My car C200 1996 model is overheating. No leakage, fan working alright, hose connected to radiator hot as normal, radiator appears normal. What could cause it to overheat and how can I resolve this problem?

 

lower hose hot too?

thermostat.

 

What does a normal radiator look like?

Is there dirt and debris blocking the airflow?

Are the tubes inside clean?

With the coolant full, and the car running, remove the radiator cap and look to see if there is a steady stream of bubbles. If so, you have a head gasket problem, of a cracked cylinder head or block.

Does the problem disappear if you remove the thermostat?

Is the water pump circulating any coolant?
