[doberman 152]

Is there a sticky on changing my water pump on my 99 SS if not how hard is it, and what to look for while changing it out.

Step 1
Remove the drain plug to the block coolant and the knock sensor. Place a drain pan underneath the radiator. When the engine is cool, drain the cooling system from the radiator into the pan.

Step 2
Disconnect the negative battery cable.

Step 3
Take apart the electrical connector from the cooling fan and disconnect the intake air temperature sensor electrical connector and the mass airflow sensor electrical connector.

Step 4
Remove the air intake duct, the air cleaner assembly and both cooling fan assemblies.

Step 5
Take apart the water pump, the inlet hose, the water outlet and the outlet hose.

Step 6
Remove the air cleaner assembly, both cooling fan assemblies, the drive belt tensioner pulley and the drive belt.

Step 7
Disconnect the inlet hose and the vent hose and the radiator.

Step 8
Loosen and remove the water pump pulley and water pump bolts and remove both parts from the engine.

Attach the New Pump

Step 1
Install the drain plug.

Step 2
Put in the new water pump, equipped with a new gasket, tightening the bolts to 22 foot pounds on the year 2000 or higher and 18 foot pounds (25 Nm) on the 1999 models.

Step 3
Reattach the water pump pulley, tightening the bolts to 18 foot pounds (25 Nm).

Step 4
Reattach and reinstall all components in reverse order to their removal, tightening the belt tensioner pulley bolts to 37 foot pounds (50 Nm) and the air cleaner assembly bolts to 106 inch pounds (12 Nm).

Step 5
Reattach the negative battery cable and refill the cooling system. Start the car and check for leaks when the engine reaches normal operating temperature.

Shouldnt take long at all, Personaly i would change the thermostat while your in there. Few dollar insurance but either way its your call. Also ensure you get all of the old gasket material off the block.

When I changed my water pump I didn't touch/remove the cooling fans assembly, or the pump pulley to remove it from the car, but I did remove the throttle body.

why should you remove the drain plug to the block coolant and the knock sensor, would it hurt it if i don't?

You don't have to do that...in fact I'm not even sure I understand what "remove the drain plug to the block coolant and the knock sensor" means or accomplishes.

edit: I think he meant to say remove the block coolant drain plug (which you can skip that step if you want). Not sure about the knock sensor??

We did it on a friends car and the fans stayed on and it went by pretty quick
