3.7L (VQ37VHR) - Base Coupe
Petrol
While stationary, listen closely for a 'clunk' or 'knock' from the rear when shifting from Neutral to First, or First to Reverse. This can occasionally indicate wear in the differential bushings, which is something to be aware of in these performance coupes.
Check this by performing a low-speed maneuver with the steering wheel at full lock in both directions. If you notice a clicking noise, it might suggest the CV joints are starting to show their age.
While driving, monitor the clutch pedal feel. If it feels particularly heavy or exhibits inconsistent engagement, it is worth keeping in mind that the Concentric Slave Cylinder (CSC) is a component that often requires attention in Z34 models as they clock up the kilometers.
Accelerate briskly in a higher gear at lower RPMs to check for any 'shuddering' or hesitation. While the VQ37VHR is robust, it is always wise to ensure the fuel system and spark plugs are providing a smooth delivery of power.
Consider a full fluid flush, including the manual transmission and differential oil, to keep things shifting smoothly.
A sensible time to inspect the condition of the suspension bushings and verify the serpentine belt hasn't developed any micro-cracking.
Usually the stage where one might look at the cooling system health, specifically checking the radiator and hoses for any signs of brittleness.
Check the engine oil level regularly, as the high-revving nature of the VQ engine means it appreciates being kept topped up.
Keep an eye on the coolant reservoir to ensure the levels are consistent and there are no signs of leaks.
Inspect the tire tread depth periodically, especially on the inner edges, which can wear faster due to the Z's factory alignment settings.
Ensure the air filters are clean, as the dual-intake setup on the 370Z likes to breathe freely for optimal performance.
Monitor the brake fluid color; keeping it fresh helps maintain that crisp pedal feel these cars are known for.
Estimated repair costs if issues arise
If the clutch feel changes significantly or you experience shifting issues, you might eventually need to budget for a heavy-duty CSC upgrade. Replacing this involves removing the gearbox, so it is often a good time to consider a clutch upgrade simultaneously.
Depending on the car's driving history, the factory rubber bushings in the rear subframe can deteriorate over time. You might want to set aside funds for an aftermarket poly-bushing kit to restore that factory-fresh tightness.
In very high-mileage examples, it is worth keeping in mind the oil gallery gaskets behind the front timing cover. If oil pressure drops, this is a significant job that requires engine access, so it is something to keep in the 'future budget planning' file.
