Did it fall, and did you top up, and if so, at which point (i.e days or weeks) did it stop falling? Could you estimate the number of expansion tanks-worth of topups you had to do ?

As mentioned, when I changed my rad and bled the radiator both hot and cold, I still had to top up for nearly 3 weeks thereafter before coolant levels stopped moving from full, and I'm estimating that it involved 1.5 exptanks worth of extra coolant.

Thank you.


rgds,

After the one post-rebuild bleed required, I had to top off the expansion tank only once the following day. It required approximatley 3-4 lines on the tank to bring it to the cold level during my check (engine cold of course). No coolant level drop thereafter.

I had to do the same thing after I recently had my heater core replaced by my indy mech.
