Chrysler Nitro R/T 2007 Service Manual – Factory OEM, 1799 Pages

I’ve been turning wrenches for 28 years, and the thing that kills a job faster than a stripped bolt is trusting third-party specs. You pull up some online PDF, it says “torque to 22 ft-lbs,” but it’s wrong. Then you’re buying new head gaskets and explaining to the shop foreman why the engine is leaking. That’s the kind of frustration that makes you want to throw a ratchet across the bay. For the Chrysler Nitro R/T 2007 Service Manual, there is no substitute for the OEM file. Chrysler designed, built, and tested the 4.0L V6, the Getrag 238 transmission, the NV245 transfer case – and this 1,799-page document is the exact same book their own dealership techs used. You’re not getting some reprint that cropped the margins; you’re getting a full-resolution scan of the factory manual, page for page, torque for torque.

Engine 4.0L Service Information – What the Book Covers

Turn to the first section and you’ll find the 4.0L engine disassembly procedure. On page 1, there’s a detailed figure (Fig. 82) showing the camshaft thrust plate, bolt, and O-ring with the Chrysler LLC part callouts. It doesn’t just say “remove the thrust plate” – it tells you the sequence, the bolt thread size (M8, by the way), and the tightening angle. Further into the chapter, the manual walks you through counterholding the cam gear and removing the right cam gear retaining bolt (Fig. 83, page 2). That kind of clarity saves you from snapping a bolt in the head or mis-timing the camshaft. You also get the full valve timing spec, knock sensor location, and spark plug tube depth measurements. I don’t trust aftermarket diagrams that guess at the thrust plate O-ring position – this book has the actual engineering drawing.

1799 Pages: Not a Quick Reference, a Full Manual

All 1,799 pages are scanned at high resolution. That means every schematic, every wiring connector view, every torque spec table is readable without squinting. The manual covers the R/T trim specifically – that’s the 4.0L V6 with the 545RFE automatic transmission. You won’t find generic “Nitro” procedures that mix up the 3.7L and 4.0L; this is the R/T-only book. Sections include engine mechanical, driveline, axles, brakes, steering, suspension, HVAC, body, and electrical. I’ve seen too many DIY guys buy the wrong manual for their trim and end up with a driveshaft removal procedure that doesn’t match their CV joint layout. This one avoids that.

Does It Cover the 4.0L V6 Only?

Yes. The manual is specifically for the 2007 Nitro R/T equipped with the 4.0L SOHC V6. It does not cover the 3.7L or the diesel variants. If you own an R/T, this is your book. The torque specs for the cylinder head bolts, the camshaft sprocket bolt, and the oil pan bolts are listed with the factory angles and thread-locker requirements. You also get the official Chrysler diagnostic procedures for the OBD-II system, including the crankshaft position sensor and the knock sensor. For the wiring diagrams, they are color-coded and show the exact connector pinouts – no guessing which wire is the signal ground.

Trust OEM Documentation – Skip Aftermarket Manuals

Aftermarket manuals often paraphrase the factory steps or omit critical warnings. This Chrysler Nitro R/T 2007 Service Manual is a direct copy of the OEM documentation released by Chrysler LLC. The pages have the original copyright notices and part numbers. When the manual says “apply Mopar Threadlocker to bolt threads,” that’s the exact spec. I’ve had to re-do jobs on customer cars where a Haynes manual said “use standard sealant” and it failed. Factory manuals also include the technical service bulletins (TSBs) that are integrated into the procedures – a resource you will not find in a third-party book. If you’re working on a manual transmission, the factory spec for the Getrag 238 gearbox is here; not in the aftermarket book that tries to cover every Chrysler since 1990. Check out the Chrysler Stealth 1993 Service Manual – 1286 Pages Factory OEM for a different platform, but for the 2007 Nitro R/T, this is the only one you want.

Camshaft Removal Procedure – What Page 1 Shows

On page 1, the manual shows the camshaft thrust plate bolt sequence with an O-ring. It tells you to push the camshaft out of the rear of the head approximately 3.5 inches before removing the gear. That’s the kind of detail you need to avoid breaking the cam journal. Page 2 continues with the rocker assembly counterhold method. For the 4.0L, the timing chain cover removal and cylinder head bolt torque are also in the same chapter. If you’re rebuilding the top end, you cannot skip this step.

FAQ: Two Common Questions

Is this the same manual the dealer uses?

Yes. It’s the identical OEM document Chrysler dealership technicians receive.

My Nitro R/T has the 545RFE automatic transmission. Does this manual include the transmission overhaul section?

The manual includes the complete transmission mechanical and hydraulic service procedures for the 545RFE, including torque converter specs, valve body blow-ups, and line pressure test ports. The section starts after the engine chapter and runs about 200 pages. You’ll find the shift solenoid resistance values, the band adjustment procedure (which requires a special tool, p/n [DATA NEEDED]), and the oil pump clearances. It also covers the external cooler line routing and the TCM diagnostic trouble codes. Anyone swapping a transmission or rebuilding one will need this section – the aftermarket manuals often omit the specific clutch pack clearances for the 4.0L R/T calibration. For related manuals, see Chrysler Stealth 1993 Service Manual – 434-Page OEM Factory Specs for a different engine, or Chrysler Colt/Summit Series 2000 Service Manual 1989 for an older chassis. External resources like Manual Transmission theory on Wikipedia or Manual Transmission rebuild videos from reputable sources can supplement, but trust the OEM print.
