The oil pump removal procedure for Plymouth Voyager 2000.
A oil pump is usually located in the oil pan. If you want to change the oil pump and replace it with a new one, roll up your sleeves and get ready for some dirty work.
The procedure to remove oil pump is as follows:--

• Drive your vehicle up onto ramps or lifts so you have room to work as you pull out the oil pump. You could also use a jack, but make sure you brace the front wheels so they don't roll. In addition, set the emergency break firmly into position so the car doesn't roll.
• Remove the engine front cover then drain the engine oil and take out the oil pan. It is under the engine and looks like the bottom of the motor.
• Unscrew the oil pump mounting bolts with a wrench and proceed to remove the oil pump itself by pulling it down and out of the engine. Avoid getting any contaminants into the oil pump assembly while removing.

• Disconnect the negative battery cable.Place a drain pan underneath the radiator. When the engine is cool, drain the cooling system from the radiator into the pan.
• Remove the right inner splash shield and the accessory drive belts. Support the engine underneath and remove the right motor mount with the bracket.
• Take off the front cover and remove the timing belt along with the timing belt idler pulley. Also remove the camshaft sprockets, the rear cover to the timing belt and the alternator with its bracket.
• Loosen and remove the bolts to the water pump and remove it from the engine.Install the new water pump after inserting a new o-ring gasket. Tighten the bolts to 105-inch lbs. Make sure that the pump can move freely by rotating it by hand.
• Replace all components in reverse order. Tighten the camshaft sprocket bolts to 75 foot pounds and the timing belt idler pulley to 45 foot pounds.
• Refill the cooling system with coolant and reconnect the negative battery cable. Start the engine and check for leaks when it reaches normal operating temperatures.
