Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Handling Precautions For Silicone-Containing Spray
When a silicon-containing lubricant is used, rust inhibitor or glazing agent adheres to the electrical contact of the relay or switch, which may produce silica dioxide (SiO2 ). This may cause poor connection.
- Never spray directly to the electrical equipment.
- When using the spray close to the electrical equipment, always put the cover on it. Special care must be exercised especially when using the spray to the locations shown in the figure below and their surrounding areas.
- If the residual silicone remains in the vicinity of the electrical equipment after the spray has been used, the vaporized silicone stands around the electrical equipment and it may adhere to electrical contact. After using the spray, be sure to wipe the silicone off with a cloth.
- Even when using the spray to the place away from the electrical equipment, the droplet of the spray may be splashed to the periphery. Use as small amount of spray as possible, and take care not to splash the silicone to the periphery.NOTE:
The "silicon" used in this information refers to "silicone", that is, silicon polymer.Β
