I bought a 98 ranger with a 2.5 motor, it came without the cylinder head. I'm just now getting time to install a new cylinder head and I'm wondering if anyone knows what this threaded hole is for? It is located on the intake side of the head at the very back.


Also, the people who I bought this Ranger from seemed to have lost all the bolts, so I'm wondering if anyone knows of diagrams or assembly instructions with all the bolts for components that get mounted to the cylinder head?

thanks!

 

That hole is for the oil pressure switch

You will probably have to get disassembly/replacement diagrams/videos on each component to see the bolts needed for each

If you can find a 1998-2001 Ranger 2.5l or Mazda B2500 at a wrecking yard you maybe able to get quite a few of the bolts needed

 

RonD, Thank you for the response!
