Under Engine Cover - Bolt Size ??

Post by Bluespanner » Mon Jun 18, 2018 10:32 am

Having removed the under engine cover to do maintenance I've mislaid the bolts that secure it to the vehicle. Tried AVA they don't stock them and getting them from Mazda will cost a arm & leg. Anyone know the bolt size/spec for the engine cover.. Cheers in advance

I’ve not removed the undercover from the engine on the Bongo yet, but most of my other vehicles have used a plastic rivit that are cheap on Amazon. Plus they are reusable. Maybe they’d work for you. Otherwise it’s Bongo breakers for some used ones 8)

They're 6mm threads with 10mm heads.

Go to ebay and search for "M6 flanged stainless"

You will get loads of vendors, I've used this lot before:-

Luckily, I've just taken mine off so I measured one and it's 15mm long. Closest size on there is 16mm which will work fine.

The ones on the V6 are a bit longer than the diesels, I'm guessing its about about 1". :)
