Abstract: The cooling system is one of the important things but also the most ignored thing when it comes to maintenances. Very
few people are known about how to keep the maintain the coolant properly or when to replace the coolant. As distilled water is
not readily available everywhere people usually top up their coolant with tap water which will cause deposition of mineral which
may damage the radiator.
These minerals are responsible for the rusting of internal components of the engine. A survey shows that majority of the people
don’t check their coolant. Therefore, we intend to make a system that will display the condition of the coolant. The system will be
IR based which will indicate the condition of the coolant based of its color. A different threshold is set for a different color. Some
of the previous research use electrodes to check the condition of the coolant but it could only detect the rusty coolant, not the
degraded one.
The degraded coolant will not absorb as much heat as the new coolant. The
