hey folks i am in the process of replacing my head on '88 ranger 2.3l
i noticed a rubber hose connected with a clamp under the lower intake manifold assy. my manuals do not show it nor refer to it. the hose was like a capped hose but i can tell the clamp used was not a oem type one. can anyone tell me
what this outlet is or was for it is directly under the coolant sending unit ie...,
same cavity of intake thanks
There might have been a hose that ran from that fitting around the back of the cam cover and forward again to a 'TEE' connnected to a heater hose. It would allow coolant to flow thru the bottom of the intake manifold to warm up the incoming mixture for better combustion. The hose is about 3/8" in diameter.
If you look inside, does the intake have that coolant-dye color?
I belive you are talking about the block breather there should be a recantuglar filter stuck in a hole on the side of the block the 20+ 2.3 I have has them... whatever you do don't block the breather off..
