lowkooler high flow pump 1745 for the Jeep and AMC engine has a CNC machined billet impeller designed with an increased vane count and a reduced impeller clearance to achieve greater flow rates, higher block pressure. A Type II Class II military grade anodize surface coating protects against corrosive fluids. 

We developed this hi flow pump because Jeeps tend to overheat in traffic and on the trail. Tight engine space and limited airflow plague the cooling system but it has been proven time and time again that reducing the cycle time between the heat source and the heat sink drops engine temperatures for slow speed rock crawling and stop and go traffic.

From 0-3,300 RPM…Nothing Beats a FlowKooler!

Good for sensitive skin
Style: Updated Formula
It actually helps my skin. I had curology before this and still had breakouts around my lips and nose. After trading to this, it has calmed down a lot. No bumps or pimples. This package is smaller samples to test out to see if it's good for you and your skin. Its really good for sensitive skin.
