Acura Coupes and Sedans 1986-1993 Repair Guide



See Figures 1, 2, 3 and 4

All Acura models are equipped with maintenance free batteries. These require no addition of electrolyte, only periodic checks. All Acura batteries are equipped with a test indicator window on the top of the battery. This can be used to check the state of charge; BLUE indicates a complete charge, WHITE indicates that charging is needed.


Once a year, the battery terminals and the cable clamps should be cleaned. Loosen the clamps and remove the cables, negative cable first. On batteries with posts on top, the use of a puller specially made for this purpose is recommended. These are inexpensive, and available in auto parts stores. Side terminal battery cables are secured with a bolt.

Clean the cable clamps and the battery terminal with a wire brush, until all corrosion, grease, etc., is removed and the metal is shiny. It is especially important to clean the inside of the clamp thoroughly, since a small deposit of foreign material or oxidation there will prevent a sound electrical connection and inhibit either starting or charging. Special tools are available for cleaning these parts, one type for conventional batteries and another type for side terminal batteries.

Before installing the cables, loosen the battery hold down clamp or strap, remove the battery and check the battery tray. Clear it of any debris, and check it for soundness. Rust should be wire brushed away, and the metal given a coat of anti-rust paint. Replace the battery and tighten the hold down clamp or strap securely, but be careful not to over tighten, which will crack the battery case.

After the clamps and terminals are clean, reinstall the cables, negative cable last; do not hammer on the clamps to install. Tighten the clamps securely, but do not distort them. Give the clamps and terminals a thin external coat of grease after installation, to retard corrosion.

Check the cables at the same time that the terminals are cleaned. If the cable insulation is cracked or broken, or if the ends are frayed, the cable should be replaced with a new cable of the same length and gauge.

Keep flame or sparks away from the battery; it gives off explosive hydrogen gas. Battery electrolyte contains sulfuric acid. If you should splash any on your skin or in your eyes, flush the affected area with plenty of clear water. If it lands in your eyes, get medical help immediately.

Acuras equipped with a manual transaxle can be push-started. Make sure that the bumpers match as otherwise a damaged bumper and/or fender could result from push-starting. To push-start your Acura, turn the ignition switch ON , push the clutch in, and select 2nd or 3rd gear. As the vehicle picks up speed (10-15 mph), slowly release the clutch pedal until the engine fires.

If your vehicle is equipped with an automatic transaxle, it cannot be push-started. Shifting the transaxle into gear has absolutely no effect until the transmission oil pump, driven by the engine, begins to run.

To jump start the vehicle:

  1. Bring the vehicles close to each other and open the hoods.
  3. Pull back any covers from the battery terminals.
  5. Turn off all accessories in both cars and set the parking brake.
  7. Identify the positive and negative terminals of each battery and connect the jumper cables. The cables should be connected to the positive terminal of the dead battery first then to the positive terminal of the other vehicle.
  9. Connect the negative jumper cable to the battery of the assisting car then the other end of the negative jumper cable to a good ground on the dead cars engine or frame.
  11. Start the engine in the assisting vehicle and run the engine at fast idle. Try to start the dead car.
  13. If the dead car does not start after a few tries, there may be a larger problem. Disconnect the jumper cables in reverse order.
