The waterpump is located on passenger side of the car. Its location if you were standing looking from the passenger side at the engine is at the top right of the engine.There is a pully at the top of the engine that has 4 10mm headed bolts should be a non grooved pully.Loosen the bolts on that pully with the belt on once you loosen these bolts but do not remove them just yet.Using a 3/8 drive ratchet find the belt tensioner and release the belt making sure you remember the belt routing.Typically the the belt routing is printed on a plastic shroud that is just above the waterpump. Once you have removed the belt take out the 4 bolts that you previously loosened.Remove that pully now and the waterpump is right behind that. Sometimes the pully sticks a bit so you may need to put something behind it to gently dislodge it.There are 5 bolts on the waterpump the head of these bolts are 5/16 or 8mm remove the the five bolts using a quarter inch drive ratchet.Once this is done you may need to dislodge the pump.A dead blow hammer works well or a block of wood and a hammer could be used in a pinch.This should not require alot of force.Just a few taps should do it you are just breaking the gasket seal at this point.Now that the old pump is removed the old gasket needs to be removed from the waterpump housing. make sure all old gasket material is removed so the new one will seal properly.Take out the replacement pump and and line the new gasket on the waterpump once you have done this remove the gasket so you can adhere the gasket in place with a thin coat of rtv or weatherstrip adhesive.Now you ready to reverse the process to put it back on.Just make sure to line up the five bolt holes and your ready to go. Hope this helps.

It's held down by one bolt right above the timing chain cover. It's next to the head that's facing toward the front of the car.

Hot or cold does not matter, except for comfort. Pliers, fingers etc all the same as long as you can pull it out. Some valves are screw in on one end but this should be obvious (no rubber grommet).

DTC P1860 is a type "A" DTC and indicates a torque converter clutch pulse width modulation solenoid electrical problem. When set it disables shift adapts and inhibits TCC functions such as the lock/unlock when in 4th-OD. Possible flaky TCC-PWM solenoid.
If you have a 4T65E the TCC-PWM solenoid is located under the side cover assembly. Not exactly easy to replace DIY. Engine/tranny has to be dropped down on the sub-frame assembly.
You could check the input voltage (12 volts) and ground/low to the solenoid via the main electrical connector. And check the resistance of the solenoid at the respective pins on the above connector. Not sure what the value is but you can get that from a transmission service shop or the dealer's manuel.
Assuming you have the 4T65E auto transaxle the 20 way electrical connector is located driver's side top. You should see it looking in. Gray connector and the only electrical plug going to the transmission. Twist counterclockwise.
Other than checking the wire harness, and just an example once the solenoid is proven bad and replaced the local AAMCO charges around $500-$600 including the part but cost will vary depending on where you live. Good luck and sorry for the bad news. Keep me posted, be glad to help.

Simply have it replaced, horns on domestics usally stop working as mine did on my 93 lumina, it stopped working and I had it replace and it worked fine after that.
