CDTi using coolant - Page 2

I picked up a ZT-T on Saturday that reached 123 on the obd temp, I think the stat has failed closed although it was changed along with the waterpump in June 2015?

Guess the fan was going crazy on the high speed setting, that's cooking!

The plastic top cooling hose fittings on my fractured, wasn't a bad job to change, uses a E46 part.

No obvious drips or marks under the car after being parked up, and I can’t see any obvious leaks.

It also starts first turn of the key and runs smoothly, so I presume it’s not seeping out into a cylinder via the head gasket

If left it seems to drop just below minimum and doesn’t seem to go any lower, the previous owner assures me he didn’t ever need to top it up, but did mainly motorway miles so wouldn’t have been affected with the heater not functioning properly at lower driving speeds (That’s my tell-tale I’ve left it too long to top up!)

I’ve ordered a new header tank cap, in the hope it could be that, does anyone else have any ideas?

Hi
Does your car have a fbh ?
I had a similar problem a few weeks ago and struggled to find the leak until i felt under the pump of the fbh
The O ring had failed on the pump causing the coolant to leak .
If it has a fbh shine a torch onto the gearbox and see if there is any coolant or staining on the casing
Regards
