DAILY MAINTENANCE
2.1.
CONTROL OF COOLANT LEVEL
The coolant level must be checked daily. It is necessary to ensure that there aren't air or steam bubbles in the
system. In that case the system must be purged by hand or automatic vent valves must be installed in the top of
the circuit.
The quality of the cooling water must comply with IO-C-M-20-001, which specifies not only the water quality but
recommends the percentage of glycol to be used.
NEVER USE DIRTY, HARD OR SALT WATER. COOLANT NOT ONLY PRESERVES ENGINE AGAINST
FREEZING, BUT ALSO PRESERVES ENGINE AGAINST CORROSION AND OXIDATION. SEE
IO-C-M-20-001.
2.2.
CONTROL OF OIL LEVEL
Check the engine oil level every day under identical conditions. This is to be done with the engine idling, after
running for several minutes.
The oil level should never be below the lower indicator mark, nor above the high limit on the dipstick.
Note: If the engine has crankcase gases recirculation system, the oil level on the dipstick could be erroneous
because the pressure in the crankcase is not at atmospheric pressure. Therefore, the oil level must be checked
when crankcase pressure is at atmospheric pressure or the reading must be done in the devices not influenced
by these pressure differences: lubrication oil level indicator or oil level regulator (with the filling valve closed).
2.3.
DAILY RECORDING OF THE ENGINE DATA
It is necessary to record pressures, temperatures, levels, energy outputs... in order to be able to detect possible
engine operation failures by analysing the evolution of the aforementioned parameter values.
Note: Daily records may help you to solve performance problems before they arise, because of that, it is
recommendable to record a high number of parameters of engine performance.
2.4.
CLEANING OF THE ENGINE
Several reasons make it desirable to keep the exterior of the engine clean. Dirt from the outside can be drawn
into the intake filters. Further, exterior dirt can get into the engine during normal maintenance in cylinder heads,
crankcase...
A number of products for cleaning the engine exterior can be used, such as pressurized steam or degreasing
agents. It is necessary to be extremely careful with the electrical components of the engine.
2.5.
CLEAN AND KEEP WATCH OVER ELECTRICAL CONNECTORS
Clean the electrical connectors if necessary, but before be sure that there is no tension on them.
