Yes, please check out this youtube video as it will help you put some of this dye in your system, take it for a good drive and then take a black light and check for leaks with some good glasses some of the kits come with. It would also be burning it if you don't see any leaks but this dye will assure you if you have any.

Make sure you have enough antifreeze in there (50/50 mix. Buy a tester for a few bucks).
Otherwise your system will rust out, gaskets will fail, pump will fail etc. Not to mention engine might burst in the winter.
tell me what else we need to replace
The replacement game doesn't work, as you already found out.
The leak could be anywhere. What you need is proper troubleshooting to find it. Watch the video I posted.
So tell me what else we need to replace.
The approach you are trying is known as the "parts cannon" - just shoot parts at the problem. That rarely works, proper diagnosis is needed first.
There's simply no way to know what you might need to replace without first diagnosing the leak via pressure testing and/or UV dye as shown in the "How to find a coolant leak" video already provided.
Yes we know this. But wr néed to find out the problem so we dont use water. Water us better than no antifreeze. So tell me what else we need to replace. Were liosing coolant every 2 weeks. Water stays 6 months. I'm askimg for help. Not what will happen. We know that
