Hi there,

The V8s are easier than V6.

The system will bleed up fairly well, but I like to get a powerade bottle or similar to raise the fill point, allows the air to come out while maintaining high coolant level.

There is a tool available for this purpose.

Heater on max hot, fan speed 1, A/C off.

Monitor engine temp, check heater blows hot air, cap on, overflow tank on full mark.

Let engine cool down overnight, check levels in the morning.
