how do you replace a waterpump on a 2003 lincoln ls

depends on the motor. assuming you have the 3.9 v8. of course drain the system and remove the thermostat housing and take the belt off. then you can get to it to remove it.

Got to remove manafold to get to the screw on passenger side so go ahead an buy a manafold gasket

My bad that is for the water pump houseing but remember that because that will happen sooner than later when it do get the one they make for a jag it aluminum an that the one you want the plastic one that's on it will turn britle

Can a bad water pump on a 2003 Cadillac ls v8 make the temperature caged go up and down..the car is running hot...about 15min with I drive it
