Cooling system maintenance
General information:
The cooling system can be filled, bleed and emptied from a quick
release coupling fitted in the bleed line leading from the front mounted
side coolers, rearwards to the expansion tank in the engine bay.
The valve in the expansion tank allows the exhaust of steam at a
pressure of 1.4 bar (+/- 0.1 bar), and the release of water at a pressure
of 1.8 – 2.0 bars.
The bleed valve on the expansion tank fitted to the race car is
permanently open.
The cooling water feed pipe 996.106.610.01 and return pipe
997.106.502.00 have different quick release ‘Henn-Couplings’ at each
end. These ‘Henn-Couplings’ have safety clips.
Engine side safety clip 996.106.802.10
Chassis side safety clip 996.106.802.11
These safety clips must not be swapped from chassis to engine
side and vice versa.
In addition to the part number, the safety clips can be distinguished by
the identification notches. The safety clips on the engine side have a
single notch and the safety clips on the chassis side have two notches.
An electronic cooling system filler specifically suited to the 997 GT3 Cup
can be purchased directly from Sobek.
