It is called an Expansion Tank

You keep it topped up with water and when the cooling system wants some water it draws it down from there.

If the cooling system is too full it pumps the water back into the expansion tank

There should be two marks on the tank Min & Max , the water level should be on Max at all times

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.

Temperature guage goes hot immediately upon starting 98 buick regal

Make sure you billed the system , this engine have two bleeder valves one on front above the front valve cover and the other one on the driver side on the top radiator hose near Engine , it should a 7mm add antifreeze while those bleeders are open , also check that you don't have a blown intake gasket or Head gasket , but as far is the temp goes up quick , it's because it has lots of Air in the cooling system and it must be bled . Becareful full as antifreeze may be extremely hot during this process . Hope this help

2004 2.7 L leaking water around the top of the engine coolant air bleeder

Replace the coolant air bleeder, front and center top of the engine. Remove the 10mm bolts holding the air intake down, prop it a a few inches, take the four bolts out and the two bolts holding the top radiator hose to it, polish ip the top of the motor where the pice sits bolt it back together. It took me about ten minutes to put in the new one. The part from advanced auto was 39 bucks, comes with a new o ring for the top hose, it is a piece of cake.

1999 Chrysler 300m heater won't get hot fan blows but doesn't heat

Is there enough anti-freeze in the system?
If so perhaps the system needs bleeding.
On the front of the engine, on top near the big upper hose goose neck and nestled between the runners of the intake manifold is a small nipple that looks like a brake bleeder (10MM). This is a cooling system bleeder, a close cousin to the brake bleeder. When opened it will purge the system of air- likely the culpret you are experiencing. on a cold or just warm engine, this can be slightly opened with a wrench and the air can be "Burped" out. Attach a 1/4" clear hose to the nipple and open the bleeder until you see all the air has left the manifold. (Run the hose into a bucket and dispose of the used anti-freeze properly.)
if that doesn't do it, maybe the thermostat is stuck in the open position. Replace it with a cold engine and use a new gasket each time.
If all else fails, the heater core may be plugged.

My coolant resevoir is full but top coolant hose is empty. Is there a bleeder system?

Here is a basic description of cooling system, the top hose going to engine is the supply hose the bottom hose is the return hose. On your overflow coolant reservoir there is a lower cold level mark and a hot level mark above it also there is an overflow drain spout several inches above hot level mark to relieve pressure if system is overfilled. As to a bleeder system, bleeders purge air from a system to allowed it to become primed (pressure built up) generally on hydraulic systems like brakes or pneumatic systems like a diaphram pump for example. the only drain available is the petcock valve at the bottom of the radiator used to drain coolant. Now to your top hose being empty, you can remove top hose to engine have a garden hose running into radiator and if radiator cores are not stopped up water should flow freely from hose if not radiator is clogged. If you have water flow now you can pressure test system it should hold between 15-18lbs pressure constantly otherwise check all hoses/clamps etc (if leaks were present before replace faulty component/s) your vehicles water pump circulates coolant and is what pressurizes cooling system. A faulty thermostat will also restrict coolant from entering the engines coolant passageways if it doesn't open and your vehicle would overheat soon after, but you should still have coolant in upper hose when engine is running regardless. If you can add other info like your vehicle is running hot or coolant light coming on I can narrow it down for you.

Yr 2000, 300m 3.5......No heat. has antifreeze and just put in new thermostat. what the hell is wrong ? Freezing in Indiana

Just for everyone's edification: There is a cooling system BLEEDER on top of the intake manifold in front of, and between the runners of the fuel injection plenum- that big, black, spidery looking thing on top of the engine. It is a 10MM bleeder that looks just like a brake bleeder. turn it counter-clockwise until all the air is gone and fluid runs freely. That should do it. Sorry dadhoosierg had to freeze to death before he got his answer... but it is good advice for the living. :)

Changing a thermastat on a 2003 Caravan

the 1993 caravan had two engines offered a 2.5L 4cylinder and a 3.3L v6........on the 2.5L the thermostat is located on the front of the cylinder head were the top radiator hose attach's.
remove the top hose were it attach's to the thermostat housing and the remove the thermostat housing and lift out the thermostat and replace with the new one making sure the spring on the thermostat is facing the engine replace the thermostat housing and top radiator hose and remove the bleeder screw from the top of the thermostat housing and fill radiator with new antifreeze. when you see antifreeze coming out the bleeder hole replace the bleeder screw.

The 3.3L v6 also has the thermostat at the front of the cylinder head were the top radiator hose attach's the thermostat housing the procher is the same except for bleeding the radiator, to bleed the cooling system remove the coolant temp. sensor it is located just below the thermostat housing and fill radiator with new antifreeze until the antifreeze starts coming out the coolent tempt sensor hole them reinstall the sensor and top of radiator.........GOOD LUCK

Iv recently had the right side engine head changed n once i got my truck back the heater started blowing cold air

Mechanics probably didn't get all the air out of the cooling system. Take the radiator cap off and start the engine. Turn the heater on high and let the car warm up until the thermostat opens and coolant is flowing in the radiator. Keep the radiator full as level may begin dropping. Let it run a while keeping it full and look for any bleeder ports on the hoses or the housings where the hoses attach. Break any bleeders open to let air out. Top off the radiator and put the cap on. You should have heat. Let me know if you don't.

On the 2.2 engine thermostate

It's going to be at the back of the engine where the hose attaches, also most Honda's will have a bleeder valve a little bit back from the thermostat housing, make sure you bleed the air out of the cooling system or it will over heat on you, just open the valve I think it's a 12mm socket to open it and close it when no more air come's out.
