Fiesta mk6 2010 TDCI coolant leak.

[Sean B.]

Hi all, the coolant leak I have has been going on for about a year now, had the rear coolant pipe changed at the back of the engine, ( after a tip off that they are a common fault), but it still is losing coolant somewhere. A full expansion tank will last around 2 weeks, and you can smell it too, but so hard to track down. Any pointers would be greatly appreciated. cheers.

Radiator or the cap on the tank? 

I had the same problem and added some radweld to the coolant and its never done it again.
