For the 2.5L 4-cylinder engine:
- A fully charged 12-volt battery (around 12.6 volts) is generally sufficient to start the engine under normal conditions.
- When the battery voltage drops below approximately 11.5 volts, the engine may struggle to start or fail to crank altogether.
For the 3.5L V6 engine:
- A fully charged 12-volt battery is also recommended, but due to the larger engine size, the voltage requirement may be slightly higher.
- Starting issues can arise when the battery voltage falls below 12 volts for the V6 engine.
It's worth noting that factors like extreme weather conditions (cold temperatures or excessive heat), electrical load (accessories or devices consuming power), and battery age or condition can influence the starting voltage requirements.
To ensure trouble-free starting, maintaining a healthy battery and proper charging system is crucial. If you experience repeated starting problems, it's advisable to have your vehicle's battery and charging system checked by a qualified mechanic.
