Not sure what size of engine in my 1997 sable wagon

Not too hard at all, even easier if you have it up on a lift. But if I remember right the pan is easy to get to without having to remove anything else. It is a good idea to go ahead and replace the filter while you are there. Make sure you get the rubber seal out of the valve body when you remove the old filter.

follow your top radiator hose to the engine there should be a metal thing attached with 2 bolts, take them out remove the thermostat either replace the gasket or use high temp silicone to reseal it after you put in the thermostat pointed end up

It is on the top of the transmission. has a large connetor going to it.

Sounds like one of the door actuators for the heater/air conditioning has stripped. Very common problem and a very common complaint.

as i recall, it is on the back of the radiator on the engine side at the bottom, probably under the lower radiator hose. it is a t fitting, probalby really tight, dont break it off. and be sure and have something to hold the coolant and not let it run in the gutter. critters drinking it, especially birds, die from it, and your neighbors get upset when you pollute

Check the bulbs to see if they're good (rare that both bulbs go at same time). If they're good, check to see if there's power to your sockets.
Under your car on the side of your transmission will be your reverse switch. It will have several wires coming out of it. Most likely the switch has died.

Rebuilding the transmission. That's quite a few miles on your transmission and the seals are finally letting go.

Q: Are you wearing your seat belt? Yes? No?

A: No.
Solution: Put on your seat belt!!!!!! Save a life!!!

A: Yes.
Soultion: There has to be a fuse either under the dash or under the hood that controlls the chime.
There is a switch in the seatbelt connecter that controlls the chime. It has either failed or the wireing that carried the signal to shut the chime off has been damaged.

at the base of the head rest there should be a tab that you can push in that allows you to remove them.

not all sables had a harness for cd changer . if it had one it would be taped to harness above fuel shut off.
