Car Thermostat Problems Solved

A faulty engine thermostat or car radiator thermostat can severely impact your vehicle’s temperature regulation.

If your car’s temperature gauge moves erratically, reads too high, or remains at ‘normal’ even while the engine is overheating, the cooling system thermostat may be failing. Get your cooling system thermostat checked by a specialist to identify the root cause.

When a thermostat fails, it typically gets stuck in an open or closed position. The symptoms can resemble those of a failing water pump or broken radiator. Natrad technicians can diagnose the exact issue and provide a suitable car thermostat replacement.

We also offer thermostat installation services to restore your engine’s cooling efficiency.

Car thermostats for all makes and models

Driving with a failed thermostat can damage your engine. Natrad offers conventional and bypass thermostats for all makes and models. Not sure what you need? Check your manual or ask your nearest Natrad technician for the right thermostat or gasket.

The thermostat regulates coolant flow to help your engine warm up efficiently, reducing wear, fuel use, and emissions. Whether faulty or an upgrade, we’ll help you find the right fit.

When it comes to improving your cooling system, we recommend a high-flow thermostat for high-performance driving, towing, or any scenario where the engine is under greater load. It allows up to 50% more coolant flow, reducing the need for a lower temperature thermostat. Ask a Natrad technician about professional car thermostat installation to improve performance and efficiency.

All Natrad radiators are backed by a nation-wide 3-year warranty supported by Adrad, Australia's leading radiator manufacturer and supplier.

FAQs

  • What can cause a thermostat to fail?

    There are four main reasons your car’s thermostat might fail:

    1. Overheating: Thermostats are sensitive to extreme heat. When operating temperatures get too high, the internal components can break down.
    2. Contaminated coolant: Sludge in the coolant can clog the thermostat, limiting flow and affecting temperature readings.
    3. Manufacturing defects: Like other car parts, thermostats can have defects that lead to early failure.
    4. Time: Years of heating and cooling eventually wear down a thermostat, making it less effective.

    To avoid costly issues, have your cooling system thermostat inspected regularly by a professional.

  • What happens when a thermostat goes out in your car?

    If your car radiator thermostat fails, your engine may overheat or display erratic temperature readings. You’ll want to contact a technician immediately to prevent serious engine damage.

  • How much does it cost to replace a thermostat?

    Most car thermostat replacements cost between $150 and $250, though this depends on the vehicle’s make and model. Premium or complex cooling system thermostats may cost more.

  • Can I continue to drive if my car thermostat isn't working?

    Driving with a faulty engine thermostat or thermostat cooling system puts your engine at risk. Overheating can lead to serious mechanical damage and expensive repairs.

  • How often does a car thermostat need to be replaced?

    Thermostats don’t have a strict replacement interval, but it’s smart to replace them if:

    • It’s more than five years old
    • Overheating has occurred
    • You’re replacing coolant

    We recommend having your car thermostat repair or replacement reviewed during scheduled servicing.

  • Can I change my car thermostat myself?

    DIY car thermostat installation is possible with proper tools and instructions. It’s also a good time to flush the coolant system to protect your new part from contamination.

    However, a faulty or failed thermostat isn’t always the root cause of cooling issues. You may have:

    For peace of mind, have a full cooling system inspection done by a Natrad technician.

  • Why is it important to choose a high-quality thermostat?

    A high-quality car radiator thermostat helps your vehicle maintain optimal temperature for:

    • Efficient fuel economy
    • Reduced engine wear
    • Lower emissions
    • Effective cabin heating
    • Preventing overheating

    Quality matters—especially when it comes to your engine thermostat and thermostat repair.
