(3C-T)
1. Drain the coolant.
2. Remove the timing belt.
3. Remove the toothed pulley of the injection pump and injection pump drive.
4. Turn out bolts and remove the pump of a cooling liquid.
Checking the coolant pump
1. Visually check that there are no coolant leaks from the connections and air hole.
2. Rotate the pulley and check that the pump shaft rotates easily and silently. If there is a problem, replace the pump assembly.
