Engine Temperatures

Try to find an oem Mopar fan. Moves a lot more air than the aftermarket replacements. The stock wiring should work if it’s all in good shape but it was always marginal at best. You need a solid 30amps for the fan to run at full rpm and therefore get the full cfm needed. Many will swap on all e fans and wire them up using a relay to the battery. But many fans’ CFM are rated at alternator voltage which will typically be around 13.8-14v.
