Maintenance is both simple and complicated. The water pump is driven by the timing chain, but it can be removed without removing the chain, and there are coolant drains on either side of the block.
Valve clearance is adjusted by installing lifters of different thickness, which means the camshafts must be removed.
The fuel pressure regulator and fuel filter are both inside the tank, but they can be accessed under the rear seat.The wheel speed sensors on vehicles with an automatic transmission are different from those with a manual, but resistance is the same.
Service bulletins were issued for harsh shifting in the automatic transmission (repair/replace shift solenoid assembly), no-crank after cold-soak below 0°F, and hesitation caused by a faulty MAF.
A recall was issued for faulty crank position sensors: This engine has two, and they're different from each other.The Maxima has always been a driver's car, and even with a twist beam rear axle, this four-door sedan will almost run with the Z.
When test-driving, enjoy the ride.
