full_jingbang Posted November 12, 2014 Report Share Posted November 12, 2014 I heard that new cars have a system of auto shut vehicle when they overheat. anyone personally experienced if Edge 07 have the same ? recently I had a heating problem, the needle went to 3 quarter but the engine was still running.

akirby Posted November 12, 2014 Report Share Posted November 12, 2014 I thought it did but not positive. If it does then it has to go higher than 3/4 for it to kick in. Ours overheated when one of the fans failed. It was hot enough for the overflow tank to boil over and it did not shut down. Quote Link to comment Share on other sites More sharing options...
omar302 Posted November 12, 2014 Report Share Posted November 12, 2014 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. 2 Quote Link to comment Share on other sites More sharing options...
WWWPerfA_ZN0W Posted November 12, 2014 Report Share Posted November 12, 2014 Pretty cool stuff! Wonder if you could run the alternating cylinder mode under normal conditions as a "fuel economy" measure also. Quote Link to comment Share on other sites More sharing options...
bce Posted November 12, 2014 Report Share Posted November 12, 2014 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. 1 Quote Link to comment Share on other sites More sharing options...
WWWPerfA_ZN0W Posted November 12, 2014 Report Share Posted November 12, 2014 More along the lines of, if you ran a tune, could it done in the tune? Is it available to the tuner to make happen? Quote Link to comment Share on other sites More sharing options...
akirby Posted November 12, 2014 Report Share Posted November 12, 2014 Ford already does some cylinder deactivation. If it was simple enough that a tuner could do it then it would be standard if it actually improved mpg. It's probably way more complicated and not available to a tuner.

I THINK THIS MAY BE THE BEST & CORRECT ANSWER AND ACCORDING TO BOOK.... thank you Quote Link to comment Share on other sites More sharing options...
