Cooling Systems Restrictions

In Simple Terms

F1 teams can only use fuel's natural cooling properties in their engine's cooling system. They cannot use other liquids (like special coolants) to create additional cooling through evaporation tricks. This keeps all teams on equal footing and prevents engineering loopholes.

• Teams cannot exploit evaporative cooling from any fluid except fuel
• Fuel's latent heat can only be used for its normal combustion purpose, not as a cooling mechanism
• This rule prevents teams from gaining unfair thermal management advantages through creative fluid engineering
• The restriction applies to all cooling systems including intake air cooling
