What are the symptoms of a faulty calorstat?
Content
The calorific value of your car's engine plays a decisive role in regulating the coolant temperature. Indeed, this allows the engine to operate correctly and avoids the risk of overheating. In this article, we will tell you about the operation of the kalorstat, as well as the warning signs of a faulty kalorstat.
🌡️ What is the role of kalorstat?
It is located at the inlet of the hose at the height of the cooling radiator and has the shape Vanne which is an integral part of the cooling system. The cooling circuit contains a liquid consisting of glycol which transports the calories excreted jogging to the radiator, where the outside air enters to reach Heat exchange... Thus, it is possible to regulate the temperature of this coolant between 95 ° C and 110 ° C by performing the opening and closing phases. Kalorstat is required for support engine at the right temperature and prevent it from overheating.
On the other hand, kalorstat allows limit fuel consumption, avoid wear premature engine and reduce emissions of pollutants exhaust.
True referral tool, it works like thermostat and allows you to adjust the amount of coolant passing through the circuit and, in particular, inside the radiator.
🔎 How does Kalorstat work?
The calorostat will work differently depending on temperature your engine. Indeed, it will not behave the same if your car's engine is cold or hot:
- When the engine is cold : this situation occurs when you are at rest, the calorostat will work very weakly because the cooling circuit does not have to run at full speed. By blocking the coolant in the radiator, the engine can reach its optimum operating temperature faster. This allows you to shorten the heating time and, therefore, limit fuel consumption;
- When the engine is hot : in this particular case, the kalorstat valve alternates between the opening and closing phases. It allows coolant to pass through to cool the engine before it reaches excessively high temperatures.
The calorostat can know the temperature of the system due to its composition. Indeed, it consists of thermosetting wax... For example, when the system is hot, the wax expands and activates the opening valve, and when it is cold, the wax draws in and closes that valve.
🛑 What are the signs of a faulty calorstat?
There are several symptoms of faulty calorstat. Whatever it is, it means that kalorstat is locked in either open or closed position, these are the only two types of failures that you may encounter in this section. The symptoms of blocked calorstat are as follows:
- Excessive fuel consumption : the valve of the calorstat remains open at all times;
- Black smoke comes out of the exhaust pipe : open position is saved;
- Le seer engine malfunction may catch fire : present on the dashboard, orange;
- Engine overheating : the calorostat is closed and no longer supplies coolant to the system;
- Calorstat leak : the engine cools less well.
When the calorstat is blocked, you should respond as quickly as possible by contacting an experienced mechanic to carry out the necessary repairs. Indeed, without repairing the calorstat, your engine can be seriously damaged, ranging from a simple burn to the cylinder head gasket and ending with engine damage. final engine breakdown. In this situation, the prices for repairs will be much higher.
💰 How much does it cost to change the calorstat?
To change your calorstat, it is really better to go to a professional than to try to carry out this replacement yourself. Since this part is related to the engine, any processing error can be fatal for it. Depending on the calorstat model (including water box or not) prices will vary significantly from single to double. On average, count between 10 € and 200 € for the most expensive models. As for the labor force, 1 to 2 hours of work are necessary to change the calorstat. Ultimately, the total cost of this service ranges from 100 € and 300 €.
The calorostat is a key element of the cooling system and ensures that your engine remains in good condition over time. Do not skimp on repairing or replacing the latter, because damage to the rest of the mechanical parts can be irreversible.
