Based on the information provided, it's possible that the issue with your 2008 Acadia is related to the cooling fans not working, the overheating, and the subsequent no-crank, no-start condition. Let's try to break down the possible causes:
Cooling Fans Not Working: If the cooling fans are not functioning correctly, it can lead to engine overheating. The cooling fans are responsible for cooling the radiator and the engine when the temperature rises above a certain threshold. The fans should turn on automatically when the engine gets hot.
No-Crank, No-Start Condition: The no-crank, no-start issue can be caused by various factors, some of which may be related to the previous overheating problem:
Weak Battery: Insufficient power from a weak battery can prevent the starter from cranking the engine. If the engine overheated, it's possible that excessive heat could have affected the battery's performance.
Starter Motor Failure: The starter motor may have failed, preventing it from turning the engine over.
Faulty Ignition Switch: A faulty ignition switch can disrupt the electrical circuit needed to engage the starter.
Overheating Damage: In severe cases of overheating, engine damage can occur, leading to a no-start condition.
Here are some steps to help diagnose the issue:
Check the Battery: Test the battery with a multimeter to ensure it has sufficient voltage. If the voltage is low, recharge or replace the battery as needed.
Inspect the Starter Motor: Listen for any clicking sounds when turning the key to the "Start" position. If you hear clicking but the engine doesn't crank, it may indicate a faulty starter motor.
Test the Ignition Switch: Check if there is power at the starter solenoid when the key is turned to the "Start" position. If there is no power, the ignition switch may be faulty.
Check for Engine Damage: If the engine experienced severe overheating, there may be internal damage that is preventing it from starting. In such cases, a professional inspection is necessary.
