-
Step3. Drain the coolant into a bucket through the drain valve. As shown in the following figure. (1 5gallon bucked)
-
Step4. Remove the sealing plate at the bottom of the radiator. As shown in the following figure. (18mm)
-
Step 5. Open the engine hood and remove it. As shown in the following figure. (Remove cotter pins with plyers) Lay hood back.
-
Step 6. Remove the original pedal. As shown in the following figure.(18mm)
-
Step 7. Remove the radiator ends of the two air ducts from the engine and place them aside to avoid affecting the next operation. As shown in the following figure. (screwdriver or 7mm for hose clamps)
-
Step 8. Remove the plate from the front half of the original fan guard. As shown in the following figure.(16mm)
-
Step 9. Cut the drainage hose from the hole at the bottom of the platform in the middle of the vertical section and remove a 1 inch length in the middle 2 1/2 inches from the 90. As shown in the following figure. (Razor knife or hose cutter)
-
Step 10. Install the steel pipe 31G0277 into the water pipe and install the pipe clamps 09C2297 at both ends. As shown in the following figure.
-
Step 11. Place water pipe 10G2111. Connect the lower end of the water pipe to the small end of the steel pipe in the previous step and install the clamp 09C2294. The pipeline passes through the outer side of two hydraulic oil pipes and secure the pipes with 15B0175 at the 3 red circles in the figure. As shown in the following figure.
-
Step 12. Install a new fan guard board 21G5833. As shown in the following figure. (Remove spacer & clamp, use bolt from front of radiator to replace from step 19)
-
Step 13. Fix the water pipe to the new fan cover with pipe clamp 09C2716, washer 06B0472, and bolt 00B1085, while restoring the installation bolts of the hydraulic pipe. As shown in the following figure. (Need short ratchet and short 16mm, leave 10 1/2inches of hose past clamp)
-
Step 14. Block the left water outlet of the radiator with a rubber sleeve (84A7902) and clamp (17G0116). As shown in the following figure.
-
Step 15. Place the expansion tank 05D3256 in the pre-installation position, and install the small end of the discharge port (throttle pipe) 37A7963 into the expansion tank connection interface, as shown in the following figure.
-
Step 16. Install one end of water pipe 32A9509 onto the discharge port (throttling pipe) 37A7963 and insert it into the expansion tank joint 20mm. Connect the other end to the right water outlet of the radiator and install the clamps 17G0116 on both ends. The clamp at the expansion tank end is clamped on the expansion tank joint, and the rubber hose is exposed by 3mm, as shown in the following figure.
-
Step 17. Remove the clamp of the radiator outlet overflow pipe. Remove the replacement radiator and expansion tank pressure cap behind the overflow pipe. Use the prepared plug (84A8183) and clamp (17G0116) to block the overflow port of the radiator, as shown in the following figure.
-
Step 18. Remove the 2 pipe clamps of the overflow pipe above the intercooler, as shown in the following figure.(Use one blot in Fig 13)
-
Step 19. Puncture the sealing sponge with a screwdriver on the top of the hydraulic oil radiator at a distance of 50mm from the pipe clamp edge and the radiator frame, as shown in the following figure. It is best to drill diagonally upwards, as shown by the red arrow in the figure below.
-
Step 20. Pass the overflow pipe through the same perforated sponge hole, connect the overflow pipe to the overflow port of the expansion tank, and tighten it with a 17G0116 clamp, as shown in the following figure.
-
Step 21. Install a new pedal 41D3572. Fix the expansion tank 05D3256 to the pedal 41D3572 with bolts, as shown in the following figure.
-
Step 22. Connect the upper end of the water pipe to the water outlet at the bottom of the expansion tank with clamp 09C2294. As shown in the following figure.
-
Step 23. Restore the two exhaust pipes of the engine. Cut the appropriate length according to the requirements and install it onto the air tank with a clamp. As shown in the following figure. (Left hose "Big" cut 8inches off- Right hose "small" cut 6 1/2inches off)
-
Step 24. Fix the overflow pipe to the reserved hole on the triangular rib plate of the pedal with a tie, as shown in the following figure.
-
Step 25.Labeling. The coolant label 16G1420 is moved from the vicinity of the water dispersion filling cap to the position shown in the new pedal. Adjust the original safety label 74A3161 to the position shown in the new pedal diagram, as shown in the following figure.
-
Step 26.After completing the above steps, please carefully inspect each hose and clamp component. The gap between the water hose and the fan should be over 25mm, and the gap during vibration should not be less than 20mm.
