The typical cost to replace a water pump on an INFINITI G35 is about $500 to $1,100 at an independent shop, with dealer quotes often higher. The final price depends on parts, labor rates, and whether any additional timing-system components need replacement.
The G35 uses a 3.5-liter V6 engine with a timing chain. The water pump is driven by the timing system and sits behind the timing cover, making this a labor-intensive repair that may involve removing multiple components, draining coolant, and possibly replacing the thermostat and seals. Prices vary by year, trim, and local labor rates, so quotes can differ significantly.
What affects the price
The following factors influence the final bill for water pump replacement on a G35:
- Labor rate and shop location: Urban areas or dealer service centers typically charge more than independent shops.
- Parts choices: OEM versus aftermarket water pump, plus the thermostat, gasket, coolant, and any hoses.
- Extent of work: If wear is found in timing-chain components (guides, tensioners), they may require replacement.
- Optional add-ons: Serpentine belt replacement, coolant service, and disposal fees.
- Vehicle condition and accessibility: Higher mileage or complex routing can increase required labor time.
- Warranty or service contracts: Some shops offer partial coverage for parts or labor.
Understanding these factors helps you compare quotes and plan your budget.
Estimated price range and breakdown
Here is a typical breakdown you might see in a quote, covering parts, labor, and potential extras.
- Parts: Water pump (OEM or aftermarket), thermostat, gasket, coolant, and any required seals or hoses. Estimated parts total: $120–$230.
- Labor: Time to complete the replacement, typically 4–6 hours at an average shop rate. Estimated labor: $300–$750 at independent shops; dealer rates can push this higher.
- Potential extras: Timing chain guides/tensioners or other timing components if worn, plus additional cooling system components. Estimated extras: $150–$350 if needed.
Concluding note: If the pump failure is tied to timing-system wear or if the water pump sits behind the timing cover, the job can be more labor-intensive, increasing the final cost. Always request a written, itemized estimate before authorizing work.
Summary
In short, replacing a water pump on an INFINITI G35 typically runs from about $500 to $1,100 at an independent shop, with higher costs at a dealership—often $900 to $1,500—especially if extra timing components or cooling-system parts are required. Getting multiple quotes and clarifying what’s included helps ensure you’re budgeting accurately and avoiding surprises.
