How to deal with high water temperature in an old Buick GL8?

[KarterLee]

After parking the car, you need to check whether the cause of the high water temperature is low production capacity. First, open the engine hood to see if the coolant level in the auxiliary tank is normal. If the coolant level is below the min line, it means the coolant is insufficient. Keep the engine idling for a while, and turn on the air conditioner to the maximum heating position to help dissipate heat. At the same time, open the engine hood to help dissipate heat. Wait until the coolant temperature drops to the normal value before turning off the engine.
