Antifreeze and Engine Coolant
All internal combustion engines generate heat. To regulate the temperature of the engine, an engine cooling system, usually a water-cooled system, removes the heat. Antifreeze liquid solutions are added to prevent ice build-up in these systems at cooler temperatures.

How do you bleed all of the air out of the cooling system on a 1995 Pontiac Grand Am with a 3.1?
on the side of the thermostat housing there is a small screw with the motor is running make sure the heater is on loosen the screw let the water run until you see a steady flow then tighten back up.
I disagree with the previous poster. The cooling system is bled by loosening the screw on the metal pipe just behind the water pump housing. The pipe goes upward off the housing and has a bleed screw on the end of it.
To Bleed the cooling system, turn the heater to full hot and open the screw and add coolant to the resevior until you get a bubble free flow of coolant from the bleed screw. At this point the system is bled and just tighten the screw.
How do you get an air lock out of your cooling system?
COOLING SYSTEM OF WHAT ???????????????????????
Most auto parts stores sell cooling flushing kits. Get one follow the directions and it should take the air out of the system. You must remember that your heater is part of the cooling system as well as the cooling for your transmission.
Does oil travel thru a radiator for cooling?
No, oil does not typically travel through a radiator for cooling. Instead, radiators use coolant, usually a mixture of water and antifreeze, to dissipate heat from the engine. In some specific applications, like in oil coolers, oil may pass through a separate cooling unit designed to lower its temperature. However, standard automotive radiators primarily cool the engine coolant, not the oil directly.
This is when the engine coolant ( which may include anti-freeze, anti-corrosion, anti-boil and other fluids ) is drained from the radiator, hoses, pump, engine block etc and the system is flushed clean with water (which may contain degreasers, cleansers, etc. ). After that, the fresh coolant with the new additives are put into the system.
The usual reason for doing this is to clear blockages from the small radiator tubes and the sludge and dirt that may have been deposited in the slower circulating areas of the engine.
What part of the engine will coolant boil first?
The cylinder head
The cylinder head area is the area where coolant will boil first if coolant is present. The area directly above the combustion chamber will get hot first, which is the bottom area of the cylinder head. The old saying that heat rises is still true. Heated coolant will usually exit the upper radiator hose to the radiator and as coolant is cooled in the radiator, it will circulate down into the block where it will be heated again to repeat the cycle. The coolant pump present in most engines just helps this natural cycle.
What should the pH be in radiator coolant?
The green antifreeze brand that I use in my vehicle mixed 50 / 50 with distilled water
has a PH of around ( 10 ) when it's new . Since anything below ( 7 PH ) is acidic
I have never let it drop below ( 8 )
Where is the coolant reservoir in a Lincoln ls?
The ENGINE coolant reservoir is on the drivers side of the engine compartment
next to the firewall
How do you check liquid cooled system for serviceability?
To check a liquid-cooled system for serviceability, first inspect the coolant level in the reservoir and check for leaks in hoses, connections, and the radiator. Next, ensure that the coolant is free of contaminants and has the correct mixture of antifreeze and water. Additionally, verify that the cooling fans and pump are functioning properly by observing their operation during system use. Finally, check for any unusual noises or temperature fluctuations that may indicate underlying issues.
What kind of plastic are radiator coolant lines made of?
Radiator coolant lines are typically made from high-temperature resistant plastics, such as nylon or polypropylene. These materials are chosen for their durability, chemical resistance, and ability to withstand the heat and pressure of the cooling system. Additionally, some coolant hoses may incorporate reinforced layers or be made from rubber compounds to enhance flexibility and resistance to wear.
How do you bleed the cooling system on a 4.6 liter north star engine?
The Northstar engine is a self purging engine. It requires no bleeding procedure.
How much antifreeze will kill a human accidentally ingested?
2 to 4 ozs. by comparison 1teaspoon can kill a cat.
No, antifreeze is green or pink. If your antifreeze is brown (its rust) you to flush and clean your cooling/heating system. No, antifreeze is green or pink. If your antifreeze is brown (its rust) you to flush and clean your cooling/heating system.
so the back heat also always blows cold every day we go blead the coolant system and we get air out but i mean how much air could their possibly be in there any other suggestions on what could be wrong?
Where is the sensor located for a 95 Chevy lumina for low coolant light?
location is on passenger side radiator , best view of sensor is done by removing headlamp assembly on passenger side. it is approximately 4-6 inches below radiator filler neck
Why does your fuel pump leak water?
My fuel pump leaks water because the fuel pump gasket is bad. The gasket itself is quite reasonable but the labor bill can be stupendous, depending on the make and model of vehicle. Especially newer models with sideways mounting, usually frontwheel drive are the most expensive as many parts have to be removed to get to the water pump. If the vehicle is not too old one can use black pepper to slow down or stop the leak and there are leak stoppers sold at your local fast parts store. Some times they work, sometimes they don't. First, we'll assume you mean an automotive fuel pump. Also, this question is not particularly applicable to modern electric pumps that are mounted inside the gas tank. We will assume that the question was asked about an old-fashioned, engine-mounted, mechanical pump.
Generally, these would never leak water. It is very likely that the fluid is coming from somewhere else, flowing down, and only appearing to be coming from the pump.
If the pump had a true leak, it would most likely spray out under pressure when the engine was cranking. A leak like this would be gasoline unless the car had somehow accumulated a lot of water in the gas tank.
A leak around the seal where the pump mounts would normally be oil. Cooling water channels are usually not too close to the pump mount.
So, more investigation is in order:
# First, identify the fluid. Is it really water, or oil, or gasoline, or a mixture?
# Is there water or gasoline in the engine's oil?
# Is the leak just a few drops? It could just be harmless condensate.
# Or does the leak stream or spray? Especially when the engine is cranking or running. Warning: If the fluid is gasoline, do not run the engine until the problem is fixed!
