    Default No pressure in the cooling system. Is that right?

    question: after having a lot of trouble with the cooling system, (too much pressure because the cylinder head was cracked, so all the hoses started leaking) i fixed the head, changed water pump, hoses, thermostat, and now its running ok, temp is always in the middle and a bit less. But the system has noo pressure at all. Is that a bad sign? My car is really running fine, so i guess there is no problem.
    What do you think about this?
    Thanks

    if it's cool outside and the system is in good shape it just may not be building pressure, which is not a bad thing in and of itself, or you could have a bad cap and it's bleeding it out
