Hello. My name is ***** ***** I will be helping you today.

Its possible that the bars leak clogged the heater core but if the temp gauge is accurate it may have clogged the thermostat open. I would start with a thermostat and see what that does to the temperature on the gauge. Also if you didnt run it on a radiator funnel after filling it you could have an air pocket in the system. After replacing the thermostat be sure to run it on a radiator funnel to get any air pockets out of the cooling system. Any auto parts store should have them.
