Please help multiple 1995 Blazer problems!

I have a 1995 Blazer with multiple problems. First it started leaking antifreeze. I had to refill the reserve daily. I thought I had a radiator leak so I used the Bars Stop leak and of course that made the problem worse. Now the leak is below the radiator, antifreeze pours right out when antifreeze is poured directly into the radiator and I havent had to refill the reserve at all. On top of that, The heater doesnt work and the temp is over 210. Sometimes when I am driving the car, it wont go past 30mph and when I stop the car and turn it back on it works fine..What do I do..

You need to stop driving it and find and repair the leak before you burn up the engine.

Open the hood and fill it up with water or coolant and craw under the hood or under blazier adn see if you can spot the leak.

If it is in the rad area you may need to remove the rad shroud or rad covering to see it.

Make sure water pump is not leaking and leaking down hose to bottom of rad.

Check rad drain plug and hoses.

If rad core or tanks are leaking you will need another or new rad.
