Installation Tips

IMPORTANT SAFETY WARNING: Do NOT apply silicone, debris, dirt, or any material between the heater pad and the mounting surface. Any gap between the heater and the oil pan or reservoir can cause improper heat transfer, overheating, and may result in fire, damage to the vehicle, or personal injury. The heater pad must be applied directly to clean, bare metal.

Surface Preparation: Thoroughly clean and sand the reservoir or oil pan to clean, bare metal. Remove all oil, paint, rust, and debris.

Application: Peel off the backing and apply the heater pad directly to the reservoir or oil pan. Apply firm, even pressure.

Sealing: Use high-temperature silicone (such as Permatex 77BR or equivalent) to seal only the outer edges of the pad. Do not allow silicone to migrate underneath the heater.

Wiring: Route the power cord to a safe, secure location away from moving parts, sharp edges, or extreme heat sources.

Cold Weather Tip: Warm the mounting surface before installation (run the engine or use a heat gun). Keep the heater pad warm during application for maximum adhesion. A helpful tip is to plug the heater in for approximately 5 seconds prior to application.
