You have a bad water pump. Have it fixed ASAP, it can suddenly get worse and send your fan through the radiator! Pretty easy to replace, should cost you around $200 total
ECT wont kill the engine. If it over heated and you kept driving it. You just might have blown the engine. Put a socket on the balancer bolt and see if you can turn the engine by hand. Clock wise.
is the engine turning over? if not, then you may have expansion of the pistons which have lock them selfs in the bore of the cylinders and because you found the oil diluted with water you may have failed bearings, you may also have had water leak into the cylinder because of a blown head gasket creating a hydraulic lock. in this case remove spark plugs and try cranking engine if any water was traped it will come true the plug holes. Now if the engine is turning over when you try to crank the you may have blown head gasket and posibly a warp or cracked cylinder head. Seeing that you all had a faulty temp gauge or sending unit, that engine may have to be remove and torn down to find the extent of damage done. remove head first check for cracks,flatness and preasure test it.
use 50/50 mixture of coolant/water, use synthetic oil or no more than 5w 30. Change thermostat, make sure fans come on when idleing, otherwise change relay
What exactly is the "round plug type thing" near the firewall [passenger side]? Is it a sensor of some type? I, too, have a coolant leak here on my 2001 Durango; its tucked in rather tightly near the hood/firewall corner. My electric fan is not kicking on; vehicle overheated tonight. (4.7 liter)
the upper rad hose goes from the rad to the thermostate housing. this hose is @2-21/2" the lower hose same size goes from lower rad to water pump. There is a 5/8 hose from water pump to thermostate housing called bypass hose. and you have two hoses from water pump and intake to the heater core. hope this helps if not let me know thanks
