Conversion to an all evans colant system is now complete in my 3.3 l 2005 GC.

Both heater cores and radiator should last a long time.

Hey - looks great, but could you expand on what the Evan's coolant sys is? That's a new one on me lol

Around $37/gallon delivered.

Big cost in replacing heater cores in these vans so Evans provides me with option of reducing the pressure being put on the heater core/radiator by 56%. Chep heater cores and radiators just will not stand up to 16 psi for very long. The following benefits also are nice.
