Do I need any special tools or adapters to install this radiator?

Factory mounting points align with OEM brackets—standard hand tools and a drain pan are all you need. Disconnect your coolant hoses, unbolt the old unit, and seat the new one at the same mounting locations.

Should I flush the cooling system before installation?

Yes. Drain the old coolant completely, flush the block and hoses with clean water, then fill with fresh coolant. This prevents sediment from settling in the new radiator and extends its life.

What coolant type should I use?

Refer to your Mack service manual for the correct coolant spec—typically heavy-duty conventional or extended-life formulas. Do not mix types; always start fresh.
