coolant air pocket? I just recently installed a new opti and im having trouble with air pockets. I've done all the usual basic stuff but is there something about lt1's that makes it tougher to bleed. This is my first ltx car so I am new to them. I have no heat and the temp gauge only sometimes goes up, and even the. It never goes higher than 160. Rite now it just sits at a 100.

My LT1 has two bleeder screws, but when I had air pockets my temp would spike up... then I'd turn the two screws til I saw coolant and my temp would drop back down to normal.

Most of the air is bled out when you fill the system with the bleeder screws open. I rarely have to do anything more than that. If your heater still does not work, it probably needs a flush. You should do this before you fill the system back up.

But in short open both bleeder screws, refill coolant, start and close bleeder screws. Once the car is warmed up you can open the bleeder screws again to make sure only coolant is flowing out. The link shbox provided explains it all in detail.

I have a question regarding the bleeder screws and this entire process. I have a Mezier water pump. I am pretty sure there is a pretty big air pocket in there. I don't have a thermostat. Can I just undo the bleeder screws, undo the top radiator hose and pour either water or fluid through that top radiator hose without having to drain the system. I can't get to the drain plugs on the side as they are behind a engine diaper and the headers and it is a pita to get to that. So can I do this the way I just described?
