Fluid Capacities & Specifications
| System | Description | Capacity (qt/gal) | Specification |
|---|---|---|---|
| Engine Oil | |||
| OM612 (2002–2003) | With filter change | ~6.9 qt | MB 229.5 5W-40 |
| OM612 (2002–2003) | Without filter change | ~6.3 qt | MB 229.5 5W-40 |
| OM647 (2004–2006) | With filter change | ~7.4 qt | MB 229.5 5W-40 |
| OM647 (2004–2006) | Without filter change | ~6.9 qt | MB 229.5 5W-40 |
| Engine Coolant | |||
| All models | Total system fill | ~12.7 qt | MB 325.0 Blue silicate |
|
Mix 50/50 with distilled water. Never mix coolant types; flush completely before switching. Zerex G-48 meets MB 325.0 and is the closest match to the factory spec. Zerex G-05 (HOAT) is widely used by the T1N community and is compatible, but is technically a Ford/Chrysler specification, not the official Mercedes type. |
|||
| Automatic Transmission (NAG1 / 722.6 / 5G-Tronic) | |||
| All models | Service refill (pan + filter) | ~5.3 qt | MB 236.12 |
| All models | Full overhaul / dry fill | ~9.0 qt | MB 236.14 |
| Dry fill varies with cooler type, line length, and auxiliary cooler presence. Always check level at operating temperature. | |||
| Rear Axle Differential | |||
| All models | 8.5" ring gear (standard) | ~2.0 qt | GL-5 75W-90 |
| Fill to the bottom of the fill hole. Confirm LSD compatibility if equipped with limited-slip differential. | |||
| Brake Fluid | |||
| All models | System capacity (incl. ABS) | ~1.0 qt | DOT 4 MB 331.0 |
| Replace every 2 years regardless of mileage. Brake fluid absorbs moisture which lowers boiling point. Bleed all four corners plus ABS module. | |||
| Fuel Tank | |||
| All models | Main tank (nominal) | ~26.4 gal | ULSD Diesel |
| All models | Reserve (light to empty) | ~2.8 gal | |
| Use Ultra Low Sulfur Diesel (ULSD, 15 ppm max). See our Diesel Fuel 101 guide for details. | |||
| Power Steering | |||
| All models | System capacity (approx.) | ~1.1 qt | MB 236.3 CHF-11S |
| Exact capacity varies by steering gear and hose routing. Use Pentosin CHF-11S or MB 236.3 equivalent. Bleed by turning lock-to-lock with engine off before starting. | |||
| Windshield Washer | |||
| All models | Reservoir capacity | ~1.6 gal | All-season washer fluid |
Drain & Fill Plug Torque Specifications
Always use a calibrated torque wrench when reinstalling drain plugs and fill plugs. Over-torquing can crack pans or strip threads; under-torquing causes leaks.
| Fastener | Torque (ft·lbs) | Notes |
|---|---|---|
| Engine oil drain plug | 18.4 ft·lbs | Replace copper crush washer at each oil change |
| Oil filter housing cap | 18.4 ft·lbs | Lubricate O-ring with fresh oil before reinstalling |
| Transmission pan bolts (NAG1) | 5.9 ft·lbs | Tighten in a cross/star pattern. Do not overtighten; pan warps easily |
| Transmission fill tube bolt | 5.9 ft·lbs | Check for cracks in the fill tube O-ring |
| Rear differential fill plug | 44.3 ft·lbs | Fill to bottom of fill hole before reinstalling |
| Rear differential drain plug | 44.3 ft·lbs | Clean magnetic drain plug before reinstalling |
| Brake bleeder screws | 7.4 ft·lbs | Snug only; overtightening cracks caliper |
Engine Oil Selection by Climate
Cold Climate
Below 32°F / frequent cold starts
0W-40 Synthetic
Better cold-flow protection
Moderate Climate
Most North American / European regions
5W-40 Synthetic
Best all-around choice
Hot Climate
Sustained temps above 95°F
5W-40 or 5W-50 Synthetic
Better thermal stability
All oils must meet MB 229.5 specification (or newer 229.51/229.52). Popular brands: MOTUL 8100 X-CESS, Liqui Moly Top Tec 4200, Shell Rotella T6.
Fluid Maintenance Tips
Use a Fluid Extractor
A vacuum oil extractor allows mess-free oil and ATF changes through the dipstick tube, with no need to crawl under the van or remove the drain plug.
Don't Mix Coolants
Flush thoroughly before switching types. Zerex G-48 (MB 325.0) is the factory-correct choice. Zerex G-05 is a popular community alternative. Mix 50/50 with distilled water only.
Transmission Service
Use MOTUL Multi ATF or MB 236.12+ fluid. Always change the filter and consider a new conductor plate above 150k miles. Check level at operating temp.
Use a Torque Wrench
Whether reinstalling a drain bolt or diff fill plug, a click-style torque wrench prevents cracked pans or stripped threads.
Bleed Power Steering
After filling, turn steering lock-to-lock with engine off several times to purge air. Top off with Pentosin CHF-11S. Start engine and repeat.
Keep a Maintenance Log
Record every fluid change, product used, mileage, and date. Essential for resale value and tracking service intervals on high-mileage T1Ns.

Recommended Service Intervals
| Fluid | Interval (miles) | Time | Notes |
|---|---|---|---|
| Engine Oil + Filter | 5,000–7,500 mi | 6 months | Whichever comes first. Shorter interval for severe duty. |
| Coolant | 60,000 mi | 5 years | Full flush and refill. Use MB 325.0 spec coolant (Zerex G-48 or G-05). |
| Transmission Fluid + Filter | 40,000–60,000 mi | - | Pan drop service. Replace conductor plate if above 150k. |
| Differential Fluid | 60,000 mi | - | Sooner if towing frequently or operating in extreme conditions. |
| Brake Fluid | - | 2 years | Moisture absorption degrades performance regardless of mileage. |
| Power Steering Fluid | 60,000 mi | - | Inspect for contamination or dark color at each oil change. |
| Fuel Filter | 20,000–30,000 mi | - | Drain fuel-water separator at every oil change. |
Intervals based on Mercedes-Benz recommendations and common T1N community practices. Adjust for severe conditions (towing, dusty environments, extreme temperatures).
