Metric vs SAE

[frozenrice]

Have the domestic makers switched over to metric in their modern vehicles? The last time I wrenched on a domestic vehicle, domestics were pretty much all SAE nut/bolt sizes. I’ve always owned imports so all my sockets and wrenches are metric. I’m going to be helping someone with their Ford Edge but just realized I might not have the right tools.

Been metric for a LONG time. You'll be fine.

Ford and GM seem to have been using metric since the late 00s as far as I can tell.

Well before that.

Yep. They switched in the 80s.

Hmmm.... I was pretty sure my 86 trans am was imperial, and I thought the 4th gens were too? I was surprised that my '11 Camaro was metric so I figured it was phased in during the interim. The Fords I have been dissecting for my kit car project are definitely some ungodly combination..

It tended to vary from model to model. Dodges had an era of ~15 years of SAE drivetrains in metric chassis, no point in updating the drivetrains to metric until you hit the next engine generation.
