New (no-name) freewheel replacement, help

Well I want to replace a freewheel on a old bike, it has a shimano freewheel on currently, now to remove it, I am assuming I need to buy the shimano freewheel removal locknut thing, so I can use a good adjustable wrench to remove it without the need for a chain whip tool.

But this is the part I am confused about, I want to replace the shimano freewheel with a freewheel that came with my broke down GMC denali road bike, its a no - name freewheel, will the shimano freewheel tool work with the no name freewheel so I can tighten the freewheel on to the axle? Or Do I just tighten it without the shimano freewheel tool? The freewheel is a no name but was made quite recently, and usually walmart bikes parts are interchangeable. I just dont want to look like a fool when I try to replace the new freewheel and I cant get the job done with my toolset.

You gotta look. Some use 2 pronged tools, some use 4 pronged. A 2 prong will usu. work in a 4 pronger. Some use a rigged type tool.

Look a these images, and you see what I mean.

We need to know more about the freewheel to suggest a tool, like #2 said. Otherwise you'll end up buying about 50 different freewheel removal tools. I can't quite remember what freewheel comes stock on the GMC but it either takes a park FR-1 or a FR-7. They look *almost* identical but the tools are not interchangeable.

If convenient, note any markings on the freewheel and/or take a picture of it with the rear wheel off the bike.

No, the freewheel is already off the GMC Denali, my lbs removed it for me a while back when the spokes on my rear wheel went to garbage. He gave me the freewheel (cogs) to me and said I can use it on another bike, so now I want to use the freewheel(cogs) on a bike that currently has a shimano freewheel on it, and I know I need to buy the shimano freewheel removal tool to get the current freewheel off the bike, my question is how will I put on the new freewheel which is a no name freewheel(cogs) on the bike? How will I tighten it on the axle? and will that removal tool work with my no name freewheel so I can tighten it not loosen it.

You don't need a tool to get the freewheel installed. Assuming that the threads match the hub that you are putting it on (and they probably will) just grease it and screw it on hand tight and ride it. It will get as tight as it needs to be in about 15'. If you're big and/or strong, it will probably get very tight indeed.

Make sure you know what you're asking. Very few new bikes come with freewheels- most come with cassette cogs. They do the same thing, but the parts and workshop techniques are very different. This is good:

GMC Denali road bike = $140 @ WalMart = freewheel and old bike & Shimano freewheel = very likely (but consider the source there is room for error). Just to clarify --- if you have several loose cogs and maybe some spacers or several cogs and spacers together as 1 unit and maybe 1 or 2 loose cogs all with a big hole in the center --- that would be a cassette. If you have 1 unit with several cogs together and on the back side of the group of cogs there is a large threaded section that is screwed into a hub -- that would be a freewheel.
