The 2007-2010 Nissan Altima Repair Manual by Chilton, covering U.S. and Canadian versions of Altima models, is now available from The Motor Bookstore.
This manual was created specifically for do-it-yourself Altima owners who would like to perform their own car maintenance and repairs.
Nissan Altima cars come available as 2-door coupes and 4-door sedans, and are powered by a transversely-mounted engine, either a 2.5L in-line four or a 3.5L V6, all with sequential multi-port electronic fuel injection.
Note: this manual DOES NOT include hybrid model info.

VALVE SPRINGS, RETAINERS AND SEALS | REPLACEMENT
CLUTCH AND DRIVELINE
(Refer to illustrations 5.5, 5.7a, 5.7b, 5.13 and 5.15)
NOTE: Broken valve springs and defective valve stem seals can be replaced without removing the cylinder heads. Two special tools and a compressed air source are normally required to perform this operation, so read through this Section carefully.
If you want to leave the head on, obtain a special on-vehicle valve spring compressor (see illustration 10.1 in Chapter 2A).
Verify the availability of the correct spring compressor before beginning the job. If you can't get the special tools, then you'll have to remove the heads and use a clamp type valve spring compressor.
- Remove the intake manifold collector (see Section 8) and the valve cover(s) (see Section 4).
- Remove the timing chain (see Section 6) and the camshafts and lifters from both cylinder heads (see Section 7).
- Remove the spark plugs.
- Turn the crankshaft until the piston in the affected cylinder is at Top Dead Center (see Section 3). If you're replacing all of the valve stem seals, begin with cylinder number one and work on the valves for one cylinder at a time.
Move from cylinder to cylinder following the firing order sequence, turning the crankshaft 120-degrees to bring the next cylinder to TDC (see this Chapter's Specifications).
- Thread a long adapter into the spark plug hole and connect an air hose from a compressed air source to it (see illustration). Most auto parts stores can supply the air hose adapter.
CLUTCH | DESCRIPTION
- All vehicles with a manual transaxle use a single dry plate, diaphragm spring type clutch. The clutch disc has a splined hub which allows it to slide along the splines of the transaxle input shaft. The clutch and pressure plate are held in contact by spring pressure exerted by the diaphragm in the pressure plate.
- The clutch release system is hydraulically operated. The release system consists of the clutch pedal, the clutch master cylinder, the clutch release cylinder and bearing and the hydraulic line between the master cylinder and release cylinder.
- When force is applied to the clutch pedal to release the clutch, the clutch master cylinder transmits this movement to the clutch release cylinder and bearing.
As the bearing moves, it pushes against the fingers of the diaphragm spring of the pressure plate assembly, which in turn releases the clutch plate.
- Terminology can be a problem regarding the clutch components because common names have in some cases changed from that used by the manufacturer.
For example, the clutch release cylinder is sometimes referred to as a concentric slave cylinder, the driven plate is also called the clutch plate or disc and the pressure plate assembly is also known as the clutch cover.
