16.5 Draining the liquid cooling circuit

In case of part replacement, consider only draining that part of the circuit which contains the defect part. E.g.
in case of pump replacement; it is preferred to bypass the engine circuit. This to exclude the engine from the
problem.
Necessary tools
• Half a meter of plastic tube with male valved fitting.
• Half a meter of plastic tube with female valved fitting.
• Syringe connected with short tube with male valved fitting.
• Empty bottle with a volume of 1 liter.
• Cloths.
How to drain the liquid cooling circuit ?
1. Interrupt the liquid cooling circuit by uncoupling the valved fitting at the heat exchanger.
Tip: Sometimes a little cooling liquid will be spilled. Wrap a small cloth around the valved fitting while uncoupling to absorb
the spilled cooling liquid.

2. Insert the plastic tube, which contains a female valved fitting, into an empty bottle and then couple the female valved fitting with
the exit side of the cooling circuit.
Note: Circuit is pressurized, so first insert tube end into empty bottle.
