Can I get some help do I need to warm engine up before I drain the coolant? And can I drain the coolant from under the heat exchanger? I flush it with water until it’s all good. Lmk need some help. Thanks
 
draining the coolant warm is usually the best bet....

The HX usually has a drain plug for the coolant but you have to pull the block plugs to get the majority of the old coolant out.

If you have 'soft' water available, you may be able to get away with flushing it thru the block....and make sure you get the correct coolant to replace the old...
