I have a 2007 f150 with the 5.4 in it and today I was driving it and my tempreture gauge randomly shot to cold and check engine light came on. Also can't even find the dam radiator cap due to too much plastic!!!

 

I don't think there is a radiator cap on these trucks. The radiator is filled through the overflow tank. You should have the codes pulled since the engine light came on. Check back once you know what they are so we can help you.

 

Not able to get a code yet. But engine shut off while driving and won't keep running for more than a couple seconds
