Hey guys, I'm just finshed with installing a new water pump and intake on the camaro. When I refill the coolant is there any tricks or ways I should do it to avoid any air pockets?
thanks in advance!

There are no tricks involved!....Just make sure that the lower radiator hose is tightened good as this is where air could suck in!....Merely top up the radiator slowly until it will hold no more....Keep in mind that the level will go down after running the engine so just recheck and fill to the proper level.

take the thermostat housing off and fill the radiator until the intake is full right up to where the thermostat goes. put the thermostat and housing back on and hook up the upper hose. fill the rad to the top..
there ya go- no bubbles.

I have never had a air lock...excep whenb I mounted a LPG mixer above radiator height, and u dont have one of those...
Turn heater on, Fill up as above, then squeeze/pump the top hose a bit, top up, and again
Fire up, keep rpms up a little, u will ee the coolant hitting the wall thru the neck, keep topped, then put the cap on before things get hot turn
The excees will overflow eventually stablizing correct height

That's the way I always do it - I modified a funnel to simplify it; cut off the end so it stands up by itself in the intake, and drilled holes around the edge so I can see the coolant level rising as it's added so I don't overfill and make a mess. :)
