Oil Pan Heater
Also called: silicone pad heater, glue-on pan heater, stick-on heater
A flat heating pad bonded to the bottom of the oil pan. It warms the oil itself — the thing that actually resists a cold crank.

Measure before buying
The whole pad must sit flat
Measure an uninterrupted area of bare pan—clear of ribs, curves, drain plugs and seams. Then choose the wattage recommended for the oil capacity. A larger pad hanging over an edge transfers heat poorly and will not last.

1. Clean
Remove oil, rust and coating exactly as instructed.
2. Bond
Apply once, fully flat, without trapped air.
3. Cure
Leave it unplugged for the complete adhesive cure time.

How it works
Cold-start wear comes largely from thick oil: at -30°C, conventional oil pours like honey and takes long seconds to reach bearings after start. A pan heater warms the oil directly, restoring flow and cutting that dry interval.
Silicone pad heaters bond permanently to a cleaned, degreased pan surface with high-temperature adhesive. Once cured, they're effectively part of the pan and shrug off slush and gravel.
Limits to know
A pan heater warms oil, not coolant — so the block, heads, and cab heater warm up slower than with a coolant-side heater. Many cold-climate drivers run both: a frost plug heater for the block plus a pan pad for the oil, on a single splitter cord.
Pros
- Cheapest effective permanent heater
- Easy DIY install
- Directly targets cold-oil wear
Cons
- Doesn't warm coolant or cab heat
- Adhesive install is one-shot — prep matters

Check the fitment for your own vehicle
Most passenger vehicles take a frost-plug element rather than this style. The fitment pages say which one your engine actually accepts.
