just flushed system and replaced coolant. seems to be operating ok. should i gamble and play with the 2 bleeder valves OR =- leave well enough alone ?? what would you do ?

It's not uncommon to get lucky and not need to bleed the system. Keep a close eye on the temp guage, if it starts to fluctuate or rise suddenly, then you have air in the system that needs to be bled out.

Yes, defenatly crack them open and listen for the hissssss of air escaping. and turn on the heat and see if it blows warm just to make sure that you have coolant circulating through the heater core.
