My 2006 Dodge Ram 1500 V-8 5.7 was leaving small puddles of anti-freeze on the ground and running hotter than normal. I was told to use stop leak, which worked but kept running hotter than normal. I have replaced the water pump, thermostat, and flushed the radiator since and still running hot but not over heating. Any suggestions?

Radiator fan clutch may not be right,not spinning properly,and radiator it self,may need replacing or rodded out,the only other thing will cause this,is bad head gasket,

clean the radiator. it is amazing how much bug bits, fuzz, dust and sand get trapped in there. if air cant flow well through the rad, you'll have poor cooling. get the garden hose out with a good pressure nozzle on it. clean the rad fins by blowing through the cracks. careful not to bend fins. if really dirty and water doesnt get enough, you may need to hit it with some acid, then rinse thoroughly.
