Daimlerchrysler Nitro Technical Manual – Factory Specs for the 2007 Model

If you’ve ever had to pull apart a front suspension on a Nitro and found the sway bar link torque from a third-party source was off by 10 ft-lb, you know the headache. Wasted time, stripped threads, a part that rattles loose. That’s why you need the factory file. This Daimlerchrysler Nitro Technical Manual runs 577 pages of nothing but OEM breakdowns, torque sequences, and part callouts. No guesswork, no “close enough” aftermarket nonsense. You get the exact same documentation Daimlerchrysler handed to dealer techs in 2007.

I’m Mike Callahan. I’ve been turning wrenches in San Antonio for 28 years, and I’ve seen what happens when someone trusts a reprinted manual that says “torque to spec” without listing the spec. This manual lists them. Every Group—from the Mopar accessories to the rear axle vent—is laid out with figure numbers and hardware references. You don’t have to wonder if the 2.8L diesel uses the same water pump as the 3.7L gas engine. Look at Group 7: separate radiator figures for each engine, separate drive pulley diagrams. That matters when you’re ordering parts.

VIN Plate Decoding: First Step Before Any Repair

Page 1 of this Technical Manual shows you how to decode the 17-position VIN for a 2007 Nitro. Country, make, GVWR range, vehicle line, body style, engine code. Need to know if the Nitro in your bay is a 4×2 or 4×4? Position 5: T for 4×2 left-hand drive, U for 4×4 left-hand drive, 9 for right-hand drive. Engine codes at position 8: 5 for the 2.8L I4 turbo diesel, K for the 3.7L V6 gas, 1 for the 2.4L I4 gas DOHC. This saves you from ordering the wrong water pump or brake lines. Cross-check that against DaimlerChrysler Nitro 2008 VIN Plate Decoding Information if you’re working on a later model, but this manual covers 2007 exclusively.

Group 5 Service Brakes – Factory Disc and Hydraulic Specs

Brake jobs are where people get sloppy. The manual devotes multiple figures to front and rear disc brakes (Fig. 5-110 and 5-210), plus the power brake booster (5-310) and master cylinder (5-410). You’ll see the correct orientation for the brake lines from the HCU to the master cylinder (Fig. 5-510) and the exact hardware for the front and rear lines (5-520, 5-530). Bleeding sequence? That’s in there. Use the factory pedal assembly (Fig. 5-610) and you won’t end up with a soft pedal. One warning from experience: don’t reuse the old banjo bolts on the master cylinder. Manual shows part numbers; match them.

Why This 577-Page Daimlerchrysler Nitro Technical Manual Beats Aftermarket Copies

Aftermarket PDFs cobble together scans, drop torque specs, or use generic wiring colors. This manual is a direct OEM release for the Nitro—no reprints, no third-party guesses. Every figure number (e.g., Fig. 7-105 for the 3.7L/4.0L radiator) corresponds to the official Mopar parts catalog. If you need to order a charge air cooler for the diesel (Fig. 7-175), the part reference is right there. The 577 pages are paginated with the original Daimlerchrysler layout, so you can hand the file to a junior tech and say “look up Group 2, Fig. 2-110 for strut installation.” They’ll find the same diagrams I used in 2007.

Front Suspension and Drive – Strut, Sway Bar, and Axle Assembly

Group 2 covers the front suspension and drive. Fig. 2-110 shows the strut and spring assembly. Fig. 2-120 is the front sway bar. Torque on the sway bar link nuts? Factory spec is given. I’ve seen aftermarket charts call for 55 ft-lb when the real number is 41 ft-lb. That’s the difference between a bar that works and a snapped link. The manual also covers the front axle housing (2-310), drive shafts (2-210), differential (2-610), and skid plate (2-810). If you’re dropping the cradle (Fig. 2-130), you need the bolt tightening sequence. Page? It’s in there.

Does the Manual Cover the Parking Brake and Clutch?

Yes. Group 4 covers the parking brake lever and cables (Fig. 4-110) and the rear disc parking brake assembly (Fig. 4-120). Group 6 covers the clutch assembly (Fig. 6-110), housing for both the EK0 and EN0 transmissions, hydraulic controls (6-310), and clutch pedal (6-410). If you’re swapping a clutch on a 4×2 Nitro, you’ll need the housing differences. The manual spells them out.

Cooling System – 2.8L Diesel vs 3.7L/4.0L Gas Engines

Group 7 is where the manual earns its keep. Separate radiator part figures for the diesel (Fig. 7-110) and gas engines (Fig. 7-105). Separate water pump diagrams for 3.7L (7-220), 4.0L (7-225), and diesel (7-235). Drive belts and pulleys are also split by engine. The diesel uses a charge air cooler (Fig. 7-175) and a coolant degasser tank (Fig. 7-320) instead of the gas engine tank (7-310). Don’t mix them up. The 577 pages include every pulley and belt routing. If you need to replace the drive belt on a 3.7L, Fig. 7-520 shows the belt path.

Is this manual specific to the 2007 Daimlerchrysler Nitro?

Yes, it covers model year 2007 only.

What engine options does the manual include?

The VIN decoding on page 1 lists engines: 2.8L I4 turbo diesel (code 5), 3.7L V6 gas (code K), 2.4L I4 gas DOHC (code 1), and 2.5L turbo diesel (code 7). The manual’s cooling, drivetrain, and accessory sections provide separate figures for each engine. For example, Group 7 has separate water pump and radiator diagrams for the 2.8L diesel versus the 3.7L gas. If you’re rebuilding a 2.4L engine, you’ll find its specific front suspension cradle and accessory drive belt routing. The manual covers all variants (4×2, 4×4 left-hand drive, and right-hand drive) with the correct part callouts. This level of detail means you don’t have to guess which water pump or belt fits your particular Nitro—the VIN code tells you, and the manual gives you the exact figure number to reference.
