You will need a crank puller which is a specialized tool that does not justify purchase unless you plan on using it a lot. That means a trip to the bike shop which is a good idea anyways as they will have to match up the crank arm for you as they come in sets.You will also need a new set of pedals and there are lots to choose from.

Pedal stripped

You will need to have that crank arm replaced. They do make repair threads, but the price to install is just as much as replacing the crank arm. Your local bike shop can provide the correct parts.

Stripped bicycle pedal

Better replace the pedal and most probably the crank arm as well. Sometimes a new pedal can cut the threads true again on the crank arm but the crank arm may need replacement too, depending on the damage. Remember to fit the correct side pedal. The pedal threads differ between left and right and pedals are usually marked "L" or "R".

How does a helicoil for stripped crank arm work?

I would just stop by a welding shop and have them weld the pedal arm on. You can buy another whole bike for what it costs to get a helicoil like that done. If it's the left hand thread, impossible.

The pedal assembly on my blackwater somehow got stripped always had problem with pedals coming off

If the thread on the crank arms that hold the pedals are stripped, you will need a new set of cranks. That is definitely a job for the bike shop. Make sure the pedals are snug in the arm, Right side pedal has right-hand thread, left side (looking down when you are on the bike) has a left-hand (reverse!) thread.

My right pedal is stripped. how can you repair/replace the part the pedal screws into?

If it's stripped the crank arm will need to be replaced. It's probably more expensive to fashion a repair with helicoils and taps, even if you COULD find a left-handed one for the left side.

Get on your favorite search engine and look for "(your brand of crank) (size)" or just take it to a Bike Shop and let them deal with it. You would need special tools for crank removal anyway.

Left pedal broke can i get replacement?

All depends on if you stripped the crank arm, you may have to replace your crank arm if you rode with a loose pedal. Pedals are sold in pairs, and there are 2 sizes, a one piece crank is 1/2" and 3 piece crank is 9/16", take your bike to the bike shop and they will tell you if you need a new crank arm or not. It will do no good to just replace your pedal if there is a bad crank arm thread, it will not hold.

The crank arm is stripped on the left side of the bike

Yes, the crank-arm could be replaced.
1.You would need to remove the flat nut holding the crank to the frame. And then take out the bearing.
2. A special open-ended wrench is required to remove this nut. Please visit your local bicycle shop for a new crank-arm, and the required tools, also.
3. Put in new crank-arm and its bearing.
4. Grease the bearing.
5. Tighten nut.
6. Give it a test ride.
