Volvo Coupes/Sedans/Wagons 1970-1989 Repair Guide
REMOVAL & INSTALLATION
Remove the positive and negative cables from their terminals on the top of the battery. If the cables remain stuck to the terminals after loosening the cable clamps, use a puller to free them. Do not try to pry the cables off the terminals; damage to the battery case and/or the terminals may result.
Remove the battery hold-down bar and lift out the battery. Keep the battery upright to avoid spilling acidic electrolyte.
Clean the battery case and support shelf with a brush and rinse with clean, lukewarm water. Remove any deposits from the terminals and cable ends with a wire brush or battery terminal tool.
Replace the battery on its support shelf and install the hold-down bar.
Install the cables in their proper terminals and tighten the clamps. Coat the exposed metal of the cables and terminals with petroleum jelly to prevent corrosion.
