Problems overheating. Have replaced thermostat and the housing for it...fan clutch and water pump. Its still overheating especially going uphill when RPM's are higher. How can I check to see if there is a radiator blockage?
Thanks

Have you flushed the system. You can put some coolant flush in the system follow directions on the bottle and then when you drain it see if a bunch of crap comes out. Also once the engine warms up check the top radiator hose if it a squeese and see if there is pressure in there and if you hear fluid surge thru it. You may have to either replace or take it to a radiator shop and have it rodded and cleaned out.
