What should I do before the first start?

Fit a new oil filter, fill with the correct oil and refill the coolant. On turbo engines, fill the turbo oil feed with clean oil.

Turn the engine over without fuel or ignition until the oil pressure light goes out. This brings oil to every bearing before the engine runs.

Check all hoses, clips and electrical plugs, then start the engine and let it idle while you look for leaks.

Bleed the cooling system and top up as the air comes out.
