temp at continuose 50 water at 45 , I will leave it till tomorrow as It go t to dark to see the steam , I didnt want to be breathing it in , engine sounds so quiet . when i dropped the water from the rad it was only about the same amount as i have put back in , i wonder if the early 60s oVan's used less for the cooling system? I didnt get a chance to rev it never even thought of it , there is 69000 miles on it which I believe to be genuine. how long does it normally take to heat the engine to wear it would steam , it was steaming but not much, I am puzzled . I will let it run longer tommorow . wht do u think .
