i was wondering how to drain a radiator need help

 

its really easy, you should have a drain plug at the bottom of the radiator or a hose, either way its easy, just make sure you have an oil pan or a bucket to catch it, all you need to do is take out the plug, just like a screw or bolt, or unclamp the hose and let the hose hang into the bucket, while the radiator drains. and dont forget to replace your hoses

 

While to engine is cool, remove the radiator cap (at the top).
Find the drain plug (at the bottom) and remove it.
Drain fluid into a container and replace.
