I would recommend having the thermostat replaced and the system flushed out. Then you should be good. It's an easy DIY procedure to replace the tstat. Remove the old one, Then I put the garden hose on the tstat opening, removed the lower rad hose from radiator and turnec on hose and flushed it out. A lot of ugly stuff came out. Hope that helps!
