EngineCoolantLevelCheck
Fordetails of the specification of fluid used by this system and the system capacity, please refer to:
Engine Coolant Specification.
McLaren Customer Racing advisescustomersto use a 75:25mixtureof de-ionized water and
antifreeze.
To check the engine coolant level:
1. Make sure the engine iscooland switched off
2. Slowly unscrew the header tank pressure cap half a turn and allow excess pressure to escape
3. Unscrew andremove theheader tankpressurecap
4. The engine coolant level is correctwhen the level isbetween thelowerandupper steps inside
thefillerneck
5. Using thecorrectspecification of fluid anddilutionratio, topupthecoolantif necessary

please refer to: Engine Coolant Specification.
6. Refit the header tank pressure cap and turn clockwise until thestop
Figure 2:EngineCoolantFillerCap and LevelCheck
NOTE: Please exercise caution when removing the header tank pressure cap whilst the engine is
still warm.
NOTE: Engine coolant is toxic, please exercise caution.
NOTE: McLaren Customer Racing recommends that the coolant level is set prior to the engine
reaching operational temperature.
NOTE: Do not add any type of water wetter to the recommended coolant. The addition of a
water wetter may cause a build-up, which could block the heat exchangers causing temperature
increase.

1. Start the engine making sure thevehicleis stationary and on a level surface
2. Engage neutral andapply thefootbrakeusingthe leftfoot

8. Iftheengine oil is below thetarget
level, top up the oil in accordance with the following procedure:
Figure6:Engine OilFillerCap
a. Turn the engine and vehicle ignition OFF
b. Remove the engineoil fillercap
c. Using the correct specification of oil, topup with engine oil to the correct level using 0.25
litresteps
NOTE: The maximum oil volume for the engine is 6.4 litres. This total volume must not be
exceeded regardless of the oil status level reading on the left-hand display.
d. Refit the engine oilfillercap and turn clockwiseuntilthestop
e. Turn the vehicle ignitionON
f. Navigate to the oil statuspage,in the vehicle info section of theleft-handdisplay
9. Repeat steps 7 and 8 until the oil level iscorrect
NOTE: Over-filling the engine oil will cause oil seepage in the vacuum system, affecting engine
performance. This will also lead to excessive smoke through the exhausts until the excess oil is
burned.

NOTE: Avoid contact of brake fluid with painted surfaces. Wash off any brake fluid with water
immediately.
NOTE: If the brake system is dismantled a brake bleed will be required. Following removal of any
brake lines or ABS modulator from the car, McLaren Customer Racing recommends a full ABS
bleed routine is competed using the MDS tool. Please refer to:
ABS Modulator Bleed.
NOTE: Make sure all brake fluid lines are fitted to the correct locations on the Hydraulic
Power Unit. Please refer to: Hydraulic Power Unit.

FuelConsumption
Fuel consumption should typically average 0.55 0.75 L/KM for normalrunning (depending on driver
and track characteristics).
There may be somevariation in thisvaluedue to the torque demand nature of the engine calibration,
which will adjust certain parameters to meet the target, including, but not limited to, fuel used,
throttle body opening, and ignition timing.
Therunning temperatures andambient conditions experienced by the vehicle will also have some
bearing on thefuelconsumption,astheseparameters arealso considered to meet the torque
demand target.
