Q. WHAT BENEFITS DOES THE FILL-FOR-LIFE PROGRAM PROVIDE?
A. There are several important benefits:

Most of the standard factory-fill antifreeze in today’s trucks meet the TMC RP-329 specifications, so you don’t have to change your new coolant or pay extra for a factory option.

Your program will be compatible with other, older technology antifreeze, so you can use the new antifreeze in your older cars and trucks or buy antifreeze on the road in a pinch without creating a cooling system catastrophe.

If your system becomes diluted or contaminated you can fix it with your RP-329 antifreeze and/or Pencool 3000. You don’t have to throw the contaminated coolant away, and you don’t lose the extended service benefit. You can easily test your system with Penray 2-Way Test Strips or inexpensive laboratory analysis to be sure it is in good shape.
