SOURCE: location of the Heat resistor in a 2003 Chevy Malibu?

Under the glove box, behind the blower motor itself. Remove the shroud below glove box, 2 screws and a snap-pop fitting. Be careful of the courtesy light. Remove the blower moter and disconnect the purple/black power connector to it - - you'll need this extra room to work with. 2 more screws, same size, 6.5mm on mine, 7or 8mm on some others, that holds the blower motor resistor in place. This replacement part is less than 40 bones at most parts store. Unplug, replace, re-install, test and you're on your way with about 2 hours of slow paced effort in your own driveway. Typical cost at a garage - up to $400, what a sham.

SOURCE: how do i refill the coolant in the car after replacing upper hose

hello, your car has a reservoir tank were you put the coolant in at all you have to do is start your car and it'll draw coolant from there after your car runs a few minutes check your coolant reservoir tank it;ll probably be close to empty also since you took your hose off you'll have air in your system that you'll need to bleed out of the system otherwise your car will over heat and you wont get proper coolant flow the bleeder valve is a small brass bolt that you can use a wrench to open and close it with, with your car running just open the valve until you see coolant flow out then close it do this till you get a solid stream of coolant flow and check your reservoir often while doing this keep it full.

SOURCE: temp guage showing hot, not getting any heat for 1992 Mercury Cap

If the hoses to and from the heater core are hot , and you say the heater core is hot , then the only answer is that the air duct that flows into or out of the heater core plenum ( housing ) is not opening.
Heater control on dash borad inoperative.
Not sure about 92 capri , some cars have a cable linkage , some work on vacume motors.
Try to find a haynes manual for your car , they will walk you through almost every step of anything you may ever want to do to your car.

You seem to know what you are doing , but I gotta ask ........the heater core you felt was up behind the dash inside the passenger compartment of the car right ?

Where is the waterpump to add coolant and water in santafe 2005?

The water pump is enclosed on the front of the engine. The bottom radiator hose connects to the water pump inlet.
You do not add coolant to the water pump. You add a 50-50 mix of antifreeze and water into the radiator cap opening. Or you can buy the coolant already mixed with water and just pour it into the radiator.

The coolant system uses the water pump to circulate the coolant through the engine and then into the radiator via the upper radiator hose for cooling it off, and it then goes back into the engine through the bottom radiator hose. When the engine is warmed up, the coolant constantly circulates through the engine to radiator and back into the engine.

What is mean by thermostate valve

The thermostat is a critical part of your coolant system, the system that circulates water and antifreeze (coolant) through the engine to keep it from over-heating. It is called a valve because it can open and close, depending on how hot the coolant is acting upon it.
The reason to put a thermostat in the coolant system is to allow the engine to reach normal operating temperature quicker (and therefore operate at peak efficiency) than without a thermostat.
When the engine is cold, the coolant is at normal outside temperature, so the thermostat is closed. This means when you start the car, the coolant starts circulating through the engine, but can't flow into the radiator. With a closed thermostat, the coolant just keeps circulating around in the engine until the car warms up, the coolant gets hot, and the heat acts upon the thermostat, causing it to open at a certain temperature (about 185-195 degrees F.), With the thermostat now open, the coolant can now enter the upper radiatior hose and flow down the radiator to cool itself down, before going back into the engine through the lower radiator hose.
So the thermostat is always found on a car in the area where the upper radiator hose connects to the engine. Thermostat closed-water can't circulate through the radiator. Thermostat open- coolant is forced through the hose into the radiator.
I hope this helps you understand the thermostat valve and why all manufacturers include them.

My malibu 03 heats up could the radiator be clogged? i changed the spark plugs plus the water pump, the upper hose and the bottom hose, and the thermostat i dont think there are leaks in the coolant tank,...

You may have air trapped in the system. Air can get sucked into the system if you have a loose hose or a bad seal on the radiator cap or the over fill tanks cap. Try to see if your vehicle has any bleeder valves. Should be at the highest point in the cooling system where the air gets trapped.

What is the black hose on top of engine. Under the header covers?

Upper Radiator Hose and Thermostat
  • A large part of a radiator's function is made possible by the upper and lower radiator hoses. The upper radiator hose controls the flow of engine coolant from the radiator into the car engine. In a cold engine, engine coolant is stored inside the radiator. The engine coolant is held inside the radiator until the engine becomes hot enough to warrant engine coolant circulation. When an engine reaches operating temperature, the thermostat valve, which is located at the far end of the upper radiator hose, opens up and allows engine coolant to flow from the radiator into the engine.
