Product Information
Full details
The Design Engineering Heater Hotter Radiator Additive is for vehicle owners looking to speed up their engine's warm-up time, leading to a faster-acting heater, especially during cold weather. While it significantly improves cabin comfort in winter, users should note that its primary function is related to heater performance, not engine cooling in extreme heat. This additive works by reducing the surface tension of the coolant, enhancing heat transfer for quicker engine warm-up and thus faster cabin heat.

Extended Product Information
FAQs
How does this additive make my heater work faster?
It reduces the surface tension of your coolant. This allows the coolant to transfer heat from the engine to your heater core more efficiently, resulting in warmer air being produced by the heater sooner.
Is this safe for my engine and cooling system?
Yes, DEI Heater Hotter is formulated to be safe for all engine components and is compatible with all types of coolants and antifreeze.
When should I add this product?
It's best to add the product during a routine coolant flush and fill, or when topping off your coolant. Ensure the engine is cool before application.
How much of the product do I need to use?
Typically, one 16oz bottle treats systems with a 4-6 gallon coolant capacity. Always check your vehicle's owner's manual for your specific coolant volume.
Will this product help my engine run cooler in the summer?
DEI Heater Hotter is designed to improve warm-up speed, not to lower operating temperatures. Its primary benefit is faster heater performance in cold weather.
Can I mix this with existing coolant?
Yes, it is designed to be added to existing coolant and antifreeze without affecting their protective properties.
How long does the effect of the additive last?
The additive remains effective in the coolant system until the coolant is next flushed.
Troubleshooting
Heater still not warming up quickly
Ensure the correct amount of additive was used and that the coolant system is properly filled. Check for other potential issues like a clogged heater core or a faulty thermostat.
Coolant level appears low after adding
The system may have drawn the additive into the engine block. Top off the coolant reservoir to the appropriate level and monitor for leaks.
Additive appears to have separated or is cloudy
This is generally normal and does not affect performance. The additive is designed to work within the coolant mixture.
Pros and Cons
Pros
- Provides faster cabin heat in cold conditions.
- Helps clear windshields quicker by defrosting sooner.
- Compatible with all standard coolant and antifreeze types.
- Simple pour-in application requires no special tools.
- Reduces coolant surface tension for improved heat efficiency.
Cons
- Does not directly improve engine cooling capacity in high temperatures.
- Effectiveness is most noticeable in cold weather operation.
- Requires access to the vehicle's coolant system for application.
- May not be suitable for all specialized cooling systems without checking compatibility.
- The benefit is primarily for heater warm-up, not engine performance tuning.
Setup, Compatibility & Care
Setup:
- Ensure your engine is cool before opening the radiator cap or coolant reservoir.
- Consult your vehicle's owner's manual for the correct coolant capacity and fill location.
- Add the recommended amount of DEI Heater Hotter (typically one 16oz bottle per 4-6 gallons of coolant capacity) directly into the coolant reservoir or radiator.
- Replace the radiator cap securely.
- Start the engine and let it run for a few minutes to circulate the additive.
Compatibility:
- This additive is compatible with all types of conventional and extended-life coolants and antifreeze (e.g., green, orange, pink, yellow). It does not alter the protective properties of your existing coolant.
Care:
- No ongoing maintenance is required after application. The additive is designed to remain in the system until the next coolant flush.
