Vacuum hoses

V6 Vacuum Hoses
    With the V6 having numerous vacuum hoses, leak/constriction/incorrect-connection can make problems difficult to locate. Leaks cause a rough idle stalling

    Replacement of vacuum hoses requires approximately 5 metres of hose (EGR Valve, EGR Vent, EGR Vacuum, VRIS1, VRIS2, Purge Control, PRC, Cruise-Control, Fuel Pressure Regulator and Airbox). Silicone hose is available in various colours for location identification and tolerates far higher temperatures. The size required is 3mm bore and 2mm wall.

Replacing Hoses
    Replace hoses one at a time by twisting them off, pulling will break the plastic fittings on solenoids particularly at the rear of the engine. Verify the hose from the EGR solenoid down to the EGR valve on the back of the transmission area has not baked dry & split - these are subject to radiant exhaust heat.
