Left Side Engine Compartment:  
 

Open engine cowling and check: Firewall fuel filter - check handle stowed Engine oil - check quantity and cap secured (ensure cap is seated and locking lever is locked in an aft direction) Check bilges of both engine compartments (fwd/aft) for foreign objects, leaks, and general security Check security of NACWS antenna cable connection. (Can see this real well from the right side plus see where the coax cable attaches to the firewall)

Make sure the oil cap is closed the right way.  The lever should always be pushed aft to lock down the cap.

 ENGINE GOUGE
 

• Bleed air valve-located at the 7 o’clock position just forward of the inlet screen.  Provides engine anti-stall characteristics at low engine speeds.
• Bleed air regulator valve-mounted on forward side of engine compartment wall, has big silver bleed air duct running into top of valve. Regulates bleed air into the cockpit.
•  Engine wash ring - silver ring runs over the top of the FOD screen, the tube is about the diameter of a bic pen
• Starter/Generator- white cylinder on top of accessory section with large green air cooling duct/tube attached to aft end of unit (check air duct for security)
•  Oil to fuel heat exchanger- grey box on top of accessory section, just above starter and to the right of the oil cap
• Air conditioning compressor-mounted on bracket, looks just like the one in your car (check the condition of the belt, can pull on this belt to turn compressor, but use caution not to get your fingers caught between the belt and pulley) As you pull belt listen for tinkling sound comming from the compressor section, these are the cold turbine blades moving around, that is ok.
• Engine driven fuel boost pump-dark grey, behind A/C compressor and below starter. Can see orange fuel lines attached to inlet and outlet.
• External oil scavenge pump- a lighter grey color than the fuel boost pump (mounted on same shaft) Can only see a portion of this pump.
• Ignitor box- silver box marked “Exciter”, just above the A/C compressor, has the two silver ignitor wires running out of it
• Fire detectors- left side on firewall is position no.2. Combustion chamber is no.3. Lower stbd side is no. 1  gouge for memory (LUC lower, upper, combustion chamber, and 1,2,and 3 respectively)
•  Condition lever cables-two silver cables coming out from top of firewall
• Environmental control cables- two black cables coming out of the firewall near the condition lever cables.  (One goes to bleed air regulator, the other goes to the jet pump located below the A/C compressor)
•  Muffler-stands vertical next to firewall (looks like it is covered with tin foil)
