1. Drain the coolant until the level of the coolant is below the level of the thermostat.
   
2. Disconnect the upper radiator hose from the water hose connection.
   
3. Unfasten the three water inlet connection retaining bolts and remove the water hose connection.
   
4. Remove the gasket and thermostat from the water hose connection. Discard the gasket.

To install:

1. Clean the water inlet connection mating surfaces.
   NOTE The jiggle valve on the thermostat must be in the up position.
2. Place the thermostat in the water hose connection making sure the thermostat jiggle valve is facing up.
   
3. Install the new gasket and place the water hose connection assembly into position.
   
4. Install the water hose connection assembly retainers and tighten them to 89-124 inch lbs. (10-14 Nm).
   
5. Connect the upper radiator hose to the water hose connection.
   
6. Fill the engine with coolant, start the engine and check for leaks.
   
7. Stop the engine and top off the coolant recovery reservoir as necessary.

3.0L DOHC Engine

1. Drain the coolant until the level of the coolant is below the level of the thermostat.
   
2. Raise the vehicle and support it with jackstands.
   
3. Disconnect the lower radiator hose from the water inlet connection.
   
4. Unfasten the two water inlet connection retaining bolts and remove the water inlet connection.
   
5. Remove the O-ring seal and thermostat from the water inlet connection. Inspect the O-ring for damage and replace as necessary.
   

To install:

1. Clean the water inlet connection mating surfaces.
   
2. Install the O-ring, thermostat and the water inlet connection. Refer to the accompanying illustration If you can-t remember how the O-ring and thermostat are positioned.
   
3. Install the water inlet connection assembly retainers and tighten them to 71-106 inch lbs. (8-12 Nm).
   
4. Connect the lower radiator hose to the water inlet connection.
   
5. Fill the engine with coolant, start the engine and check for leaks.
   
6. Stop the engine and top off the coolant recovery reservoir as necessary.

Good luck (remember to rate this answer).

this requires droping the gas tank out of the vehicle. once the gas tank is out turn the retaining ring and remove the fuel pump/sending unit from the tank and replace. most aftermarket pumps come with a diffrent plug and require some rewiring

if you are talking about the wax ring you remove the floor mounting bolts and replace the wax ring under it. first you want to shut water off then flush to empty tank and with a wet dry vac remove any water left . now you can remove it without any mess.

I think that you have a drain line cloght locate
the ac drain line and uncloght it.
