Radiator Bleed Hose Deformation

MODEL AFFECTED VEHICLES

Range Rover V8 All V8 derivatives between LH 650660 to LH 650889 and Discovery V8 LJ 091608 to-LJ 092487

DETAIL

A preformed nylon bleed hose was introduced onto the V8 derivative which replaced the existing rubber hose. It has been found that under normal engine operating conditions the hose can deform in the area of the preformed bends. To overcome this condition the previous part and routing was re-introduced. In instances where a bleed hose has deformed fit the previous part taking note of the illustrations overleaf to determine revised routing and securing arrangement.

ACTION REQUIRED

If deformation of the bleed hose is noted at 1000 mile service or during normal routine servicing, replace the nylon hose with the previous part.

PARTS INFORMATION

Replace ESR 3221 nylon bleed hose with ERR 0330 rubber bleed hose. 568680 Tie wrap (2 off)

PROCEDURE

Release the hose clips at the radiator and plenum chamber. Remove the hose from the plenum chamber first and replace with the new hose ensuring that the hose removed is kept above the level of the radiator to prevent loss of coolant. Refer to the illustration overleaf for the routing of the new hose and using tie wraps secure the hose to the existing hoses shown. Note: Do not pull the tie wrap too tight. Remove the nylon hose from the radiator and quickly replace with the new hose to prevent loss of coolant. Tighten the hose clips to 2.5 Nm using a torque screw driver. Run the engine to ensure that the hose clips are secure and no leaks are evident.
