Thermostats can get sticky, causing the engine temperature to stray from the optimal range.
If so, it would be repaired prior to replacing the thermostat. Since it is usually not known how badly the engine overheated, the mechanic will also try to determine if there is evidence that the cylinder head gasket was blown. However, since there are other causes of overheating, a mechanic will thoroughly inspect the cooling system prior to condemning the thermostat. A thermostat with the valve stuck closed is a common cause of engine overheating. If so, the car’s safe to be back on the road.When to consider replacing the engine cooling system thermostat: Check if the temperature gauge is reading fine.Tighten the radiator cap and add the coolant back or replace it if it’s old.Replace the hose if it’s leaking or worn out. Clean and reassemble the radiator hose, hose clamp, and thermostat housing.
#Cost to replace coolant thermostat install
Remove the old thermostat and install the new thermostat.Test the new thermostat by placing it in a bucket of boiling water.Ensure the new thermostat and gasket are similar to that of the old thermostat. Remove the radiator hose with the hose clamp and take apart the thermostat housing and gasket.Find the thermostat by locating the radiator hose.Drain enough to bring the coolant level below the thermostat housing. Drain the engine coolant (antifreeze) through the radiator cap.Ensure the vehicle has cooled down to prevent burns.Here’s a general guideline on how a mechanic would perform a thermostat replacement:
#Cost to replace coolant thermostat professional
So, it’s best to leave the replacement to a professional mechanic rather than attempt a DIY repair. Thermostat replacement requires a fair bit of knowledge and experience to ensure that the components and the cooling system work efficiently. This can include a radiator hose replacement, water heater installation, or air conditioner repair (AC repair). Īs a safety measure, you could replace your existing thermostat when your vehicle’s cooling system components are serviced. So, most mechanics recommend a thermostat replacement after 10 years. Here are the different types available for your car:Ī car thermostat does eventually wear down and fail. Vehicle thermostats may be either mechanical or digital. What Are The Different Types of Thermostats? This keeps the engine at an optimal temperature (between 195☏ to 225☏), preventing overheating. When the engine hits a certain temperature (usually around 195☏), the valve opens, allowing the radiator to cool the liquid coolant. This, in turn, promotes efficient fuel use and reduces engine deposits. It traps the engine heat, helping it quickly heat up to the right temperature. When you start your car, the thermostat valve is closed, preventing the coolant flow from reaching the radiator and cooling the engine. It’s an important part of your vehicle’s cooling or heating system or HVAC system, helping regulate the temperature setting of the vehicle. The thermostat helps keep your engine running at the right temperature. Here are quick answers to four questions about thermostats and their replacement: 1.
