Engine startup & Break-in procedure
Congratulations! You have purchased the finest, most reliable remanufactured engine on the
market, engineered and built to provide you with miles of trouble-free motoring.
What comes next is in your hands – ignition! Please follow our guidelines in
this critical step of starting your engine and takingit to operational level. Doing so will help
minimize headaches, heartaches,and financial loss. How you prep, start, adjust,and driveand
perform maintenance will determine largely the smoothness, efficiency, power and longevity
new S&J engine. Read our recommendations thoroughly before proceeding.
You’ve Got This!
Intake and exhaust manifolds
We recommend strongly to use all new peripherals components, using new fasteners
and gaskets per OEM manufacturers recommendation. Make certain that the intake
manifold is in place: new gaskets and fasteners secured exactly according to
your engine’s specific tightening order and torque readings. Same with the
exhaust manifolds (or headers). Some engines (i.e.,certain Mopar engines)
require a new, OEM intake manifold: failing to comply to this requirement can
void your warranty.
Never attempt to start the engine without exhaust manifolds in proper place!
Use only new drive belts for your engine. This includes water pump, fan, air
conditioning, and any ancillary items. Verify that all are properly installed,
aligned, and tensioned.
Ensure that the engine cooling system is fully functional and is filled with the
prescribed amount of coolant mixture. We recommend strongly new radiator, water
pump and hoses.
As your engine is being started for the first time leave the radiator cap off or
use a vented cap, as there will likely be trapped air. We recommend filling the
cooling system several hours before startup to allow some of the air to travel
to the surface. During the initial startup, air will likely be exiting the
cooling passages. Watch for this and the engine temperature readings that may
fluctuate during the process.
Use only new coil packs, injectors, sparkplugs, sparkplug wires, distributors,
etc. for the engine ignition system. Ensure that all components are matched to
your engine type and application before starting.
Use the oil supplied with your engine. It is designed specifically for the
break-in phase. Use only the finest oil filter. Your new engine will be
seatingduring the initial break-in phase, and residual machining material will
be entering the oil system. Oil filter choice and performance is essential. When
installing the oil filter, fill with oil at least halfway to help prevent
starvation and engine metal-to-metal contact of internal moving parts.
It is vital to prime your engine with oil before starting, as the engine is
“dry.” Internal surfaces and oil galleys require an adequate amount of lubricant
before ignition. The oil pump and oil galleys (passageways) must be filled and
pressurized to prevent oil starvation and metal-to-metal contact, a primary
source of engine damage and failure.
Set initial timing for first ignition as per factory recommendations. Given the
vast variety of engine configurations and internals, determine your preset by
referring to OEM specifications and recommendations.
