2018 Ram 1500 Factory Maintenance Schedule

Quick reference

Maintaining your 2018 Ram 1500 according to the factory schedule is crucial for its longevity, performance, and retaining its resale value. This guide provides a comprehensive overview of the recommended maintenance intervals, drawing directly from the manufacturer's specifications. Adhering to these guidelines helps prevent costly repairs down the line and ensures your truck performs reliably for years to come.

Severe-duty schedule

Ram understands that not all trucks lead an easy life. If your 2018 Ram 1500 falls into any of the categories below, a more frequent severe-duty maintenance schedule is recommended. This primarily impacts engine oil and filter changes, but other components may also benefit from closer attention.

Conditions for severe duty include:

• Towing or hauling heavy loads frequently: The added stress on the engine and transmission necessitates more frequent fluid changes.
• Driving in dusty or off-road conditions: Increased exposure to dirt and debris will quickly clog air filters and contaminate fluids.
• Frequent short trips (under 5 miles) in extreme cold: The engine doesn't reach optimal operating temperature, leading to moisture and sludge buildup.
• Extensive idling or stop-and-go driving: Similar to short trips, this prevents the engine from fully warming up and can accelerate fluid degradation.
• Driving in extremely hot conditions: High temperatures can break down fluids more quickly.

Key severe-duty adjustments:

• Engine Oil and Filter: Change every 4,000 miles or 6 months, whichever comes first.
• Air Filters (Engine and Cabin): Inspect more frequently and replace as needed, potentially every 15,000 miles or annually, depending on conditions.
• Differential and Transfer Case Fluids: Consider changing every 20,000-30,000 miles if frequently towing or off-roading.
• Transmission Fluid: For severe service, changing the transmission fluid and filter every 60,000 miles is highly recommended, sometimes even earlier if under extreme stress.

Always consult your owner's manual for the most precise severe-duty recommendations tailored to your specific vehicle configuration and usage.

Known issues by mileage

While the 2018 Ram 1500 is generally a reliable truck, certain issues tend to emerge around specific mileage points. Being aware of these can help you proactively address potential problems.

• 50,000 - 80,000 miles:

  • Uconnect System Glitches: Owners have reported touchscreen freezing, navigation issues, or Bluetooth connectivity problems. Often, a software update from the dealership can resolve these.
  • Exhaust Manifold Bolts (HEMI): Broken exhaust manifold bolts, particularly on the HEMI engine, are a common issue leading to ticking noises, especially on cold starts. This is a known design flaw and can be an expensive repair.
  • Rear Air Suspension Leaks: If equipped with air suspension, leaks in the airbags or lines can start to appear, leading to the truck sagging, especially overnight.

• 80,000 - 120,000 miles:

  • Transmission Shifting Issues: Some owners report harsh shifting or delayed engagement, particularly with the 8-speed automatic transmission. This can sometimes be resolved with a software reflash or fluid change, but in more severe cases, could indicate internal wear.
  • Water Pump Failure (HEMI and Pentastar): Water pump leaks or failures can occur, leading to overheating if not addressed promptly. Listen for squealing noises or check for coolant puddles.
  • Front End Suspension Components: Ball joints, tie rod ends, and wheel bearings may start to show wear, especially if the truck has seen heavy use or off-roading. Listen for clunking noises over bumps or feel for looseness in the steering.

• 120,000+ miles:

  • HEMI Camshaft and Lifter Failure: This is a more serious and well-documented issue where the camshaft lobes and lifters wear prematurely, leading to a loud ticking noise, misfires, and reduced engine performance. This is a very costly repair.
  • Electrical Gremlins: As trucks age, wiring and sensor connections can degrade, leading to various electrical issues, from intermittent warning lights to power accessory malfunctions.

Regular maintenance can help mitigate some of these issues, but it's wise to be vigilant and address any symptoms promptly.

Estimated cost per service

Maintenance costs for a 2018 Ram 1500 can vary significantly based on your location, the shop you choose (dealership vs. independent), and whether you use OEM or aftermarket parts. Here's a general estimate for common services:

• Oil and Filter Change: $60 - $120 (depends on conventional vs. synthetic oil)
• Tire Rotation: $20 - $40 (often included with new tire purchases or oil changes)
• Cabin Air Filter Replacement: $40 - $80
• Engine Air Filter Replacement: $50 - $100
• Spark Plug Replacement:
  • V6: $250 - $400
  • V8 HEMI: $350 - $600 (due to plug count and accessibility)
• Brake Fluid Flush: $100 - $180
• Coolant Flush: $150 - $300
• Transmission Fluid and Filter Change: $300 - $600 (depends on 6-speed vs. 8-speed and 2WD vs. 4WD)
• Differential Service (Front or Rear): $150 - $250 per axle
• Transfer Case Service: $100 - $200
• Accessory Belt Replacement: $120 - $250

These are estimates, and getting quotes from multiple reputable shops is always recommended.

What you can DIY vs shop

Many maintenance tasks on your 2018 Ram 1500 can be performed by a competent DIYer, saving you money. However, some services are best left to professionals with specialized tools and experience.

Easily DIYable:

• Oil and Filter Change: Requires basic tools, a drain pan, and a torque wrench. A good way to save money and get familiar with your truck.
• Tire Rotation: If you have a jack, jack stands, and a torque wrench, this is straightforward.
• Cabin Air Filter Replacement: Usually located behind the glove box, requiring no tools or very simple ones.
• Engine Air Filter Replacement: Typically involves unclipping or unscrewing a few fasteners on the airbox.
• Wiper Blade Replacement: A very simple and quick task.
• Checking Fluid Levels: Regularly checking oil, coolant, brake fluid, and power steering fluid is essential and easy to do.

Best Left to the Shop:

• Transmission Fluid and Filter Change: Often requires specific procedures and tools to ensure proper fluid levels and temperatures, especially with modern automatic transmissions.
• Brake Fluid Flush: Improper bleeding can lead to spongy brakes. A shop has the right equipment for a thorough flush.
• Coolant Flush: Proper disposal of old coolant is crucial, and shops often have vacuum fill tools to prevent air pockets.
• Spark Plug Replacement (especially on HEMI): While technically DIYable, the HEMI has 16 plugs, and some are difficult to access, increasing the risk of cross-threading or breaking a plug. Requires precise torque.
• Differential and Transfer Case Service: Involves specific fluid types, proper draining, and refilling procedures to ensure correct levels.
• Timing Chain Inspection/Replacement: The 2018 Ram 1500 uses a timing chain, which is designed to last the life of the engine. Inspection typically only occurs if noise is present, requiring specialized tools and expertise to access and diagnose. This is definitely a shop job.
• Accessory Belt Replacement: While possible for a DIYer, it can be tricky to route correctly and ensure proper tension without the right tools.

When in doubt, always consult your owner's manual for detailed instructions or err on the side of caution and take your truck to a qualified technician.
