Top 5 Cold Weather Failures - and How to Prevent Them with Preheaters

When winter hits hard, engines, batteries, and fuel systems don’t just slow down—they fail. We know a thing or two about this in Montana where the average temperature in January is -5°F. Whether you’re managing a fleet, maintaining a backup power system, or operating equipment in remote or extreme climates, cold weather failures can cost thousands in downtime, repairs, and lost productivity.

Here are the top 5 most common cold weather failures—and how Universal Preheaters™ offer reliable, low-watt solutions to prevent them before they happen.

1. Diesel Fuel Gelling

The Problem: As temperatures drop, paraffin wax in diesel fuel starts to crystallize. At around 15°F (-9°C), the fuel can thicken into a gel, clogging filters and fuel lines, and preventing the engine from starting or running properly.

The Solution:
Install fuel filter and tank preheaters to maintain a consistent fuel temperature above the gel point. ETIP’s peel-and-stick preheaters prevent wax crystal formation, ensuring clean flow and quick startups—even in Montana conditions.

Product Match: Universal Fuel Filter Heater, Tank Heater Pads
Ideal For: Fleet trucks, construction equipment, standby generators

2. Dead or Weak Batteries

The Problem: Batteries lose up to 60% of their cranking power at 0°F. Cold temperatures increase internal resistance, slow down chemical reactions, and reduce battery efficiency, leading to failed starts and system outages.

The Solution:
Use battery heater pads to keep the battery’s core temperature in its optimal range. A warm battery means higher Cold Cranking Amps (CCA), longer lifespan, and more reliable starts.

Ideal For: Vehicles, remote equipment, telecom and emergency backup systems

3. Thickened Engine Oil

The Problem: Engine oil thickens in the cold, creating drag and making it harder for the engine to turn over. This increases wear during startup, strains starter motors, and can trigger cold-start failures.

The Solution:
Apply a preheater to the oil pan or engine block to keep oil warm and flowing. Unlike traditional block heaters, Universal Preheaters™ are low-watt, adhesive-mounted, and require no plumbing or modification.

Product Match: Engine Oil Pan Heater, Universal Block Heater
Ideal For: Diesel engines, backup power systems, small gas engines

4. Hydraulic System Slowdowns

The Problem: Hydraulic fluid can thicken dramatically in low temperatures, causing sluggish movement, pressure build-up, cavitation, or outright system failure in snowplows, lifts, or off-road equipment.

The Solution:
Install hydraulic reservoir or line preheaters to maintain optimal fluid viscosity. By gently warming the fluid, you’ll prevent pressure spikes and ensure responsive, smooth operation from the first start.

Product Match: Hydraulic Reservoir Heater, Inline Hose Heater
Ideal For: Utility trucks, plows, aerial lifts, loaders

5. Frozen or Condensated Components

The Problem: Moisture can freeze in fuel/water separators, air intakes, breathers, and sensors. Even small ice crystals can cause malfunctions or cracks in critical components.

The Solution:
Use targeted preheaters to apply gentle, consistent warmth to vulnerable areas. Our flexible, low-profile pads are easy to install and maintain.

Product Match: Custom-Sized Universal Heater Pads
Ideal For: Sensors, separators, air valves, pump housings
