4. Insert the main suction tube into the radiator or expansion tank until it reaches the bottom.
5. Insert the rubber plug of the main suction tube into the reservoir adapter, and then insert the adapter into
the pour spout on the top of the reservoir. Ensure the tube connections are tight to prevent leakage.
6. Extract the used coolant by pumping the evacuator handle several times to create a vacuum. Once
the coolant begins to ow into the reservoir, continue to operate the pump until all the coolant has been
drained from the radiator or expansion tank. Note: Due to varying engine uid capacities, if the coolant
system capacity exceeds 7.7 Quarts/7.3 liters, it may be necessary to empty the uid reservoir before
resuming the extraction process.
7. Remove the reservoir adapter from the reservoir, pour the used coolant from the reservoir into a suitable
container, then dispose of the coolant in an appropriate manner.
8. Rinse the evacuator reservoir, pump, adapter, and tubes with clean solvent or engine degreaser, and allow
them to dry thoroughly.
9. Rell the radiator or coolant reservoir with new coolant in accordance with a proper vehicle maintenance
guide.
Extracting brake uid from the master cylinder
1. Properly park the vehicle on level ground and turn the engine off.
2. Clean the exterior of the master cylinder and master cylinder cap to prevent dirt from entering the master
cylinder when the cap is removed.
3. Remove the cap from the master cylinder reservoir.
4. Insert the rubber plug of the main suction tube into the reservoir adapter, and then insert the adapter into
the pour spout on the top of the reservoir. Ensure the tube connections are tight to prevent leakage.
5. Insert the main suction tube into the master cylinder.
6. Extract the used brake uid by pumping the evacuator handle several times to create a vacuum. Once the
uid begins to ow into the reservoir, continue to operate the pump until all the uid has been drained from
the master cylinder.
7. Remove the reservoir adapter from the reservoir, pour the used brake uid from the reservoir into a suitable
container, then dispose of the uid in an appropriate manner.
8. Rinse the evacuator reservoir, pump, adapter, and tubes with clean solvent or engine degreaser, and allow
them to dry thoroughly.
9. After all repairs are completed, rell the brake system in accordance with a proper vehicle maintenance
guide.
Extracting power steering uid from the power steering uid reservoir
1. Properly park the vehicle on level ground and turn the engine off.
2. Clean the exterior of the power steering uid reservoir to prevent dirt from entering the reservoir when the
cap is removed.
3. Remove the cap from the power steering uid reservoir.
4. Insert the rubber plug of the main suction tube into the reservoir adapter, and then insert the adapter into
the pour spout on the top of the reservoir. Ensure the tube connections are tight to prevent leakage.
5. Insert the main suction tube into the power steering uid reservoir.
6. Extract the used power steering uid by pumping the evacuator handle several times to create a vacuum.
Once the uid begins to ow into the reservoir, continue to operate the pump until all the uid has been
drained from the power steering uid reservoir.
7. Remove the reservoir adapter from the evacuator reservoir, pour the used power steering uid from the
reservoir into a suitable container, then dispose of the uid in an appropriate manner.
8. Rinse the evacuator reservoir, pump, adapter, and tubes with clean solvent or engine degreaser, and allow
them to dry thoroughly.
9. Rell the power steering system with new uid in accordance with a proper vehicle maintenance guide.
Prior to inserting the extraction tube into the master cylinder reservoir, be sure that the extraction tube is
clean and free of any other types of uid. Failure to do so could result in contamination of the brake uid in
the hydraulic system and cause potential brake failure.
