First make sure the fans work if the don't reply back let me know. Now from a cold engine, start it up and hand feel the top and bottom radiator hoses and heater hoses, all the hoses should be close to the same temperature when it gets hot and the thermostat open, so when the top radiator hose get too hot to touch all the others should fell that way, if the heater hoses are just warm, remove them and flush the hoses backwards and forwards with a water hose, if the bot***** ***** is warm or cool replace the radiator, if the top hose is cool or warm replace the thermostat, if all hoses are hot you'll have to remove the intake because the coolant passages to the heads are probably clogged, very common if the radiator looks rusted. Good luck I hope this helps and please give a positive rating. Thanks
