Top best answers to the question «What is the difference between an engine oil cooler and a transmission oil cooler»

Engine coolers need to handle up to at least 100psi(most pumps bypass about 85-90+) as they are usually plumbed in right before or after the oil filter which sees full pump pressure. Trans coolers typically are the last/near last hydraulic part in the system as they're under very little pressure.


Those who are looking for an answer to the question «What is the difference between an engine oil cooler and a transmission oil cooler?» often ask the following questions:

❓ What's the difference between transmission cooler and tube and fin?

  • The main difference is in the ability to cool the fluid. The tube-and-fin style has a tube that carries the transmission fluid through the cooler. It is also distinguished by its turbulators, which agitate the fluid to get more of it to contact the aluminum in the tube.

❓ How does a transmission cooler cool the engine?

  • The air moving over the fins of the cooler cools the fluid, which is then routed back to the transmission, engine or power steering pump in a continuous loop through the return line. 2. How do you attach the transmission cooler in front of the radiator or air conditioning condensor?

❓ What is difference between cooler and condenser?

Type your answer here... the basic difference is the phase of the material which is to be cooled i.e.in condencer it is in vapour phase & in cooler it is in liquid phase.

What is auxiliary transmission cooler?
  • An auxiliary transmission cooler is an add on automatic transmission cooler which adds extra cooling capacity to your car or truck transmission. Perhaps the best upgrade one can do for their automatic transmission.
What is auxilliary transmission cooler?

A good example is a transmission that stays within the normal range of 175 to 200 degrees Fahrenheit when not towing. An auxiliary cooler may help with temperature that rises slightly above this when towing. An auxiliary transmission cooler will NOT increase the capacity of an overloaded vehicle.

What is cvt transmission cooler?

What kind of cooler is used for CVT transmission?

  • The snow and ice accumulated on the cooler, greatly reducing air flow. Modern transmissions have a built-in bypass that will cut off the flow to the cooler under severe cold conditions. A Hayden by-pass cooler can be used in these applications. Many vehicles now feature CVT transmissions and use a liquid-to-liquid cooler for the transmission.
What is the transmission cooler?

A transmission cooler operates like a heat exchanger mounted adjacent to your car's radiator. Hot transmission fluid flows through the unit and comes in contact with a series of fins or plates. The resulting heat dissipation cools the liquid as it cycles back into the transmission.

What is transmission oil cooler?

The oil cooler is designed to lower the temperature of the transmission fluid to make it easier for the internal parts of the transmission to use. There are two types of transmission coolers, the type found inside the radiator or the kind that is external to the radiator that usually sits in front of the AC condenser.

What size transmission cooler line?
  • The size of the cooler passages in a C4 are no larger than 7/32". There is more than enough pressure to get oil through a 5/16" line to cool properly. A 3/8" line is slightly better because it has less friction but you will never notice any added cooling.
What type of transmission cooler?
  • There are four different types of transmission coolers; tube and fin coolers, plate and fin, stacked plate, and heat sink transmission coolers. Each of which has their own set of benefits compared to the others.
What is the difference between internal and external transmission oil coolers?

An internal cooler is a small internal radiator inside the lower end of a regular radiator. It has two lines running to it from the transmission. This internal radiator gets cooling from the "coolant" that flows through the radiator regularly during running of the vehicle. The reason it is at the bottom of the rad (usually a veritcal flow type) is that the hot coolant comes into the rad at the top and then is cooled as it falls to the bottom. The smaller internal rad is also cooled by this "cooler" coolant (antifreeze and water mixture) and thusly cools the hot transmission fluid. This internal rad is separate from the regular cooling system and is a "closed System" within a system. An EXTERNAL transmission cooler is a small rad that is used exclusively for cooling of the automatic transmission fluid. It is completely separate from the rad but many times is mounted in front of the radiator. External coolers have much more volumetric efficiency and can handle larger quantities of fluid. They are installed on anything that may have a trailer towing package. Automatic transmissions get very hot while towing and need the extra cooling if they are pulling a load.

What is the difference between service engine and maintenance light?

The simplest explanation for the difference between a check engine light and service light is the former indicates a major problem and the latter indicates a need for maintenance or regularly scheduled service.

What is difference between refrigerator air cooler and how?

A refrigerator has a freezer and a cooler compartment. Very cold air from the freezer compartment is blown over the cooler compartment below to cool the product while a Cooler has no freezer compartment.

What is the difference between oil cooler and radiator?

An engine oil cooler does the same job as the radiator. It also does the same job as cooling fins on air-cooled engines. It is a heat sink that transfers heat away from the engine to the atmosphere… You want to keep oil from getting too hot.

What is the difference between the check engine light and service engine soon light?

The Check Engine light comes on when the ECU detects something is wrong with the emissions system on the vehicle. You will need to have the ECU scanned with an OBD2 scan tool. The Maintenance Required light comes on to alert you to the fact that some scheduled maintenance, as outlined in your owners manual, is due. It can be as simple as an oil change or can be something else. Look in your owners manual to find out what service is needed.

What is the difference between an evaporative air cooler and portable cooler?
  • One of the major differences between an Evaporative Air Cooler and either a Portable or fitted-system is that evaporative coolers do not have exhaust hoses or outside condenser boxes. They are also different from Air Conditioners in that they do not provide “refrigerant air” but rather provide “cooled air”.
Is transmission cooler necessary?

Transmission coolers help to protect your transmission when you turn up the heat. For the same reason, the addition of an auxiliary transmission fluid cooler isn't just necessary for those who tow trailers anymore…

What causes transmission cooler lines leak?

Transmission cooling lines leaking means either low-level of fluid or interrupted flow in the transmission. In both cases, the result is an overheated transmission that may stop functioning if the condition persists. Sometimes, it is difficult to spot the leak at the initial stage.

What is a transmission cooler leak?
  • Transmission Harsh Shift. A leak in the transmission hydraulic lines that travel to the transmission cooler can empty a transmission of fluid at a slow to even dramatic rate depending on the size of the leak. Any automatic transmission that looses or has less fluid than it needs to run properly will most likely be coupled with...
