Question type: Maintenance & Repair

1999 F250 Super Duty , 4X4 , 5.3L engine , V-8 We are replacing the EGR (Early Gas Release) valve on our F250
Super Duty. There is a nut on the main part of the valve, that we do not know the size of. I believe it is an inch but
wondered if you have a definite size.

EGR means Exhaust Gas Recirculation. Doesn't it? Or correct me if I am wrong on that engine

'sokay.....I meant I wish I knew what size that big nut on the steel line was. The ones that hold it on look like maybe 13 mm or 1/2"

DavidH25 The nut on the bottom right of the photo you have there. It has to be an open ended wrench and 21mm is too small.
