Best Answer

check the easy things first.

1. bad radiator cap or no coolant

2. bad hoses

3. leaks in radiator

4. check thermostat (usually good to change this anyway)

if problem is not corrected by these:

5. check fan clutch if applicable ( my Jeep is an 86), the fan should run constantly

6. lastly the water pump.

pay attention to when it tries to overheat.

8. if it only heats up when your stopped, something as simple as a no fan shroud or faulty shroud could be the problem.

hope this helps
