27) Reconnect the vacuum line for the brake booster at
the intake and install the two 10mm bolts holding the
metal vacuum line in place.
28) Reinstall the air intake tube, PCV breather hose and
IAC hose.
29) Start engine. Run vehicle at idle with radiator cap
off (or with funnel attached) to bleed any remaining
air from the cooling system. Do this with the front of
the car still elevated on jack stands to help trapped
air make its way to the radiator filler neck. The new
upper hose will suddenly become warm to the touch
when the thermostat opens. Once this happens
any air trapped behind the thermostat will be pulled
through the hose into the radiator. Once the upper
hose becomes warm, install radiator cap. Check/reset
ignition timing to factory specs 10 deg BTDC. Timing
must be checked with all loads off, vehicle idling at
full operating temp, and check connector shorted
from TEN to GRD.
Timing must be set correctly or
severe engine damage may result!
Consult service
information if further information is required.
30) Test drive vehicle while closely monitoring
temperature and re-check for leaks. Allow engine to
fully cool down overnight and recheck that radiator
and overflow tank are full. Top off as necessary and
enjoy your cooler running Miata!
