GR Yaris Under tray bolt torque

[adz87kc]

Does anyone know the torque settings for the undertray bolts?

They're coming off to apply underseal.

I doubt very much there is a published figure - they'll just have to be tight. If it troubles you, add a bit of Locktite

I'm surprised at that.
I'm used to Nissan detailing every single bolt setting - the GTR workshop manual is phenomenal. I expected Toyota to be the same.
For reference the GTR undertray bolts: M6 9nm and M8 28nm.

Don't suppose you know the bolt material, I guess carbon steel?

Problem with Loctite is if the heads of the bolts rust to oblivion as Japanese cars do, its extra difficult to retrieve what's left in the car. Even if you use the low yield purple stuff let alone blue or green.
