Hello,

I've purchased new coolant tank for my Falcon EA 1989 as the old
one cracked and was leaking. There are two inlets to the tank: one
from the thermostat, and one from radiator. Is it normal that the
first one is blocked, which looks like factory seal (clear, not
drilled plastic)? I've run the engine idle for a while with the
hose loose and there is no coolant flowing through it back to the
tank. After installation of new tank, coolant level is higher than
before. Why is that? If it's air in the system, how can I get rid
of it?

Cheers!
Rado

Hi Rado, yes that's normal. Some EA's only had one hose (thermostat one) and
other's I think Series II had both.

Nothing will flow through as it's blocked off by plastic casting, to enable
the hole to be used (if you require) just drill the hole through and blow
the plastic residue away.

To bleed air from the system with cap screwed on just one notch, run the car
from a cold start to warm idle with heater on full and idling about 2000rpm
until the thermostat opens up or at least 5 minutes, then check coolant
level and tighten cap. (this is marked on the bottle anyway)

If the level is at max (marked on the side of the bottle) then it's fine.
