replaced and all appears to be ok again..

Thanks jecknlaul. The coolant temperature sensor went, so the car's been back into the dealer for a replacement!
