Draining
 
 
WHEN DRAIN ENGINE COOLANT USING DRAIN HOSE
warning
  • Never remove reservoir tank cap when engine is hot. Serious burns may occur from high-pressure engine coolant escaping from radiator.
  • Wrap a thick cloth around the reservoir tank cap. Slowly turn it a quarter of a turn to release built-up pressure. Then turn it all the way.
 
 
1. Remove engine under cover and engine under cover front. Refer toRemoval and Installation .
2. Connect drain hose.
  • Use a genera-purpose hose with the dimensions show in the figure.
    A: φ 8.5 mm (0.335 in)
    B: 150 mm (5.91 in)
3. Open radiator drain cock at the bottom of radiator, and then remove reservoir tank cap.

caution
  • Perform this step when engine is cold.
  • Draining coolant from the radiator, should make sure that the drain plug is pointed downwards.
  • When draining all of engine coolant in the system, open water drain plugs on cylinder block. Refer to Setting.
4. Remove reservoir tank if necessary, and drain engine coolant and clean reservoir tank before installing.
5. Check drained engine coolant for contaminants such as rust, corrosion or discoloration. If contaminated, flush the engine cooling system. Refer to Flushing.
6. Disconnect drain hose.
 
 
WHEN DRAIN ENGINE COOLANT USING TEMPORARY PIPE
 
 
1. When draining coolant, follow the instructions below and create a temporary pipe to prevent from splashing.
(1) Prepare soft plastic board (e.g. plastic file folder) and roll up the plastic board.
AApprox. 295 mm (11.61 in)BApprox. 210 mm (8.27 in)CApprox. 145 mm (5.71 in)
2. Check that the length of temporary pipe (A) approx. 145 mm (5.71 in).
3. Remove engine under cover front. Refer to Removal and Installation.
4. Align the plastic board with the outside diameter of drain guide and fix with tape.
5. Install temporary pipe (A) to drain guide.
