How hot is the temp. getting? you could try replacing the thermostat first.

Start with the fans on the radiator. Do they come on when the engine gets hot? does the engine act sluggish when it gets hot or make any unusual noises? Can you have a friend or garage mechanic put a temp sensor on the engine to read the temp? Check the radiator cap, make sure it is on tight or even replace it with a new one. If these do not find the problem, then have the radiator flushed if replacing the thermostat does not fix the problem. Do you have a temp. gauge on the dash or an idiot light only? When does the temp go up? In town in heavy traffic or on the highway also? There are a lot of questions as to why your engine maybe overheating.
