The belt in my car is old and worn out. It has visible signs of aging, such as cracks, fraying, and discoloration. This deterioration could lead to reduced performance or even belt failure, which may affect the operation of essential engine components like the alternator, power steering, and air conditioning. To prevent further damage and ensure the reliability of my vehicle, I need to replace the belt as soon as possible.

No funcionan los ventiladores se reviso termostato y switch fan q fueron cambiados aún si no arrancan automáticamente, en obd se escaneó y no reconoce el sensor dice no data que puede pasar

I just bought a used 2004 Honda civic ex coupe and it started overheating. The previous owner said that he replaced the radiator, timing belt, water pump, etc. And gave me the old timing belt as proof. I replaced the thermostat to see if that was the issues but it was not. When I open the radiator cap to add coolant it is never full. Any ideas?

When you lower the front windows to clear the water on them they just come back up with the water on them. On my old golf the windows came up clean.
