What does the CODE35 Buick fault code mean?

[DeStella]

CODE35 Buick fault code indicates that the vehicle's engine temperature is too high. Below is a detailed introduction to the causes and solutions for engine overheating: 1. Dirt blockage on the outer surface or inside of the radiator: Dirt blockage on the outer surface or inside of the radiator affects heat dissipation or coolant circulation. The solution is to clean the radiator or replace it with a new one. 2. Insufficient or leaking coolant: If the coolant is insufficient or leaking, the solution is to replenish the coolant, and for leaks, the cause needs to be identified. 3. Other situations: For instance, if the high temperature is due to poor grounding between the engine and the vehicle frame, causing inaccurate feedback values from the coolant temperature sensor. The solution is to have a professional electrician check it or handle it yourself.
