My 30' Town Sedan is doing the same thing after running Thermocure through it.

I removed the fan belt and ran the engine checking for bubbles in a slightly overfilled radiator. No bubbles were seen. When I replaced the fan belt the bubbles returned. Either there is residual Themocure left in the system causing the bubbles, or the water pump is developing them.
