Last year i found my car to be losing water every 7 to ten days id top her up a bit.id leave the water cap off for 30mins to 40mins letting car run plenty of cycles while squeezing pipes now and again.i noticed once thermostat opened,my autoS swirl pot would bleed constant water into the header tank,that normal?
Reason id bleed the system was because i found sometimes on motorway i had to keep fans on constant but didnt happen all time.PLus stuck in traffic it would take hour or so stand still with fans on before the needle would slowly go above half way and climb slow...
Any thoughts on this be great.no mixing of oil and water etc,no build up in rocker.all clean.what i did find was my fan switch was not fully tight,could see where it had been leaking.i didnt notice this until car was off road..
Also car needs the timing sorted..

Thanks in advance.
