How do I change a radiator hose on a 2000 Dodge Durango?

there's most likely some sort of hose clamp on the radiator hose. if not, you may have to cut off the original and put on the new hose, using a clamp. like the kind that tightens with a screw driver. good luck.

a hose is quite easy. most hoses use a screw type clamp or pinch clamp.

1 simple tool is all you need.
screw type is simple a screw tightens and loosens the clamp, use a screwdriver and unscrew. add the clamps to the new hose and tighten.

pinch type may be difficult to get to, with a pair of pliers pinch the two tabs and pull the hose off. add the clamps to the new hose and pinch to install.

first remove radiator cap after the engine cooled. if your radiator has a drain valve open it and drain the coolant into a pan. if there's no valve. remove the lower radiator hose and drain that way. this is messy so do it someplace where can soak up the coolant. it's poisonuos to animals and sweet to the taste so be cautious. to take off your hose 1st place your substitute hose beside it to insure you have the right one. if you have the conventional screw type clamps loosen them till you may be able to slide them freely up the hose. if you have clamp on clamps. get a pair of channel locks and pinch them while wiggling them up the hose. after you have the clamps out of the way. use a flathead screwdriver to seperate the hose from the radiator and the engine, by sliding it under the hose and twisting somewhat. don't attempt to pry the hose off with the screwdriver, just loosen the adhere between the rubber and the metal. next remove the hose by twisting it as you pull it off. once you have it off, take the clamps off and put them on the new hose in the same direction they were on the old hose. to replace hose lubricate the inside ends with WD40 or another lube to make it easier and decrease risk of breaking something as well as your knuckles after you have new one in place, look around the area to see if you knocked slomething loose or broke anything by mistake. some electrical connections in the neighborhood may be knocked loose pretty easily close the drain valve or replace bottom hose. then fill radiator with 50/50 blend of anti freeze/water. repace cap and start motor let run till temp comes up and thermostat opens. watch temp gauge to see it rise, it'll fall when thermostat opens and lets cool water in. while waiting check for leaks, not only in new hose but everything you may be able to see. let engine cool and top off radiator. as generally wear eye protection and dispose of your waste properly.
