First check coolant level and strength. If good condition most likely stuck open thermostat, just follow the upper rad hose to the engine. Remove the throttle cable bracket to access the 2 bolts holding the thermostat housing to top of engine. Make sure engine is cold before removing, you will loss a little coolant when replacing. Other causes could be plugged heater core, with engine running at operating temperature on gage. Follow the 2 heater hoses the the right side firewall (where they go thru into cab) one should be hot and the other warm (if the outlet is cold, heater core is plugged). The waterpump and cooling fan are direct drive off the engine and not usually an issue on this vehicle.
Please check your coolant lavel in the radiator,but check it when engines cool. also check the coolant resevoir for low coolant level. this is usually the problem,just low coolant. no leaks? if leaking,you need to repost where the leaks coming from. or at least close vicinity of where leaks at.please post your questions to fixya.com i am usually here to answer your questions.if not,there are thousands of other techs. here to assist you. thank you for choosing fixya.com
Where is the heat gauge show ,is it in the normal range ie; close to the 100"c. or 195"f.if not change the thermostat .if not check the heater hoses they should be the same in heat wise to the touch.if ones cold and the other is hot you may have a plugged heater core.or check the radiator for level of fluid it may be low in the radiator .
