Coolers
EGR cooler crackingCommon
You’ll notice: coolant loss, white smoke, overheating.
Why: The EGR cooler can crack and let coolant into the intake. Ram recalled 2014–2019 trucks (19V-757).
Our fix: We check recall status and replace the cooler when needed.
Oil cooler failureCommon
You’ll notice: oil in the coolant or coolant in the oil.
Why: The engine’s oil cooler can fail and mix fluids, which hurts the bearings.
Our fix: We replace the cooler and flush the systems.
Engine
Crank sensor tone wheelCommon
You’ll notice: stalling while driving.
Why: The crankshaft sensor tone wheel can come apart. Ram recalled some trucks.
Our fix: We check recall status and repair it.
Main and rod bearing failureHigh miles
You’ll notice: knocking, low oil pressure.
Why: Bearing failures have been reported, often tied to oil condition.
Our fix: We diagnose it early and repair or replace the engine when needed.
Fuel system
High-pressure fuel pumpCommon
You’ll notice: stalling, no-start, metal in the filter.
Why: Ram issued fuel pump recalls for 2014–2023 trucks.
Our fix: We check recall status and repair the fuel system.

MAINTENANCE SCHEDULE
3.0 EcoDiesel service intervals.
These are Ram’s factory intervals from the owner’s manual schedule. The factory “severe” column covers towing, dusty roads, short trips and long idling, which describes most working trucks in Southern Arizona. Our recommendation follows the severe schedule, with oil every 5,000 miles and fuel filters every 10,000.
| Service | Factory, normal use | Factory, severe use | Our recommendation |
|---|---|---|---|
| Engine oil & filter | Oil change indicator, never over 10,000 mi / 12 months | 8,000 mi / 6 months on biodiesel over B5 | Every 5,000 mi |
| Fuel filter & water separator | 30,000 mi / 36 months | 20,000 mi / 24 months on biodiesel over B5 | Every 10,000 mi |
| Engine air filter | 30,000 mi / 36 months | Inspect at every oil change | Inspect at every oil change |
| Coolant | 150,000 mi / 10 years | Same | 150,000 mi / 10 years |
| Serpentine belt | 100,000 mi / 10 years | Inspect at oil changes | Inspect at oil changes |
| 8-speed transmission fluid | No interval (factory says lifetime) | Same | No interval (factory says lifetime) |
| Transfer case fluid | 120,000 mi / 12 years | 60,000 mi / 6 years (towing or frequent 4WD) | 60,000 mi / 6 years (towing or frequent 4WD) |
| Front axle fluid | Not set by the factory | 20,000 mi / 24 months (towing or off-road) | 20,000 mi / 24 months (towing or off-road) |
Always go by your owner’s manual for your exact truck. Factory figures are maximums, and the dash service reminder comes first when it shows sooner.
