I am trying to put a 2.3 back together that I did not take apart, I need to know how the heater hoses route especially the one with the metal tube. I already put the AC and alternator on as well as the exhaust and I think I should have put the hose on first.

 

Try going here: https://parts.ford.com/shop/en/us/pa...08/ford/ranger

You can use the VIN or just go thru and select cooling system and hoses make sure to select 2.3l engine if you don't use VIN

There should be diagrams showing hoses and parts and where they are in the engine bay

 

yes, but it is an exploded view and I can't see where it fits.

 

Then have a look at local craigslist or car dealers with similar year Rangers with 2.3l, 2004-2011 should be the same, maybe even wrecking yard
Take lots of pictures
