2000 Ranger. 2wd, auto tranny. 2.5L 4 banger. Heater has suddenly quit working. The vac controlled hot water shut off valve under the hood was removed a decade ago. Have disconnected both hoses going to the core, attached a water hose and back-flushed the core til it runs clean with a hose. Flows fine, all good and clean. New thermostat (195 F). Hooked hoses back to core. Still no heat. Feel the hoses, 1 side gets hot to the touch, the other stays cold. No circulation thru the core but yet the water hose flows water thru the core without a problem. I can take a deep breath and blow my breath thru the core easily as well. Have checked the supply side from the engine and am getting water from it. This thing acts like the water pump isnt generating enough pressure/flow to push the water thru the core or that the bore is blocked...which it isnt as I flushed it and it flows perfectly fine) Have no over heat problems with the motor though. Also the blending baffle in the airbox under the dash works perfectly fine. (Years ago I cut an access panel in the bottom of the airbox for visual inspetion and made an airtight lid to close it.).
What I am finding makes no sense. Other than a 1/4 pound of C4 under the truck and stand back.....any suggestions or ideas?
