I just got a new to me 03 B2300 (same as a ranger) and the heater hose lines are not as they should be. 3 of them are plugged off and I have no heat.
I am having a hard time finding a diagram of the factory hoses and part numbers. I would like to just replace all of them and be ready for next winter.
Thanks in advance and God bless.

 

Sound like a heater core had gone bad and the hoses where plugged off.

 

The 2001.5 thru 2011 Ranger 2.3l or Mazda B2300 have ALOT of hoses, lol

The 2.3l DOHC Duratec engine was made to be mounted sideways, transverse mounted, its a Mazda L engine, just FYI
Ford decided to put it in a Ranger with RWD so ALOT of hoses

Here is an ebay search: https://www.ebay.com/b/Engine-Coolan...01/bn_87111687

Make sure its for 2001-2011 2.3l
