Can I replace car thermostat myself?
Yes, you can typically replace a car thermostat yourself, as long as you have some basic mechanical skills and the right tools. Replacing a car thermostat is a relatively straightforward task that many DIY mechanics can handle with a little guidance.
What is a Car Thermostat?
A car thermostat is a critical component in the vehicle's cooling system. It is responsible for regulating the flow of coolant through the engine, helping to maintain the optimal operating temperature. When the engine is cold, the thermostat blocks the coolant from circulating, allowing the engine to reach its ideal operating temperature quickly. Once the engine warms up, the thermostat opens to allow the coolant to flow through the radiator, dissipating excess heat.
Why Replace a Car Thermostat?
- Overheating Engine: A faulty or stuck-open thermostat can cause the engine to run too cool, leading to poor fuel efficiency and potential engine damage.
- Slow Warm-Up: A stuck-closed thermostat can prevent the engine from reaching its optimal operating temperature, resulting in a longer warm-up period and reduced performance.
- Coolant Leaks: A damaged or worn thermostat can cause coolant leaks, which can lead to further cooling system issues.
Replacing a car thermostat is a relatively inexpensive and straightforward repair that can help maintain the health and performance of your vehicle's cooling system.
How to Replace a Car Thermostat
Replacing a car thermostat typically involves the following steps:
- Locate the thermostat housing, usually near the top of the engine.
- Drain the coolant from the system, either by removing the radiator cap and allowing the coolant to drain or by opening the drain plug at the bottom of the radiator.
- Disconnect any hoses or wiring connected to the thermostat housing.
- Remove the thermostat housing and the old thermostat.
- Clean the housing and surrounding area to remove any debris or corrosion.
- Install the new thermostat, making sure it is oriented correctly.
- Reassemble the housing and reconnect any hoses or wiring.
- Refill the cooling system with the appropriate coolant and bleed any air pockets.
- Start the engine and check for any leaks.
It's important to follow the specific instructions for your vehicle, as the process may vary slightly depending on the make and model. Additionally, be sure to use the correct replacement thermostat, as they come in different sizes and temperature ratings.
How long does it take to replace the thermostat on a car?
An average thermostat replacement takes around 1 hour, with some taking as little as 30 minutes. More problematic replacements can take a little longer where there are issues accessing an awkwardly positioned part or if it's become seriously stuck in place.

Can I drive a car with a bad thermostat?
If you drive with a bad thermostat, your car could overheat, causing severe and expensive engine damage. And while it's technically possible to drive without a thermostat, we don't recommend it. Your car will not reach an acceptable operating temperature, resulting in higher fuel consumption and excessive engine wear.
Do I need to drain coolant before replacing my thermostat?
Loosen the top hose clip, then ease off the hose. Partially drain the cooling system first. With a normal top-mounted thermostat you need drain only part of the cooling system .
