You could also see if the bolts holding the wipers on came loose from the snow and ice. Pop the cover off, loosen and straighten the wipers where they should be and tighten.

I got 2001buick century custom with a 3.1 v6 motor the engine is sideways where is the freeze plug located same with the Plymouth intakes

Your question is worded a bit strangely but I will attempt to answer what I think you're asking. You have a 2001 Buick Century with a Chevy 3.1 V6 mounted transverse (side to side). I believe there are four freeze plugs on that engine block, two on either side and visible from underneath. I don't know how easy or difficult they are to get to. If you change them yourself make sure you don't put tap water in the radiator afterward. Get distilled water from the grocery store for about 99 cents a gallon. It is free of minerals. Tap water is loaded with minerals that calcify and end up restricting coolant flow. Use a good antifreeze and if water is needed only use distilled water.

My `95 Buick Century V-6 overheating. I found the problem to be a leaking freeze plug on the front head, behind the water pump. How can I get at this plug to replace it?

There are many radiator leak stop products that will seal the leak without having to replace the freeze plug. It is the poor mans repair.

I got a 1996 buick century with a 3:1 and its leaking anti freeze some were on the driver side of the motor and i dont no what it is to i can fix it. It didnt leak till it got warm out so i was thinking it...

If the antifreeze is leaking out behind the exhaust manifold then i would say you have a freeze plug leaking . The plug is located on the sides of the engine block. They can be a real job to get out and replace. If you see the leak in the location i described then i would take it to a repair shop for repairs. Have them to inspect all the freeze plugs for damage. Hope this will help you.

I need to replace the 99 buick century side mirror

There is a small plastic piece (triangular shape) at the top of the door panel, opposite of the mirror. It is held in place by a plastic clip. You can gently pop that out, with a flat blade screwdriver or something similar. That will expose 3 bolts with nuts on them. On my 2000 Century, they are 10 mm. Take off those three nuts, and the mirror will come off.
