Not sure which belt it is without looking at engine. Because of year and being you don't know service records I would replace all belts. The timing belt is in side the engine that usually just breaks without warning. The hissing could also be the air conditioner compressor which I think is controlled by that belt
Try connecting the battery, while alarm is blaring, lock the door with the button on the inside of the door, shut the door, unlock with the key, then start. It worked on a friends durango.
Cooling radiator may need cleaning and the system may need topping up or new fluid entirely. Any work needs to be done by proper air technitians as it contains dangerous stuff.
Try resetting the body computer,with key away from vehicle disconnect battery for 3 minutes then reconnect it and wait 30 seconds then switch lights on then switch ign on 5 secs later, sure worth a try
blew the piston rod through the oil pan if you have bad luck. if your lucky the oil filter blew off and wont start because oil is low. look under car for where oil is coming from. if there is a piece of metal hanging out the hole your engine is toast

In this model, the TCM is often located near the transmission, mounted on or near the transmission housing. However, exact locations can vary slightly depending on the specific vehicle configuration. It's advisable to consult the vehicle's service manual or a qualified mechanic for precise information on locating the TCM in your specific vehicle.
