just got me a 2009 that was overheating and the owner had put liquid sealant in cooling system,i did a block test and also pressurize the cylinders but was not able to diagnose a blown head gasket..now my issue is that it is building pressure because my radiator is blocked,found lots of hard material coming out when i backflushed the system...im asking if anybody has had this issue before and whats the best solution to fix it...im planning to remove the thermostat and flush the cooling system as much as i can,then i will replace the radiator...im afraid the heater core is plugged up also as i dont have a heater function either..

I'd be concerned about any small passages where the coolant flows. Replacing the radiator and the heater core would be your best bed. Probably the oil cooler too.
