2005 6.0
Fit my 2005 F250 6.0 like a glove. Feels MUCH tighter than the last one that I suspect PO had an aftermarket one on because this one came in a sealed OEM package from Ford. So now I suspect my degas bottle in general is aftermarket which explains a lot. I heard hissing from the last cap one day so I tightened it a few more clicks and it seemed to stop the leak. However, these are very reasonably priced and it’s not worth the risk to keep the possibly faulty old one on. One less thing to worry about. Now there are only 9,337 other problems left instead of 9,338.

Perfect OEM coolant reservoir cap. No leaks, very good build quality. It's always good to have an extra with you. Worked better then the AutoZone & Carquest aftermarket caps. Perfect for my 6.0L diesel after a top end overhaul!

se lo cambie a mi Mustang por sospecha, vi que no era el problema pero siendo piezas motorcraft no hay de que dudar de su calidad.
