Evans prep fluid is designed to assist with the conversion to Evans waterless coolant. Prep fluid will seek out any trace amounts of water remaining in the system when it cannot be completely drained out. It is to be used a flush only, not as a stand alone coolant. It is not necessary to completely fill the system with Prep Fluid, only enough to circulate through the system.
Usually ships in 2 to 3 days. Ships UPS Ground only.
