Noise of 2004 Volvo s40 2.4i


Cannot figure out what that part is, but it has a vacuum line connected. Therefore, it should not be functioning unless the engine is running. I would have to guess there is a wire crossed in the key cylinder. The presence of the key should activate the warning system and perhaps deactivate the security system. However, the engine system wiring comes in proximity to the warning wiring behind the ignition switch near the contact reel. It's possible you have a short in that area. I am posting access instructions from autozone.com.
CAUTION Models equipped with a Supplemental Restraint System (SRS), use an inflatable air bag. Whenever working near any of the SRS components, such as the impact sensors, the air bag module, steering column, and instrument panel, disable the SRS.

  1. Before servicing the vehicle, refer to the Precautions Section.
  2. Disconnect battery cable.
  3. Remove steering wheel and air bag module. Refer to Steering Wheel removal and installation.
  4. Remove steering column covers. Remove or disconnect the following:

    Screws from lower coverClip mounting between the upper and lower coversLower steering column coverUpper steering column cover
  5. Remove the contact reel:
    1. Disconnect the left connector.
    2. Remove the screws.
    3. Remove the contact reel.

  6. Remove the ignition switch:
    1. Disconnect the electrical connector.
    2. Remove the screws.
    3. Remove the ignition switch.

To install:
  1. Install the ignition switch:

    2. Connect the electrical connector.
  2. Install the contact reel. Tighten the M5 screws to 44 inch lbs. (5 Nm).
  3. Install the upper and lower steering column covers. Tighten the screws.
  4. Install the air bag and steering wheel. Refer to Steering Wheel removal and installation.

Sorry no pictures
Replacing the Front Heater Core in a 2006 Dodge Caravan.
1 Turn the steering wheel so that the wheels point straight forward.
2 Disconnect the negative (black) battery cable.
3 Drain the coolant by twisting open the valve at the bottom of the radiator. Use a clean container that holds at least 10.5 quarts. You will reuse the coolant later.
4 Remove the panel on the lower left side of the steering column and disconnect the parking brake cable with a pair of pliers.
5 Unscrew the 10 bolts that connect the steering column cover liner to the instrument panel and remove the cover.
6 Turn the key to the LOCK position and turn the steering wheel to the LOCKED position.
7 Unhook the gear shift cable and remove its mounting bracket.
8 Unscrew the two screws that connect the bezel to the instrument panel and remove the retaining clips. Remove the bezel.
9 Remove the two screws that connect the steering column shroud to the column and remove the shroud.
10 Remove the coupler from the steering column and intermediate steering shaft.
11 Loosen the nuts that connect the lower steering column mounting bracket, but do not remove them. Completely remove the two nuts and washers from the upper bracket.
12 Pull out the steering column.
13 Remove the interconnect and bracket that connects the instrument panel to the chassis wiring.
14 Remove the boot from the bottom of the steering shaft.
15 Use locking pliers to pinch off the heater hoses in the engine compartment. Remove the plate covering the heater core (the hoses run through it) and disconnect the hoses.
16 Unclip the connectors that hold in the heater core. Lift the accelerator pedal to enable you to slide the heater core out part way. Press the brake pedal to make room to completely remove the heater core.
17 Replace the heater core. Installation is the reverse of removal. The nuts on the steering column mounting bracket should be torqued to 105 ft. lbs. Torque the pinch bolt on the coupler to 21 ft. lbs.

I have a leak coming from my power steering, and i dont know how to check and see where the leak is and what to look for.


There are two lines coming out of the back of the power steering pump. One is the high pressure line and threaded into the pump. The other is the return line, and has a metal tube coming out of the back of the pump. There should be a short rubber hose connecting this tube with another metal line that goes to the steering box. There are two metal lines threaded into the top of the steering box. The steering box is located at the end of the steering column and is bolted to the drivers side frame rail at the front of the vehicle. You will have to remove the left front tire to access these fittings. The rubber hose will be attached with hose clamps and are prone to leak. To tighten the threaded fittings, you will need a 16mm open end wrench, or preferably a flare nut wrench of the same size.

Are the power steering lines connected to the oil lines somehow? Just before my power steering crapped out, I would top up the pump reservoir only to blow white smoke out the tailpipe all the way home. How...


Hi. Your power steering pump hoses are closed looped. They run from the pump assembly to the reservoir.They do not run to any of your oil lines. Now, with that said, i would recommend to inspect your assembly for possible leaks. This is a high pressure setup that will produce leaks during hose or clamp failure. The reservoir can crack as well. This will cause fluid to leaks on the engine block or exhaust manifold, thus, causing the white smoke or burn off affect. Use the procedure below to inspect for possible loose hoses or compromised pump seals and reservoir issues.



Once you have staged your vehicle in a safe place, open the hood and locate your power steering system on your vehicle. The easiest way is to follow the part of the steering column assembly that goes through the firewall. Follow the components connected to the steering column all the way to the wheel assemblies and hoses connected to the power steering pump and reservoir. Attempt to scrub wet and dirty components around the steering system, using shop rags if the leak source is not readily apparent. Now,start the engine, rotating the steering wheel all the way from left to right several times to increase system pressure in the pump and hoses. Turn off the engine and inspect the system from the engine compartment, using a flashlight preferably. In some cases, you might have to wait one or two days for the leak to reveal itself . Next, check around the power steering pump, for possible cracks. If you find fluid around the pump case, the case is damaged and should be replaced. Some pumps are equipped with internal seals that may be replaced when necessary. Also, look around the reservoir and make sure it is in good condition. A cracked reservoir must be replaced as well.

Now, look around all fittings and hoses. A loose fitting cannot contain the high pressure in the system. Tighten clamps using a Phillips or flathead screwdriver or ratchet and socket, depending on the type of fitting or clamp used in your system. Additionally, check along the hoses for cuts. If possible, run your fingers along the length of the hose to find hidden wet spots. A hose leaking somewhere along the middle will have to be replaced. If the gash is very close to the end of the hose, you might be able to cut off the damaged part and reconnect the hose to the component. You will also need to Check the metal lines connecting the steering gear assembly to other components. A ruptured metal line must be replaced.

Lastly; Inspect completely around the rubber boots located between the ends of the steering gear assembly and the arms linking the assembly to the wheels. If fluid is leaking at either end, then the seals at the ends of the steering gear assembly will need to be replaced. If necessary, raise the front end of the vehicle using a floor jack and support it on jack stands or ramps. Once the vehicle is safely supported, inspect the steering gear assembly more closely to see if it is in good or bad condition . Make sure you check all the ares above for possible leaks or loose connections before replacing the entire pump.

How to change inner tie rod ends?


if fluid is flowing out the bellows, you need to replace the steering rack assembly. There is no fluid in the area of the inner tie rod. The seal is just before the tie rod.

Steering Gear
The power rack and pinion steering gear is serviced as a power steering short rack (3L547). The front wheel spindle tie rods (3280) and tie rod ends (3A130) are serviced individually. -------------------------------------------------------------------------------------------
  • The power rack and pinion steering gear incorporates quick connect fittings for the power steering pressure hose (3A719) and power steering return hose (3A713) that allow the lines to swivel. This is normal and does not indicate loose fittings.
  • If the fittings leak, check to make sure they are tightened to 14-20 Nm (10-14 lb-ft). Do not overtighten.
  • If the leak is not corrected, replace the fitting seals.
