Temperature

Good day my dear masters and friends, my car is a 1.4 comfort sedan, the temperature sensor and thermostat of my gasoline vehicle have been changed, the master said it is doing the degirdam, but the temperature goes up to 100, the double fans are working but it is not decreasing, it is winter, it is not exceeding 100, but it should be decreasing slightly, it is not decreasing to 95 correctly, why is the gas stuck, it is constantly ticking, it is constantly switching from gas to gasoline, it is doing the same again, what could be the reason, please inform me

First, you need to check the vehicle's temperature gauge (ECU) to determine if there's a problem with it. If the gauge is the issue, which is common in 206 vehicles. If the first fan isn't activating, you need to check the fan relays. If it's still not working, the entire fan system should be checked. If you've verified that all of these are working correctly and the temperature still doesn't drop even with the fan running, it indicates a blockage in the cooling system. If the radiator, water flanges, water pipes, water channels within the engine block, etc., are blocking the water flow, the temperature won't drop. If the water flow is blocked, the water flow won't drop. If the water flow or thermostat has been replaced, these could be the problem. If the automatic switching from LPG to gasoline is occurring, it could be due to a lack of circulation. If the LPG regulator doesn't receive enough hot water, the vehicle will switch directly to gasoline. Of course, this should be checked and thoroughly inspected.
