Installing Coolant Regulator

Information 

Specifications for wrench sizes (a/f specifications) for screw heads are described as follows:

• Torx screws: (E..) for external Torx, (T..) for internal Torx. 
• Hexagon-head bolts (internal and external hexagon): Wrench size (a/f) 

Information 

• The coolant hoses must lock with an audible click when pushed into the plug-in couplings. 

Information 

• Check O-rings on the plug-in couplings and replace them if necessary. 
• Clean plug connection and coolant hoses before assembly. 
• Coat O-rings and coolant hoses with Kluber Plus Gel (Part No. 000.043.205.93). 
• Remove stoppers before fitting the coolant lines and hoses.
