Systems Description Model G58

ENGINE ICE PROTECTION

Engine ice protection consists of electrothermal fuel vent heat-
ers controlled by a switch on the left subpanel, and an auto-
matic alternate air induction system.
The only significant ice accumulation is impact ice on the inlet
scoop and filter. Should the induction air scoop or filter become
clogged with ice, a spring-loaded door on the firewall will open
automatically, and the induction system will operate on alter-
nate air.

ENGINE LUBRICATION

The engine oil system for each engine is the full pressure, wet
sump type, with a full flow, integrally mounted oil filter and has
a 12-quart capacity. Oil operating temperatures are controlled
by an automatic thermostat bypass control. The bypass control
will limit oil flow through the oil cooler when operating tempera-
tures are below normal and will permit the oil to bypass the
cooler if it should become blocked.
The oil system may be checked through access doors in the
engine cowling. A calibrated dipstick attached to the filler cap
indicates the oil level. Due to the canted position of the
engines, the dipsticks are calibrated for either right or left
engines and are not interchangeable.
The oil grades listed in Section 8, HANDLING, SERVICING &
MAINTENANCE are general recommendations only, and will
vary with individual circumstances. The determining factor for
choosing the correct grade of oil is the average ambient tem-
perature.
