ARTICLE 7: OIL AND COOLANT SYSTEMS
7.1 Location of oil tanks:
All oil storage tanks must be situated between the front wheel axis and the rearmost gearbox casing longitudinally, and must be no further than the lateral extremities of the survival cell are from the longitudinal axis of the car.
7.2 Longitudinal location of oil system:
No other part of the car containing oil may be situated behind the complete rear wheels.
7.3 Catch tank:
In order to avoid the possibility of oil being deposited on the track, the engine sump breather must vent into the main engine air intake system.
7.4 Transversal location of oil system:
No part of the car containing oil may be more than 700mm from the longitudinal centre line of the car.
7.5 Coolant header tank:
The coolant header tank on the car must be fitted with an FIA approved pressure relief valve which is set to a maximum of 3.75 bar gauge pressure, details of the relief valve may be found in the Appendix to these regulations. If the car is not fitted with a header tank, an alternative position must be approved by the FIA.
7.6 Cooling systems:
The cooling systems of the engine must not intentionally make use of the latent heat of vaporisation of any fluid.
7.7 Oil and coolant lines:
7.7.1 No lines containing coolant or lubricating oil may pass through the cockpit.
7.7.2 All lines must be fitted in such a way that any leakage cannot result in the accumulation of fluid in the cockpit.
7.7.3 No hydraulic fluid lines may have removable connectors inside the cockpit.
