I agree to try looping the heater hoses together to check for a leak, vs. removing the whole dash ( which I have done; once). If your car has a/c then you have to get that drained of refrigerant so it can be disconnected from the lines that run through the firewall. As far as I can tell there is no way to remove just the heater unit without simultaneously removing the a/c “box” too.
If the leak there were significant, I would expect you’d see coolant somewhere, though.

I don't wanna sound dumb but how do I loop the heater core lines to check? And wouldnt me doing a compression test tell me if I'm leaking also? Just asking. Thanks for all the help. I'm gonna look under the dash tommro and see if maybe the carpet is wet. Also my car dosnt have AC.

One line goes to the water pipe and the other to the back of the thermostat housing. Take one off and put it to the other. Compression test will test how much pressure you build in a cylinder. Leak down test will tell you where the compression is leaking to. If you’re not seeing smoke, it’s not getting into the combustion chamber.
As this thread is no longer about starting please ask new questions in a new thread. Thanks.
Yeah this has gone left. Lol
