The typical drain plug thread size for Ram 1500 Hemi engines is M14 x 1.5 (a 14mm-diameter thread with a 1.5mm pitch).
Across most Ram 1500 Hemi configurations—primarily the 5.7L Hemi and the 6.4L Hemi found in various trims—the M14 x 1.5 drain plug is standard. However, there are occasional year-by-year or special-edition variations. To be certain, consult your owner's manual or inspect the plug you currently have before purchasing replacements.

- 5.7L Hemi installations in Ram 1500 models in many model years

How to verify the exact plug size on your truck
Before you purchase a replacement plug or a magnetic upgrade, confirm the size on your specific vehicle using these steps.
- Check the owner's manual or the Ram/MOPAR service guide for the specified drain plug size and recommended torque.
- If you have access to the current plug, measure its thread diameter with calipers to determine if it is M14 (approx. 14mm) or another size.
- When shopping for an aftermarket plug, search for “M14 x 1.5 drain plug” to ensure compatibility with your Ram 1500 Hemi.
- If in doubt, contact a Ram dealer or a trusted shop with your VIN to confirm the exact specification for your truck.
After confirming the size, follow the manufacturer’s torque specification during installation and replace any washer or seal as required by the drain plug design.
Practical tips for replacement
Tips to ensure a clean and secure oil drain plug replacement:
- Use a magnetic drain plug if possible to help catch metal particles during future changes.
- Inspect or replace any gasket or copper washer associated with the drain plug if your model uses one.
- Do not overtighten; use the recommended torque from the manual to prevent stripping the pan threads.
Following these practices helps prevent leaks and preserves the integrity of the oil pan threads over time.
