If it is a tube, you will have to yank it out, there is normally a rubber seal which has to be replaced.

My heater not working, i replaced thermostat and radiator hoses, had radiator flushed and rodded, and still no heat. What is wrong?


Too much blockage in heater hoses or heater core.
Bypass valve may be stuck on "bypass" .

1. Remove bypass "Tees", but don't discard.
Replace with straight-through hose fittings.
The core may start leaking under the water pressure since there is no bypass hose.

Once the heater starts working, put Tees back in place. You need bypass protection or the engine will overheat.

My van is over heating and i think my thermostat is bad.i need a location for were it is on the engine


The thermostat is located in the thermostat housing, which is mounted to the coolant crossover tube. The bypass hose is connected to the thermostat water inlet on one end, and to the intake manifold water outlet on the other. The thermostat is not located in the intake manifold water outlet, where the upper radiator hose is connected.

  1. Drain the radiator and recycle the engine coolant.
  2. Remove the upper radiator hose bracket bolt and remove the bracket.
  3. On 1993-98 3.0L engine models:
    1. Remove the bolt from the A/C high pressure line bracket at the front of the engine.
    2. Remove the two A/C accumulator/drier bracket bolts.
    3. Position the accumulator/drier and A/C line out of the way.

  4. Remove the bypass hose clamp and remove the hose from the water inlet.
  5. Remove the four water inlet bolts and remove the inlet.
  6. Remove the thermostat from the inlet.

To install:
  1. Clean and dry the water inlet and thermostat housing mating surfaces.
  2. Apply a continuous bead of RTV silicone sealant 0.08-0.12 inch (2.0-3.0mm) wide to the water inlet mating surface.



NOTE The water inlet must be installed within 5 minutes of applying the sealant.

  1. Install the thermostat in the water inlet, with the jiggle valve at the topmost (12 o'clock) position.
  2. Install the water inlet to the thermostat housing. Install the bolts and tighten them to 12-15 ft. lbs. (16-21 Nm).
  3. Install the bypass hose to the water inlet, using a new clamp.
  4. On 1993-98 3.0L engine models:
    1. Install the accumulator/drier and tighten the bracket bolts to 45 inch lbs. (5 Nm).
    2. Install the A/C high pressure line bracket and tighten the bolt to 45 inch lbs. (5 Nm).
    3. Install the upper radiator hose bracket and tighten the bolt to 34-48 ft. lbs. (46-65 Nm).




NOTE Allow the sealant to dry for at least 30 minutes before adding coolant.

  1. Fill the cooling system. Run the engine and check for leaks.
