I just saw your post. I was wondering about waterless antifreeze and any possible issues. We had our heater core redone bu Fusicks: I better check with them about that now! Heater cores seem to be my enemy. Every car we have restored – if we did not do the heater core too: sure as shooting the darn thing would start leaking a year or so later.
Other than that: how do you like the waterless antifreeze? We are just about to re-install the engine in our car after having it rebuilt.
