So I am about to re-install the engine and transmission, which I am deathly worried about (but that's a whole 'nother thread).
Anyway, since I live in Texas, and haven't once turned the heater on in my car, and the hoses in the engine bay were pretty grungy anyway, I removed everything (I think) heater-related on the engine. I'm not however, removing the heat exchangers, simply because I have nothing to replace them with. What then do I do with the open holes that once belonged to heating equipment? I've included some pictures, indicated with places I am talking about exactly. What do I do with these open holes if I'm going to use them once the engine is back in? Also, is there something I'm not considering in removing the heater-related stuff like I have?
