How does an radiator cool fluids?
First of all I think you are confused. The engine oil is not cooled directly by a cooler. The engine its self is cooled by a cooling system. Which uses coolant and a radiator. Answer Coolant travels through the radiator and is cooled by a combination of factors. There are air dams or cowls that gather moving air and direct it through the fins on the radiator. ther is a fan that is temperature sensitive that comes on and blows air across the fins. Most always, there are transmission coolers built into the radiator, but kept separate from the coolant to prevent the fluid from getting too hot and damaging the transmission. On some radiators there are oil coolers built into the radiator to help cool the oil much like the transmission coolers serve.

Thanks for the feedback!
on a 1999 jeep grand cherokee where is the coolant fan relay
you can take a dual fan system off a 90 91 92 93 Chevy cavalier and use it as your dual fan system just be sure to hook up both of the fan`s = = = = = = = = = = You can al…so buy a 12V electric cooling fan on Eb*y - check for corect (shallow) depth, and not too large to fit radiator. They're new so won't fail for a long long time, and pretty cheap ($25-$30 @ delivered). Hang plastic fans to radiator with nylon quick-connectors / tye-strap connects found at PepBys or HDepot, or Hardware Store - maybe 25 cents each. 4 per fan. Get long ones, pull them closed THRU radiator, cut off excess. Plenty heat resistant enough for temperatures near radiator. Best to install fans with separate relays for power direct from battery, so not to overload old switches/relays on the car; with extra relays, only milliamp draw on old switch/relay. 12v Relays 30 amp from Radio Sh*ck work well, are generic and (6-2007) cost only $6.50 @ (Model: 275-226 ) I Set up one car with 2 fans side-by-side this way: . Fan "A" Temp sensor would cut in fan "A" to cool car off. . Fan "B" was connected to A/C relay, if A/C was on, Fan was ALWAYS on, helped the A/C to work best, made sure car would not overheat. Hope this helps.
If a 92 Saturn SL2 is leaking transmission fluid and antifreeze from the transmission cooling line can you replace the lines or tighten nuts or do you have to replace the radiator?
I had a similar problem and ended up replacing both the lines and the radiator.
Answer . No coolant circulation could be:\nStuck thermostat\nDefective water pump
How do you identify the cooling line that returns fluid back to transmission after cooling it is it the lower line located on the radiator?
touch it ,the cooler one is usually return
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.
Check the fuses, check the relays and check the temp switch.
!f it is engine drivin the engine does. If it electrical it turns on at a programmed tempeture.
Too much water/contains rust. need a flush & fill.
Turn your car off. I have seen people use water to cool it down as well.
Some have an internal transmission cooler & extra small internal radiator for that purpose.
You will notice two lines going to your radiator from the transmission. One is a service line and one is a return line. The radiator has a transmission cooler built into it. I…f you have trans fluid in the radiator chances are the trans cooler is leaking. A little trans fluid in the radiator will not affect engine cooling BUT as soon as the pressure drops in that transmission you may very well have radiator coolant sucked into the tranmission and that will ruin a transmission in a hurry. You need to get this checked out as soon as possible.
Themo switch located on the radiator Or intake manifold , that is usually runs a relay fOr the. Oolong fan
Properties of the material such as thermal conductivity, specific heat, and emissivity, and the temperature of the surroundings.
Radiator have metal fins which increases total surface area of the metal body which cooling effect and hence increase the efficiency to maximum cooling effect.
