Will Heet Unfreeze a Fuel Line?
Yes, Heet (specifically the yellow bottle, which contains methanol) is designed to help unfreeze fuel lines and prevent them from freezing again. Here’s a closer look at how it works and when to use it.
What Is Heet?
Heet is a fuel additive that absorbs water in the fuel system. There are two types:
- Yellow bottle: Contains methanol, used for removing water and unfreezing fuel lines.
- Red bottle (Iso-Heet): Contains isopropanol, better for fuel injector cleaning and water removal in colder climates.
How Does Heet Work to Unfreeze Fuel Lines?
When water in the fuel lines freezes, it can block fuel flow and prevent your car from starting or running properly. Heet:
- Mixes with the water in the fuel line.
- Lowers the freezing point of water, making it easier to melt.
- Helps to dissolve the ice, allowing fuel to flow freely.
When to Use Heet
- If your car won’t start on a cold morning, and you suspect a frozen fuel line.
- As a preventive measure in below-freezing temperatures.
- After driving through wet or snowy conditions with low fuel levels.
How to Use Heet Safely
- Buy the yellow bottle of Heet.
- Pour it into your gas tank—a full bottle treats up to 20 gallons.
- Let it sit for a bit (or start the engine if possible).
- If the line is already frozen, give it 10–20 minutes to work.
Tips for Preventing Frozen Fuel Lines
- Keep your gas tank at least half full in winter.
- Use Heet regularly in freezing weather.
- Store your car in a garage or warmer area, if possible.
Conclusion
Yes, Heet can unfreeze a fuel line—especially the yellow bottle, which is designed for exactly this issue. It’s also a solid preventive tool during winter months, helping ensure your car stays running smoothly in sub-zero temps.
FAQs
Q: Can Heet damage my car?
A: No, when used as directed, Heet is safe for all gasoline engines, including fuel-injected and carbureted systems.
Q: Can I use Heet in diesel engines?
A: No. Heet is for gasoline engines. Use a diesel-specific water remover for diesel vehicles.
Q: How often should I use Heet?
A: In freezing weather, use with each fill-up or every couple of weeks as preventive maintenance.
