ac bypass
 

looking to bypass my AC compressor on my 08 f150 5.4L

I can't find anyone who makes a bypass pulley kit for a 2008 5.4. Why do you want to bypass it?

This *MIGHT* work, read all the comments on the YouTube page:

The reason there is no kit, is because you only need a shorter belt, according to these diagrams:

I'd rather suspect you'll need a different tensioner, one that pushes the opposite direction as does the stock one with A/C and with a grooved pulley.

Manual, do those diagrams apply to a 5.4 3 valve in 2004+?

From what I can tell yes. There's not a whole lot of info out there about doing this on the 3v.

AC took a dump and not looking to fix it till the spring. Looking for temporary fix till then. The belt in that video says it is a 78.5 belt. I could not get a 79 on, but I did not try loosening the alternator as stated in the comments. Ill give that a try and see.

Tensioner
 

Where can you find a tensioner that pulls in the other direction? Because the part numbers look the same but its definitely not right?

6B209 is only part of the whole part number.

It looks like the tensioner for vehicles without A/C is Motorcraft BT65 (Ford 2L3Z6B209CA), but could only find the belt for A/C equipped vehicles. Good luck.
