OVERHEAT "Auto-shut"

Recommended Posts

From the Owners Manual (2007) quoted below, notice the following:

 

"coolant temperature gauge will move to the red (hot)", so it seems neither of you have reached the level that causes the Fail-Safe Cooling to kick in.

 

Also, from this part "If the engine coolant supply is depleted", it indicates that the temperature reading is NOT the coolant fluid's temperature, rather it is the actual temperature of the Engine Head or Block.

 

What you should know about fail-safe cooling

If the engine coolant supply is depleted, this feature allows the vehicle to

be driven temporarily before incremental component damage is incurred.

The “fail-safe” distance depends on ambient temperatures, vehicle load

and terrain.

How fail-safe cooling works

If the engine begins to overheat:

• The engine coolant temperature gauge will move to the red (hot)

area.

• The symbol will illuminate.

If the engine reaches a preset over-temperature condition, the engine

will automatically switch to alternating cylinder operation. Each disabled

cylinder acts as an air pump and cools the engine.

When this occurs the vehicle will still operate. However:

• The engine power will be limited.

• The air conditioning system will be disabled.

Continued operation will increase the engine temperature:

• The engine will completely shut down.

• Steering and braking effort will increase.

Once the engine temperature cools, the engine can be re-started. Take

your vehicle to an authorized dealer as soon as possible to minimize

engine damage.

Pretty cool stuff! Wonder if you could run the alternating cylinder mode under normal conditions as a "fuel economy" measure also.

 

I'm sure it could. I know that other engines do it. http://en.wikipedia.org/wiki/Variable_displacement.

 

Now, if you wanted to know if YOU could -- that's a different question. I would doubt that is it something the average person could make there car do. Lots of changes in lots of different places.

I THINK THIS MAY BE THE BEST & CORRECT ANSWER AND ACCORDING TO BOOK....

 

thank you
