WARNING:Hot, pressurized coolant can cause injury by scalding.

  1. Remove the radiator cap to relieve any residual pressure in the radiator.

NOTE: When installing the new clamp, the original will remain in place. The new clamp should be positioned between the existing clamp and the radiator outlet flange. Take care not to overlap the clamps.

  1. Reposition the original upper radiator hose clamp forward toward the radiator if necessary to prevent clamp overlapping.
  2. Open the new clamp and place it over the radiator hose along side of the original spring clamp (do not discard the old spring style clamp). The hex head of the clamp should be facing up and be oriented on the core side of the radiator as shown in (Fig. 21).

Fig. 21 Radiator Hose Clamp OrientationFig. 21 Radiator Hose Clamp Orientation

 

NOTE: The new clamp will have a torque limiting head. The head will break free once proper torque of 3 N·m (26 in. lbs.) is achieved. Care must be taken to ensure the socket used only engages the head of the bolt to prevent over tightening the clamp.

  1. Using a 7 mm shallow socket and swivel, tighten the new clamp until the torque limiting head breaks free as shown in (Fig. 22).
