SOURCE: Is there a bleeder valve

Should be one on the bottom of the radiator, but some times there isn't if there isn't one there you will just have to pull the bottom radiator hose. Unless your working on the top side of the coolant system then you could pull the top hose most the time to let out enough coolant to get done what you have to do. Some times it takes a lot of moping though. Your choice, depending on what your trying to do to your coolant system.

How do you get the air out of a coolant system in a 2007 Buick Lucerne ?

In 2007 the Buick Lucerne was equipped with 2 engine options. 3.8 Liter OHV V6 and the Northstar 4.6 Liter V8.

Was the cooling system recently opened? What was serviced?

The 3.8 has a 7mm bleeder screw on the top of the thermostat housing. A funnel in the radiator is helpful to bleed the air. You will notice the upper radiator hose curves to a higher elevation than the bleeder screw. Manipulation of the hose by hand may be needed to get the air out. I recommend and use a cooling system funnel to help. It minimizes mess as well. ( ) There are other brands available as well.

I do not recall if the Northstar V8 has a bleeder on all models, but some do have a similar bleeder screw. Be sure the system is filled initially and manipulate the hoses up and down as well as squeeze them to get air moving. The Northstar water pump is on the back side of the engine driven by the camshaft. The upper hose runs along the front of the engine bay and connects to the radiator at the top on the passenger side of the engine bay.

For both vehicles, fill as much as possible cold. Start and idle. As the temperature increases, I recommend occasionally revving the engine to between 1500 and 2000 RPM to fill heater core and move coolant with a little more force.

Where are the bleeder screws for coolant system?

The bleeder screw is on the passenger side front of engine. It is a small 1/4" square head bleeder bolt. Turn it counter clockwise making sure coolant level is full. After coolant is coming out then tighten back down.

Toyota Corrolla 1995. The heater does not work, I replaced the thermostat and have put a lot of antifreeze.

bleed cooling system, probably there is air trapped in the heater core preventing warm coolant to circulate into the heater core. try this
1 open radiator cap fill coolant and put heater in hi heat
2 start engine and wait until you see the coolant start to circulate
3 squeeze hose several times watching if coolant volume decrease
4 add more coolant and repeat 3 until coolant volume stays same or start overflowing.
5 check if heater giving off warm air or repeat 3 and 4 until warm air blows on heater.
or find the coolant bleeder screw, do 1 and 2
open bleeder screw until coolant come out, do this several times until no air comes out when opening bleeder screw, fill coolant in radiator.

How do I bleed the air out of the coolant on a 2000 Monte Carlo LS 3.4L?

Look for a bleeder screw at the highest point of the coolant system, it is usually located on the thermostat housing. Once located open screw with engine off and cool, and pour coolant into the coolant resevoir/ radiator until steady stream of coolant starts to come out of bleeder screw.

2001 Cadillac Deville coolant bleed screw Location??

I had the same problem with my 2001 Cadillac Deville, like you I had replaced literally everything thermostat, water pump, radiator, temperature sensor, reservoir and cap, hoses etc....I didnt have any leakage. I was told I had air in my coolant system. After a lot of research and running across the right mechanic I was able to locate the bleeder and remove the air from my lines. No problem since. The bleeder is located on yhe left side of the radiator on the crossover, mines was sideways..Hope this helps someone before they spend money for new head gasket problems..Try this it helped me....
