QwikGlowPro® is designed to be used with the QwikInjector® (QT2510). You will need to connect the QwikInjector® to your manifold. Then pour QwikGlowPro® in to the QwikInjector®. You will then need to connect to the low side of the cooling system first, and connect to the high side second. Finally, you will need to open the manifold valve. The high side pressure will push the QwikGlowPro® through the low side of the system.
