Question about 2000 Dodge Caravan
I need step by step instruction on how to replace the oil pump assembly on 2000 Dodge Caravan 2.4L
Remove the Oil Pump
Drive your Dodge Caravan 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 and engage the parking break so the car doesn't roll.
Disconnect the negative battery cable on your Dodge Caravan. Drain the engine oil and coolant into separate pans. Take the vehicle off the ramps or lifts. Remove the accessory drive belts and use an engine support tool to hold the weight of the engine.
Take out the right engine mount and bracket. Take off the timing belt cover and loosen the bolts on the timing belt tensioner. Remove both the tensioner and the timing belt then raise the vehicle back on the ramps or lifts.
Take out the oil pan assembly and remove the oil pump pick-up and the O-ring. Take the crankshaft damper out with a good puller. Use a puller to also draw the crankshaft sprocket from the front of the crankshaft.
Loosen the bolts on the oil pump and take them off. Remember where they were since you'll need to replace them later. Unscrew the relief valve.
Install the New Oil Pump
Clean all the parts to remove contaminants and debris then install the inner rotor. Make sure the chamfer faces the cast iron oil pump cover on the back. Torque the bolts to 105 in. lb.
Install the relief valve, followed by the spring, gasket and cover cap. The cover cap should be tightened to 40 ft. lb.
Fill the rotor cavity with clean engine oil to prime it then insert a new O-ring seal into the oil pump. Put Mopar Gasket Maker or equivalent anaerobic type gasket sealer on the flange of the oil pump body.
Align the oil pump rotor flats with the flats on the crankshaft and install the pump slowly, tightening the fasteners to 20 ft. lb. Add the new front oil seal and install it with the spring side facing the inside of the engine. Even it out with the engine cover.
Install the crankshaft sprocket with the special sprocket tool. Put on the oil pump pick-up tube and O-ring and torque the bolt to 20 ft. lb.
Insert the oil pan and install a new oil filter. Lower your vehicle then install the timing belt and covers and crankshaft damper with a tool specialized for the 2 mm by 1.75 by 150 mm bolt. Tighten the center bolt to 105 ft. lb.
Put on the accessory drive belts and adjust them to the right tension. Put on the engine mount and bracket then take out the engine support tool.
Add fresh oil to the engine and refill the cooling system. Use a 50/50 mixture of clean, ethylene glycol antifreeze and water in the cooling system. Start your engine and check for leaks.
