What temperature is needed to heat the headlight cover for removal?
2 Answers
To remove the headlight cover, it needs to be heated to around 120 degrees Celsius. Here is some additional information: 1. Headlight cover: Most car headlight covers are made of polycarbonate (PC) or polymethyl methacrylate (PMMA) plastic through injection molding. Over time, they can become yellowed and aged, and may develop cracks, which can affect the vehicle's lighting. 2. Precautions: If the car headlight cover is damaged, the best and most effective solution is to replace it. Failure to replace a damaged cover may lead to water ingress, which not only reduces the brightness of the headlights but can also cause short circuits and damage to the electrical circuits.
Remember last time helping my neighbor deal with foggy headlights on his old Focus, I used a heat gun set at 140°C to evenly heat the edges of the lens. When the plastic softened and I heard the sizzling sound of adhesive separation, it was ready to work. This temperature is a safe value for most Japanese cars, while German cars with harder sealant might require 150°C. Special reminder: keep the heat gun moving constantly to avoid localized overheating that can cause lens blistering. Heat-resistant gloves are mandatory – once forgot to wear them and got blisters on my fingers that hurt for three days.
