Where considered necessary, some hose connections have an indication mark to ensure correct orientation of the hose when being fitted.
All joints use spring-band clips, except small pipes on the bleed system joints - which use cobra clips. The heater feed and return hoses use quick-connection unions
Supply and return hoses for the heater are located between the cylinder banks.
A connection on the rear of the A-bank provides coolant supply for the electronic throttle and the EGR valve (where fitted). The outlet from the electronic throttle connects to the return hose from the heater.
