As its now getting a bit cooler, have started using the heater and in turn have started losing water!

I have searched the forum so know its a common problem.

My symptom is water loss after using the car. No leaks while standing still, no misting of windscreen, no mayo anywhere and no wet carpets.
The previous owner had already replaced the expansion tank with the green cap but that could need replacing?

I do have quite a bit of water vapor from exhaust on start up but thats it.

Waiting for my mechanic to get it on the ramps for a more extensive look around but just in case I need a new rad, I did see a thread somewhere about an uprated rad, but since then I cannot find the thread again.

Therefore does anyone have any info on what that rad is, from where and how much? In addition in case its a water pump is there an uprated one of those or will the standard volvo one be sufficient??

Hopefully it might just be a hose, but again is there any uprated hose that anyone recommends?

Sorry about all the questions but experience counts for alot!!

Thanks,
