My 1997 Dodge Intrepid overheats. I've replaced the thermostat, and it continues to overheat. I noticed adjacent to one of the radiator hoses, a ribbed hose that is split. Could this cause the car to...


Now that you've eliminated the thermostat, it could be a number of other things. Don't drive the car too far until you've fixed the overheating problem - overheating can destroy an engine.

That split ribbed hose you see is plastic wire loom - it carries and protects electrical wires, and is not the cause of overheating.

1. Low coolant level
2. Radiator hose split/cracked, causing low coolant level.
3. Head Gasket - leaking, causing low coolant level
4. Thermostat - stuck closed (you eliminated this possibility)
5. Radiator cap - worn/damaged
6. Radiator fins - obstructed by debris/cardboard
7. Water Pump belt - missing/broken
8. Heater Core - leaking, causing low coolant level
9. Intake Manifold Gasket - leaking, worn, damaged
10. Radiator Fan Relay - faulty
11. Radiator Fan Blade - broken, missing
12. Radiator Fan Sensor/Switch - faulty
13. Water Pump - leaking, causing low coolant level
14. Radiator Fan Motor - faulty

My primary suspects would be Rad Fan Relay (#10), and
Rad Fan Switch (#12).

I have a 1997 dodge grand caravan with a 3.8L I replaced the radiator cooling fan relay switch and fuses but when idling for more than 5 mins. the van starts overheating


Water pump impeller could be bad or thermostat is stuck shut. I would change thermostat first,easy to change, cost under $10.00 Water pump is hard to change in this van, you have to remove right tire, then inside wheel well, then loosen 3 top motor mount bolts which will lower engine so you can get to water pump and tensioner.

Overheating Polo


this sounds like a thermostat fault, but also could be the sensor switch to the radiator but is more likely the thermostat, it should be located at the front top of engine, follow the top water hose to the engine and you will find the thermostat housing, also just a heads up, these had a problem when first made, according to the known fixes and problems with VW's the hoses corroded inside and started loosing water, this could be wise to get the system presure checked to...hope this helps

There is a cooling fan switch normally located near the thermostat housing or in the head near the thermostat housing. check this and see if it is defective.

Hi and welcome to FixYa,

Offhand, overheating as you described could be caused by:
  • too soft rubber upper/lower radiator hoses;
  • radiator fan clutch (is one is used) would need additional silica oil;
  • radiator fan relay switch;
  • radiator thermostatic switch for the fan.
A couple of ideas you may want to explore/consider:
  • wire the radiator fan directly to the IGN B+12;
  • remove the thermostat (not applicable in cold climate);
  • check water/coolant ratio (50/50);
  • some radiator fans will only work if and when the A/C or heater is engaged.
Good luck and Thank you for using FixYa.

Pls be informed that due to my current rank and rating, even a Helpful would be detrimental to my status. Should this solution not address your concern, it would be appreciated if you could just not rate it at all. Cheers.
