How to replace water resorvoir

Hi,
Buy the replacement part.
Loosen-off the securing clamps or clips which hold all the hoses onto the junction pipe.
Remove the damaged part & put the new one in position.
Re-tighten or secure all the clips or clamps holding the hoses in position.
Top up the water in your header tank.
Best of luck

Take the coolant expansion tank out
& check it out (find the Leak)

Could be the tank is cracked
Could be there is a hose leaking

remove the expansion tank and have a look at the seams those tanks have a habit of distorting and start leaking

check your radiator cap whether is the correct in pressure and also if the hose connecting the radiator with the expansion tank is not blogged.

Start with the Thermostat and if that doesn't correct the problem replace the water pump. An Easy test since it is getting into mid spring is to just remove the thermostat and see if that corrects the problem. If it does, get a new one and put it in and your done, if it doesn't get a water pump and put that in and put the thermostat back.

Your washer pump and resorvoir are located inside the drivers fender. You may need to take off the wheel to have better acces but, you will need to remove the plastic fender trim and you will see the resorvoir located inside. The pumps are attached to the resorvoir.

Removal & Installation The fuel pump is located in the fuel tank. The fuel tank must be removed from the vehicle in order to access the pump.

1. Properly relieve fuel system pressure.
   
2. If not already done, disconnect the negative battery cable.
   
3. Raise and safely support the vehicle.
   
4. Safely drain and remove the fuel tank assembly, as outlined later in this section.
   
5. If necessary, detach the quick-connect fittings from the fuel sender assembly and remove the fuel lines.
   
6. Remove the fuel gauge sender and pump assembly by turning the cam locking ring counterclockwise. It may be necessary to use a spanner wrench, such as tool J-24187, to perform this.
   
7. Carefully lift the assembly from the fuel tank, then remove the fuel pump from the fuel gauge sender unit.
   
8. Remove the sender O-ring from the top of the sender and discard.
   
9. Disconnect the pump wires, hose clamps and the clamp from around the pump body.
   
10. Pull the pump assembly out of the rubber connectors.
    
11. Inspect the fuel pump attaching hose for any signs of deterioration, and replace as necessary.
    
12. To install:
    
    1. Push the fuel pump assembly into the attaching hose. Attach the pump electrical wires and fasten the hose clamps to the attaching hose and around the pump body.
       
    2. Place the fuel tank sender and pump assembly into the fuel tank. Use a new O-ring seal during assembly.
       
    3. Place the cam lock over the assembly, then lock by turning clockwise, using a suitable spanner wrench, if necessary.
       
    4. If removed, attach the fuel sender fuel line quick-connect fittings.
       
    When installing the fuel tank, make sure all rubber sound isolators or anti-squeak spacers are replaced in their original locations.
    
    1. Install the fuel tank, as outlined later in this section.
       
    2. Refill the fuel tank.
       
    3. Connect the negative battery cable.
       
    4. Turn the ignition switch to the ON position to pressurize the fuel system and check for leaks.
       

After you drain coolant remove the larger hose at the bottom of over flow tank and the 2 smaller hoses at the top. remove the 1 bolt holding the overflow tank on and remove tank. Next take serpentine belt. Take the 4 bolts off holding on the water pump pulley and remove pulley. Next remove the 5 bolts holding water pump in. Clean water pump housing of old gasket and clean with alcohol or paint thinner to remove any residue. Use a small amount of RTV sealant along with a new gasket and put in the 5 bolts tightening them by hand. Next tighten the bolt a quarter turn at a time until tight.put on pulley, put in overflow tank and attach bolt and 3 hoses .
