You can Select Your Vehicle to check if 4850377 fits your vehicle.

Start by removing the battery hold-down clamp. Unscrew the hold-down bolt and remove the clamp. Carefully lift out the heavy battery.

Disconnect the negative cable first, then the positive cable. Remove the battery thermo-wrap, hold-down clamp, and lift out the battery. Replace it with a battery of identical specifications. When removing the battery tray, disconnect the hose from the vacuum reservoir, remove the mounting bolt and nuts, and lift up the tray while disconnecting the electrical connector from the battery temperature sensor. Wash the tray and reinstall it following the reverse of the removal process.

If the battery tray is damaged, it should be repaired or replaced.

A routine preventive maintenance program for the battery is essential for quick and reliable starts.

Disconnect the negative battery cable and visually inspect the battery's state of charge using the indicator eye (if equipped). Charge the battery or add distilled water if needed. Use a hydrometer to check the specific gravity of the electrolyte in each cell. Perform an open circuit voltage test using a digital voltmeter, ensuring the battery voltage is above 12.5 volts. Use a battery load tester to evaluate the battery's ability to handle heavy amperage draw during startup and accessories operation. Cold temperatures may slightly affect the minimum voltage requirements. To test for battery drain, disconnect all accessories and check the current drain using a digital ammeter. Normal drain is around 100 milliamps or less, while excessive drain can cause battery discharge.

When servicing the battery, precautions should be taken such as turning off the engine and all accessories and disconnecting the cable from the negative terminal.

Ensure it matches the dimensions, amperage rating, and cold cranking rating of the original battery.

Connect the positive (+) battery cable first, then the negative (-) battery cable second.

If corrosion is present on the cables and terminals, clean them and apply petroleum jelly or grease to minimize future corrosion.
