Fix It

The purpose of the oil pump in a car is to circulate oil through the engine as a lubricant between moving parts. The Volvo S70 is a mid-size luxury sedan that was manufactured by Volvo from 1998 to 2000. It most often had a five-cylinder 2.4-liter engine with the oil pump attached to the front of the engine. The replacement of the oil pump on a Volvo S70 requires the removal of additional engine components to access the oil pump.

Instructions

1

Disconnect the negative battery cable with a socket wrench to prevent the engine from starting. Remove the stabilizer brace for the engine. Disconnect the expansion tank and servo reservoir.

2

Remove the accessory drive belt by turning the belt tensioner clockwise with special tool 999 7109. Disconnect the front cover for the timing belt with a socket wrench.

3

Loosen the lug nuts on the right front wheel with a lug wrench. Raise the vehicle with a jack and support it on jack stands. Remove the right front wheel.

4

Disconnect the upper cover for the camshaft with a socket wrench and remove the timing belt. Disconnect the center nut for the vibration damper and remove the vibration damper. Remove the pulley for the crankshaft timing gear and the front crankshaft seal.

5

Remove the mounting bolts for the oil pump with special tool 999 5455. Install the new oil pump and press it with the crankshaft nut to fully seat the oil pump. Tighten the mounting bolts to 88 inch-pounds with tool 999 5455 and a torque wrench.

6

Complete the oil pump installation by performing steps one through four in reverse order. Tighten the center nut for the vibration damper to 133 foot-pounds with a torque wrench. Tighten the bolt for the engine bracket bolt to 59 foot-pounds. Start the Volvo S70 engine and check for oil leaks.

Designed by Jan Wilsgaard, the Volvo 850 is a compact executive car available in both sedan and station wagon body styles.

The 2002 Volvo S80 features a keyless remote that allows the owner to lock and unlock the vehicle from afar as well as open the trunk. There are situations, however, such as when the battery of the vehicle is dead, in which the keyless remote will not work. In these cases, the owner may access the trunk manually with a key or through the passenger compartment.

Instructions

Using a Key

1

Remove the black cover to the right of the handle cover on the trunk of the vehicle. This will reveal a manual lock.

2

Insert the key into the lock and turn it to the right to unlock the truck.

3

Use the manual to open the trunk.

Accessing the Trunk from Inside

4

Reach behind the back seat to access the trunk.

5

Pull the release control handle on the inside of the trunk to release the backrest. This may be somewhat difficult as you have to feel around for the control handle.

6

Fold the backrest down. You now have access to the trunk. If it is too dark to see inside the trunk, use a flashlight.

7

Pull down the florescent handle on the inside of the trunk lid. This will open the trunk.

The cabin air filter in your Volvo removes dust, pollen and odors from your passenger cabin. In the late 1990s, Volvo started installing cabin air filters at the factory. Volvo recommends replacing the filter every 15,000 miles or sooner, depending on the driving environment. The filter is located under the glove box on the passenger side. Replacing your Volvos cabin air filter is a fairly simple job, and once youre finished you can breathe a little easier.

Instructions

1

Find the cabin air filter panel. The panel is located under the glove box on the passenger side. Using your Phillips screwdriver, remove the two screws to the panel cover.

2

Remove the face plate to the cabin filter housing. Slide the old filter out, keeping it level to avoid spilling any debris that may be in the filter.

3

Install a new Volvo cabin air filter. Slide the new filter into place. Make sure that the arrows on the filter are facing up. Attach the face plate to the cabin filter housing. Reattach the cabin air filters panel with the Phillips screws.

The Volvo 850 is a compact executive car sold on the North American market from 1992 to 1997. Options included several body styles and a choice of engines. This front-wheel drive vehicle requires periodic axle service and occasional replacement of the axle.

Instructions

Removal Procedure

1

Remove the front wheel and the ABS sensor from the steering swivel member. Take out the brake pipe bracket and ABS lead. Unhook the bracket, and let it hang free. Remove the drive shaft center nut. Pull out the split pin from the hub center nut. Use counter-hold tool No. 999 5461 (on models with four wheel bolts) or tool No. 999 5540 (on models with five wheel bolts), and remove the nuts. Disconnect the drive shaft end from the hub.

2

Tap the shaft end in approximately 10 to 15 millimeters, using a plastic or copper mallet. Remove the link arm from the anti-roll bar and the nuts holding the link arm and ball joint together. Unhook the link arm from the ball joint.

3

Remove the drive shaft from the hub. First, twist and pull out the strut. Then tap on the drive shaft end with a plastic or copper mallet to remove it from hub. Clean the metal glue from the spline joint (hub-drive shaft).

4

Pull out the bearing caps from the drive shaft support bearing and the drive shaft gearbox if you are working on the right axle. Take care not to damage the seals in the transmission and drive shaft boot (gaiter). If you are working on the left axle, use prying tool No. 999 5462 to remove the drive shaft from the transmission. Do this by applying leverage between the transmission and the inside of the drive shaft.

Installation Procedure

5

Inspect the ABS sensor. It should be free of dirt. Push in the drive shaft, ensuring that its clip engages in the differential groove. Take care not to damage the drive shaft seal or boots. Install the bearing cap. Tighten it by applying 18 foot pounds of torque.

6

Install the drive shaft in the hub. Apply metal glue to the drive shaft splines. Twist and remove the strut, and fit the drive shaft into the hub. Use a socket wrench to hold the link arm down. Install a new drive shaft nut, and hand-tighten it.

7

Install the link arm onto the ball joint. Use new nuts. Ensure that the mating surfaces on the ball joint and the link arm are clean and free of grease. Tighten the nuts to 13 foot pounds, plus an additional 120 degrees. Apply a rust proofing agent to the areas between the ball joint, link arm and nuts.

8

Link the arm to the anti-roll bar with new nuts, and tighten them to 37 foot pounds. Tighten the drive shaft center nut. Use counter-hold tool No. 999 5461 (on models with four wheel bolts) or tool No. 999 5540 (on models with five wheel bolts). Tighten the nuts to 89 foot pounds, plus an additional 60 degrees. Lock the drive shaft center nut. Use a chisel to tap the locking nut flange into the drive shaft slot.

9

Install the brake pipe/ABS lead bracket. Ensure that the ABS sensor seat is absolutely clean. Clean the ABS sensor with a soft brush, fit it onto wheel shaft and tighten it to eight foot pounds. Install the front wheel. Ensure that brake disc and pad contact surfaces are clean.
