you have a burnt fan relay...if it were my car i ould run a jumper to the fuse panel so that when you turn the key on the fan will also come on and run.its not hard to do and it will stop the car from overheating
sounds like your air locked inside there should be 2 bleeders one by the thermostat and in the front of the engine near the pulleys you will probably need a 5/16 or 8 mm wrench to crack them open do one at a time while running make sure all the air gets out and you get a steady stream of fluid coming out once it is bled or you think all the air is out go inside the car and see if you have constant heat if you do then all the air is out.also turn on the heater while bleeding it.

That is really quick, like you are getting no water flow at all. Make sure that a radiator hose is not collapsing enough to stop the flow. If possible on that model, take off the radiator cap and shine a light to see if the water passages in the radiator are clogged up with rust or sediment. If this started after the new thermostat was installed, make sure it was not put in backwards.

Hello and Welcome to FixYa.com
you must have the 2.7 liter engine if so the weep hole for the water pump is inside the engine and yes the water pump goes out and leaks anti freeze and water into engine causing it to sludge up. depending on how long you ran engine with water in it depends on how long engine will last. if not long you should be ok. i would remove the oil pan and clean the oil pump screen and pan. the estimate is correct. the water pump is in line with the timing chain. i would replace the chain and guides while in there as well. flush engine after all is done. use the cheap oil to run engine and add flush then drain and add synthetic oil for high mileage engine. I own one and i had the same problem. i drilled through the timing plate a hole and braised a little pipe to the weep hole to water pump so for the next time the pump leaks it will leak outside of the engine.
