My coolant overflows from the radiator to the reservoir as soon as my engine gets to temp, causing overheating. I had the radiator drained and flushed 2 months ago, replaced the cap and thermostat, and it appears as if the thermostat is working as the upper hose is full and hot while the engine is running. Is it likely my radiator is clogged? Are there any other explanations as to why my radiator would dump coolant into the reservoir as soon as it gets to operating temperature? Thanks, Frankie
