The oil pump is an essential piece of equipment that keeps your Ford Taurus running. It lubricates the engine by keeping the oil circulating. Without this lubrication, the engine wouldn't run. An 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.
Drive your Ford Taurus 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.
Take the engine out and put it on an engine stand then remove the upper intake manifold. Take off the valve covers then the accessory drive belt.
Remove the power steering pump and the alternator. The water pump is the next component to remove, followed by the A/C compressor and bracket.
Rotate the pulley shaft clockwise to remove the crankshaft pulley. It has left-handed threads.
Pull out the oil pan and the oil pump screen and tube. Take off the front cover and the timing chains and remove the crankshaft timing gears. Finally, remove the oil pump, taking note of the bolts you removed and in which order you remove them.
Insert New Oil Pump
Install the new oil pump and put the bolts back on in the same manner you removed them. Tighten these bolts to 71 to 106 in-lb.
Reinsert the crankshaft timing gears, timing chains and front cover. Put the oil pump screen and tube back on, torquing the bolts to 71 to 106 in-lb, and torque the nut to 15 to 22 ft-lb.
Put the oil pan back in, then the crankshaft pulley. Install the A/C compressor and bracket using new bolts for the A/C. Add the water pump, alternator, power steering pump, the accessory drive belt, valve covers and upper intake manifold.
Replace the engine back into your Ford Taurus and fill the crankcase. Start your engine and look for leaks in the area you were working.
Hello! It sounds like the water pump is leaking...But first, inspect your hoses and their clamping points... if you can observe coolant leaking, running from the center of the rear of the water pump then it's time to replace it see diagram below for bolt torquing sequence...Bolts1-7=18 Ft. Lbs....Bolts 8-12= 89 In. Lbs.
1. Drain the engine coolant 2. Remove the Belt 3. Remove the radiator, and heater hoses from the water pump connections. 4.Remove the brace that connects to the A/C compressor to the water pump. 5. Remove the 4 bolts that secure the water pump to the engine.
I hope this helps you, and I wish you luck on your repair.
Before servicing the vehicle, refer to the precautions section.
Drain the cooling system.
Remove or disconnect the following:
Negative battery cable
Accessory drive belt and tensioner
Water pump pulley
Engine control sensor wiring
The water pump bolts are of different lengths and must be installed in the correct locations.
Install the water pump. Tighten bolts 1, 2, 3, 4, 5, 6, 7, 8, 9 and 15 to 15–22 ft. lbs. (20–30 Nm). Tighten bolts 10, 11, 12, 13 and 14 to 72–106 inch lbs. (8–12 Nm). Refer to the accompanying illustration for the bolt locations.
Install or connect the following:
Engine control sensor wiring
Water pump pulley and tighten the bolts to 15–22 ft. lbs. (20–30 Nm)
detach the cable from the negative terminal of the battery then loosen the 4 water pump pulley bolts be sure to do this before removing the drive belt then remove the drive belt, alternator, and remove accessory drive belts and idler assembly bolts loosen the hose clamp and detach the heater hose from the water pump and then remove bolts from water pump they around $36.00 at NAPA
WATER PUMP Removal Disconnect negative battery cable. Drain cooling system. Loosen water pump pulley bolts. Remove accessory drive belts. 1. Remove automatic tensioner. Disconnect coolant hoses from water pump. Remove retaining bolts, water pump and gasket.
Installation To install, reverse removal procedure. Lightly oil all bolt and stud threads, except bolt requiring Thread Sealant, before installing. Apply Contact Adhesive on gasket and install on water pump. 1. Tighten bolts/nuts to specification. Refill cooling system. Check for leaks when finished.
