Verify that both the camshaft and crankshaft alignment marks are perfectly positioned.
If you are currently rebuilding your engine, a detailed manual is the only way to ensure success.
Fuel filler cap open/evap leak (highly sensitive on e-POWER vehicles to prevent volatile organic compounds from degrading fuel quality during periods of low engine use). 6. Safety Warnings for e-POWER Vehicles
The E13 engine thrives on regular, simple maintenance. A typical service schedule will include:
Avoid touching, cutting, or servicing any cables wrapped in orange conduits unless the high-voltage system has been officially shut down.
Do not just pull the fuel pump fuse. The manual specifies: run engine, disconnect high-pressure pump connector, let engine stall, then crank for 3 seconds.
Parts such as the timing belt tensioner are readily available for vehicles equipped with this engine.
