    The tabs would "probably" sit in the bottom of the tank. They may have plugged up the supply end. I'd pull it and flush that crap out. Hard to say if it is clogging the radiator or heater core. Not real common, but has been known to happen.

    Well my radiator was just replaced and mechanic had to replace the reservoir earlier this spring.I thought I read somewhere that the tabs can clog the heater core.its still baffling me why the temp started fluctuating a year after I had the car.
