If you drive in extremely hot climates:
It may be necessary to have a Ford authorized dealer decrease the
coolant concentration to 40%.
A coolant concentration of 40% will provide improved overheat
protection. Decreased engine coolant concentrations below 40% will
decrease the corrosion/freeze protection characteristics of the engine
coolant and may cause engine damage.
Vehicles driven year-round in non-extreme climates should use
prediluted engine coolant for optimum cooling system and engine
protection.
Powertrain Limiting and Protection
Note: Driving the vehicle without repairing the engine problem increases
the chance of engine damage. Take your vehicle to an authorized dealer
as soon as possible.
The engine control module (ECU) is equipped with a feature called
powertrain limiting and protection (PTLP). PTLP will help protect the
engine from damage in case the engine is overheating (coolant and/or oil
temperature too hot). PTLP will automatically intervene during normal
engine operation should it determine the engine coolant and/or oil
temperatures are too hot. It does this by gradually reducing the
maximum allowable engine rpm until the engine has cooled sufficiently.
PTLP will automatically reinstate normal engine operation if it
determines the engine temperatures have cooled sufficiently.
During an engine overheating condition, the instrument cluster will
display a message and a chime will sound. The engine may also have
temporarily reduced power and reduced rpm limit during an overheating
condition.
Operating the engine with high engine coolant temperature (coolant
gauge indicator is red) may cause powertrain damage. Stop the vehicle
as soon as safely possible, and let the engine cool off while idling.
