I HAVE 2005 6.0 L. IT HAS 180000 MILES. THE UNIT IS NOT WANTING TO START TO WELL WHEN COLD. I CHECKED ON GLOW PLUG REPLACEMENT AND ABOUT HAD A HEART ATTACK . I DIDN'T HAVE A PROBLEM WITH THE PRICE OF PARTS BUT THE LABOR WAS CRAZY. HOW LONG OR HOW MANY HOURS DOES IT CALL FOR TO REPLACE GLOW PLUGS? IT IS A F-350.

 

Okay, first of all. Shut off caps lock.

Secondly, check for codes. I doubt you have a glow plug problem. If you do, you will have codes.

 

If it was a Ford dealership, chances are they were using book rates. Why didn't you ask how long of a job were the quoting the labor on?
