How does DEI Heater Hotter work?

Heater Hotter is specially formulated to accelerate the transfer of heat from your engine to the antifreeze. This allows your vehicle's heater to produce warm air much faster, even in very cold temperatures.

How quickly will I notice the effects?

The additive needs to cycle through your cooling system and mix with the existing antifreeze before it becomes effective. Once mixed, you can expect your heater to blow warm air up to 50% faster.

Is this safe for my cooling system?

Yes, Heater Hotter is safe to mix with all types of antifreeze and is compatible with aluminum radiators. However, your vehicle's cooling system and thermostat must be functioning properly for the additive to work as intended.
