ENGINE OVERHEATING

2003 Dodge Dakota • V8 4WD Automatic • 89,999 miles

My engine overheats about once ever other month or so. If I forget to check the level and it goes down I notice my heater will blow cool air and my engine will overheat.

My radiator fluid will deplete and overheating occurs. However, I cannot seem to figure out why it is being depleted. Often it seems like it is blown out the overflow. However, lately it seems like it is not circulating as the radiator hose from the radiator to the engine is completely empty; yet the coolant reservoir is full. Once I fill the hose it will not overheat for a long while.

There is no coolant in my oil.
The thermostat is brand new.
The Filler neck cap is new.
The Water pump is new.
Coolant system has been recently flushed.

You need a pressure test to start. It has a leak and must be found.

You need a leak down test to verify a head gasket due to constant overheating.

Have the radiator flow tested to make sure it is not clogged.
