After installing a new thermostat, Proton car owners have noticed that the temperature gauge fluctuates when driving. It warms up initially, but as soon as the car is in motion, the temperature drops. This issue has been reported in various Proton models.
Proton Brake Light Fuse Blowing
The brake light fuse is an essential safety feature in Proton cars. However, some owners have faced issues with the fuse blowing, which is potentially linked to the central locking system. In some cases, the fuse blows as soon as the brake pedal is pressed.
Central Locking Activation
Proton car owners suspect that the blowing of the fuse may be connected to the activation of the central locking system when the brake pedal is pressed. This issue has been reported in models like the 2010 Proton Gen 2 1.6.
Fuse Replacement
To resolve the issue of a blown brake light fuse, Proton car owners may need to replace the fuse. However, it is crucial to identify and address the cause of the fuse blowing, which may be related to the central locking system.
Proton Water Pump Replacement
The water pump in a Proton car is responsible for cooling the engine. When it malfunctions, it can cause overheating and other issues. Replacing the water pump can be a challenging task due to limited space around it.
Limited Space for Replacement
Proton car owners have reported that replacing the water pump in models like the 1997 Proton Persona sdi can be difficult due to the restricted space around the pump. It is important to consider the necessary adjustments when attempting to replace the water pump.
