Dodge Repair Questions? Ask a Mechanic for Answers ASAP
Good afternoon and welcome to JustAnswer!!!
Is it running hot? Also have you checked the coolant cap to see if the spring and rubber are ok?
If it's overheating then can you tell me if you have any coolant leaks? If you allow it to cool and fill it with coolant and start it with the cap off what happens, does it boil out? I'm trying to determine if you have a leak to cause it to overheat or if the fan isn't working...
Without pressing the throttle will the engine allow you to fill it up and does it draw the coolant in when the thermostat opens? Also if you don't have any leaks and it ran hot then is the fan clutch good, is is drawing good air across the radiator?
Ok if you leave the cap until the coolant level stays consistent after the thermostat opens what happens if you tighten the cap and drive it? When will it run hot and to check the fan clutch see if it will spin easily or does it have some resistance? If you rev then engine when it's overheating do you feel air being drawn into the radiator?
It sounds like you have a bad fan clutch. Since you done have any leaks and it takes about 20 min to overheat I would replace the fan clutch and see if it resolves your issues..
You are very welcome..
