2018 5.7 Hemi water pump replacement

Order a factory unit online through one of the Mopar parts dealers that sell at a discount. Give your vin number to get correct parts. I get my G08 coolant from NAPA and dilute with distilled water 50% . Might as well check your belt, idler pulley bearing and replace the cap,hose, clamps and thermostat at the same time. Now is the time since you will have it apart anyway.
