Need Torque Specs for:

• Oil Cooler Housing (3 Bolts)
• Oil Cooler Line Adapter Bolt (1 Bolt)
• AN Lines (4 fittings)

Thanks,

Just call or email Fred at ER and he'll fix you up - or if he's not there, one of their techs can help. Those AN fittings are aluminum, so I'm not sure if there's a torque spec for them that's any different than in other applications (aircraft, etc.). I believe they're AN-10, so you might do a little research and find that info on the web. The specs for the housing pieces should be available online as well.

One bit of advice - make sure those oil lines are tie-wrapped so as not to kink or rub up against anything (like the intercooler clamp). Ask me how I know this.

I emailed the vendor I bought it from and also ER. Vendor didn't know, ER said "hand tight." I prefer to be a precise, so I asked my mechanic. I'll post the correct answer when a get a reply.
