Heating AC and Engine Cooling

The basic rule of thermodynamics is that heat goes from where it's hot to where it's not. The coolant in a vehicle takes (draws or sinks) heat from the engine, and this heats the coolant. The hot coolant carries off the heat, and then flows through the radiator. Air passing the elements of the radiator, because it is cooler, takes (again, draws or sinks) heat from the radiator's fins, which transfer the heat of the coolant out. The hot coolant loses heat energy as it flows through the radiator, and heat from that coolant is passing through the metal radiator elements into the air flowing past. The radiator sets up a relatively large surface area to that passing air so that "a lot" of heat transfer can take place. There is what is called a thermal gradient across the elements in the radiator. Hot coolant inside and relatively cool air outside those elements set the ends of the gradient. Heat goes from where it is hot, the coolant, to where is it not, the air. If you guessed that there must also be a thermal gradient across the metal of the engine between the combustion chambers and the coolant chanels in the block and head, you'd be right. That thermal gradient drives heat out of the cylinder walls and head into the coolant in the coolant channels. It's just that simple. Remember that any time a temperature differetial exists, a thermal gradient exists. A thermal gradient is the "force" of heat transfer in the science of thermodynamics. Easy as pie.

Either the thermostat is stuck shut of the water pump is bad. Make sure that the coolant is full as well, then check the thermostat and pump to see why the coolant isn't flowing.

your heater most likely does shut off. this is called the burner orheat exchanger. the fan will continue to run until the exchanger cools down. check you thermostat setting to see if itis on-auto ,-or continous.

Loose belt -- replace or lubricate

ADD-ON If it is a metallic squeal that continues for a minute or so after the car starts it could be your water pump bearing. Get your mechanic to check it out and replace before you need a tow truck.

Surfactants include liquid soap, ink, shampoo, and conditioner. Other types are insecticides, hand sanitizers, and components of paint and toothpaste.

No, all engines cool by radiation.

The Latissimus Dorsi is located around the sides of your back.It is a muscle in your body.

the main cool colors are blue, purple, green, and other colors that might remind you of the ocean or a cool night are the main cool colors as i learned in school!!

Codey McCloud invented coolness and he is so cool. If you hate codey mccloud you suck balls.

Hi Chase and brisk is so cool because of its cool taste

A lot of people assume that the problem is the heater core. The heater core is difficult to change on the Ford trucks. They have it buried in the plenum box and you have to remove the steering wheel, steering column, dash, evacuate the refrigerant system, drain the radiator, and remove the plenum box to get to the core. Replacing the core is easy, getting to it is a day's work. The Expedition is particularly difficult to get to. It is almost above the transmission tunnel and well buried behind the dash. The Expedition uses the same plenum box as the F150, so any information on that system applies to the Expedition/Navigator.

You need to be sure that the heater core is really the problem before tackling this job. If you have a pool of coolant on the floor, you'll have to go after the core. If the problem is lack of heat, there are some things you need to eliminate before tearing into the truck. You need to make sure that coolant is flowing through the core. Check the temperature of the heater hoses going into the firewall when the engine is cool and see if they warm up together as the engine warms up. If both hoses get hot at about the same rate, this is a good indication that coolant is flowing through the core. You can also remove the hoses and flush the core with a water hose splice from Home Depot and a water hose. Water should flow unobstructed through the core.

If it appears that coolant is flowing and you don't have obvious leaks, the next step is to check the blend door. This door controls the air flow through the heater core and failure is common on Ford trucks. When the door breaks, it can block the flow of air through the core and kill heat and will also have an impact on AC. If the system seems to work intermittently, it's a good indication that the door is broken and rattling around randomly blocking or opening the passage to the core.

For diagnostic information on how to check the operation of the blend door and a cheap easy fix, check the heatertreater listing on Ebay or the web site at heatertreater.net. The dealer fix for the blend door is basically the same procedure for replacing the heater core, so it will be expensive. The HeaterTreater alternative will solve the problem at a fraction of the cost and work and is well within the capability of the average shade tree mechanic.

no check your owners manuel for the proper coolant if you don't have one u can call the dealership and they can tell u

Driving a car with an overheated engine, will cause a build up of pressure that can blow gaskets and cause other internal damage. It's an expensive repair, or may require replacing the engine. Some engines can handle heat better, frequent motor oil changes are recommended for better performance...

yes it can and if you have aluminim heads with a cast iron block you need to put new bolts in as well

about 1 gallon your owners manuel should have this info

A 1300 cc complete engine with tin and generator, clutch, intake and carburerator and stale air heating exhaut manifold, bolted to a 2'x3' pallet weighs 210 pounds. The pallet weighs 18 pounds so a good estimate for shipping without a pallet is 200 pounds.

The car normally pushes it out the over flow.

Not very far until you have major problems.

Yes.
