How to Change the Oil on an International TD6 Diesel: Step-by-Step Guide
Changing the oil on your International TD6 diesel isn’t just routine maintenance—it’s a ritual that keeps this classic crawler running strong. Whether you’re a seasoned operator or just getting your hands dirty for the first time, here’s a straightforward, no-nonsense guide to get the job done right.
What You’ll Need
Before you start, gather your supplies. You’ll need:
- The correct oil (check your manual, but 15W-40 diesel oil is a safe bet for most climates)
- A new oil filter
- A drain pan (big enough for about 3 gallons)
- A funnel
- A wrench set
- Rags or shop towels
- Gloves (optional, but your hands will thank you)
Step 1: Warm Up the Engine
Start your TD6 and let it idle for 5-10 minutes. Warm oil flows better and carries more contaminants out with it. Shut the engine off and let it sit for a minute so you don’t burn yourself.
Step 2: Locate the Drain Plug
Crawl under the left side of the engine. The oil pan drain plug is a big bolt at the bottom of the pan. Place your drain pan underneath.
Step 3: Drain the Old Oil
Using your wrench, loosen the drain plug. Be ready—the oil comes out fast and hot. Let it drain completely. This is a good time to check the old oil for metal shavings or milky color (bad news if you see either).
Step 4: Remove and Replace the Oil Filter
The oil filter on a TD6 is usually a canister style, mounted vertically on the right side of the engine.
- Unscrew the center bolt on top of the canister.
- Carefully lift off the lid and pull out the old filter element.
- Clean out the canister with a rag.
- Drop in the new filter element, making sure it’s seated properly.
- Replace the lid and tighten the center bolt.
Step 5: Reinstall the Drain Plug
Once the oil has finished draining, wipe the area clean and reinstall the drain plug. Don’t overtighten—just snug it up.
Step 6: Add Fresh Oil
Remove the oil fill cap on top of the engine. Using your funnel, pour in fresh oil. The TD6 takes about 3 gallons, but always check your dipstick as you go. Add oil slowly, checking the level to avoid overfilling.
Step 7: Check for Leaks and Final Level
Start the engine and let it idle for a minute. Shut it off and check under the machine for leaks—especially around the drain plug and oil filter. Wait a few minutes, then check the oil level again and top off if needed.
Step 8: Clean Up
Dispose of the old oil and filter properly—most auto parts stores will take them. Wipe down any spills, and give yourself a pat on the back.
That’s it! Changing the oil on a TD6 diesel is a simple job that pays off in reliability and peace of mind. Keep a log of your oil changes, and your old iron will keep chugging along for years to come. If you’ve got any tips or stories from the field, drop them in the comments below!
