  Q: How to remove and install the distributor cap and distributor rotor on Volvo 740?

  A:

  To fit and take out the distributor cap, remove the negative battery cable than proceed. It might be required to take off the air cleaner housing and hoses in some models. Then, take out retaining screws of distributor cap and lift it at a right angle without incurring damage to the rotor blade. Unscrew and identify sparks plug wires at the cap and where provided, remove screws connecting rotor to distributor and while doing so, remember the position of the rotor in its housing to place it back. Check the cap and the rotor regarding damage and replace where necessary. To install it, reattach the rotor at the distributor shaft and apply the screw at the back (the retaining bolt, when it is there). Next, you will need to install the distributor cap and screw it in with the retention screws and then reconnect the spark plug wires in the appropriate positions. In case the air cleaner housing is taken out, its placed back, the vehicle started to make sure it was running properly and then the negative battery cable was attached in the end. Once the cap and rotor are removed, wash all the parts thoroughly using soap and water and where possible dry it using compressed air or even a soft cloth that is clean to touch, without leaving the lint or any moisture in them. After cleaning, check cracks, carbon tracks, burns, or other damage, make sure the carbon button on the cap remains and insure that the terminals are free of dirt or corrosion. Carefully inspect the rotor part and the spring to determine the extent of damage and change the parts exhibiting any form of wear or damages.

  Q: How to remove the spark plug HT lead cover and distributor cap on Volvo S70?

  A:

  Note that the following instructions do not apply for models with the Emotronic ME7 system. To remove the spark plug HT lead cover, undo the screws and pull it from the center of the cylinder head. Pull the HT leads off the spark plugs and release them from the retaining clips, marking them if needed so they are not confused when reinstalling them. Next, undo the 3 screws which hold the distributor cap; these are captive screws so do not try to remove them completely. If necessary, access the air cleaner by releasing the clips and moving the air cleaner lid aside. Lift the distributor cap and HT leads off together being careful not to remove the HT leads from the distributor cap unless absolutely necessary; if it is necessary to remove the cap and the HT leads, make sure that both the distributor cap and the HT leads are marked to maintain the order of firing. After that, remove the flash shield, and mark the position of the rotor arm with respect to the distributor to reinstall. Alternatively, if a new rotor arm is being fitted, set the engine to TDC on No 1 cylinder so that the rotor arm is pointing to the notch mark on the distributor body. Finally, undo the three screws and take the rotor arm off. For reinstallation, do the opposite order of removal and make sure that the HT leads are held in their clips and not trapped when putting on the cover.
