You obviously bled the radiator after fixing everything up. Did you monitor coolant levels daily after that? How did it behave? 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.

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.
Most problems are usually something simple !
