Hot water is entering the passenger side of the radiator, but no hot water is entering the inlet side of the radiator. I've replaced the radiator, water pump, and thermostat. The truck is a 1994 Chevrolet Silverado 4WD pickup, 5.7L. The truck overheats.

  • Welcome to Motor Vehicle Maintenance & Repair! Which 1994 Chevrolet? You could be talking about the 5.7 Gen1 SBC or the Gen2 SBC, and depending on the car, could be a completely different solution to your issue. What have you done to the car? May 11, 2018 at 19:49

    What is the actual issue ... is it overheating? (I hate to assume that's the issue.) And was the issue the reason for changing all of the parts? May 11, 2018 at 20:04

    That year uses a left hand rotation water pump (serpentine belt drive) earlier years with v belts used a right hand rotation. Be sure you got the correct pump, they look identical on the outside.

    I am more used to seeing upper/top radiator hose or lower/bottom radiator hose. I am not used to the terms passenger side or driver side with respect to radiator hoses May 12, 2018 at 17:02
