2019 Ram 4500 / 5500 Cab — 6.4L

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2019 4500 / 5500 Cab 6.4L.

Engine 6.4L

Built on the robust DP chassis and motivated by a 6.4L engine, the 2019 Ram 4500 and 5500 Cab models are positioned as uncompromising commercial workhorses. However, researchers should note a striking disparity in the truck's regulatory and ownership history, highlighted by a significant 10 recalls contrasted against just six total owner complaints. With the engine representing the top complaint area, this model year sits at a peculiar crossroads in the vehicle's reliability timeline, where widespread manufacturer interventions address potential systemic failures even as the most frequent owner-reported issues remain concentrated under the hood.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter every 8,000 mi; coolant every 8,000 mi. The big-interval services (every 8,000 mi for coolant, and the transmission fluid) are the ones owners most often skip — on a lower-mileage example, assume the original fluids are still in it and check them first.

These are tallies of what owners actually reported to the federal government, not an editorial score — and higher-selling models naturally rack up more reports.
