Quick Answer: How To Plug Transmission Cooler Lines On Radiator

Can I delete transmission cooler lines?

Remove the two transmission cooler lines from the bottom of the radiator. These two lines can be accessed either from underneath the hood or underneath the vehicle. Use the flare nut wrench to remove the lines in the same manner used to remove the lines from the transmission.

How do transmission cooler lines connect to radiator?

Transmission coolers do not attach to the radiator. They attach in-line with the transmission fluid return line. It is common for an OEM transmission cooler to be built into the radiator tank to be cooled by the coolant in the radiator.

What two lines connect transmission to the radiator?

The hoses traveling from the transmission to the radiator are called transmission cooler lines. They channel hot transmission fluid to the radiator, where it is cooled, then return it back to the transmission. They typically resemble brake lines and are made of metal.

Can I use rubber hose for transmission cooling lines?

You can use rubber hose, but make sure it’s transmission cooler line rated. The pressure is quite low (12-15 psi). Double clamp it or use FI type clamps instead of the worm-drive style.

Does transmission line go to radiator?

How Car Transmission Lines Work. Car transmission lines connect your vehicle’s transmission to the vehicle’s radiator. Also known as transmission cooling lines, they are typically made of metal or composite aluminium and rubber hoses because they can handle the flow of hot transmission fluid.

Does transmission fluid run through the radiator?

All transmissions have a cooling line that runs to the radiator. A separate fluid passage circulates the transmission fluid through a portion of the radiator to cool the fluid.

Which transmission line goes to the top of the radiator?

Generally the higher line on the radiator has fluid going INTO the transmission and the lower one goes back to the transmission, so the higher line has fluid coming out of it and the lower line sucks it back into the transmission.

What happens if you put transmission cooler lines backwards?

If you had it reversed, the pump would be trying topush fluid through the bottom of the cooler, up through the cooler, out the top into the bottom of the rad, and up through the rad to the top. More weight to push.

Which transmission line on a radiator is the return line?

The lower line near the bottom will be the return line.

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.

Are transmission cooler lines high pressure?

Its NOT only pressure you have to worry about, its also compatibility with the trans fluid. NOT aware of the pressures being any higher than other transmissions, so if you use “Transmission Cooler Hose” you should be fine.

Is fuel hose OK for transmission fluid?

Fuel line will work for oil or atf. They also say if it is high pressure on the hose”fuel injection”. Just dont use vacuum hose. You will be fine with high pressure fuel line, but do not use the low pressure stuff.

Can you use transmission oil cooler hose for fuel line?

Fuel Line Hoses. Fuel lines are only the tip of the proverbial iceberg. So you can probably use power steering hose in a transmission oil cooler application, but not vice versa, at least not in a pressure line application.

How do you change a transmission cooler line?

How to Change Transmission Lines: Do It Like a Pro Raise the Vehicle. Drain the Transmission Fluid. Remove the Transmission Cooler Lines. Drain More Fluid. Spray Brake Cleaner. Install the New Transmission Lines. Replace the Transmission Fluid. Lower and Start your Vehicle.

Do you have to bleed transmission lines?

Do i need to bleed the cooler once installed or will the air just get flushed out? You would not need to bleed the transmission cooler part # D13503 before you install it on your truck. The fluid is thick enough and the pressure it high enough that air bubbles would immediately work themselves out.

Does transmission cooler use antifreeze?

The cooler for the automatic transmissions are placed inside the radiator, the reason behind this is the antifreeze provides the perfect environment. It warms the transmission up with it’s cold and keeps it from getting too hot in extreme heat.

Can I bypass the radiator transmission cooler?

Bypassing your radiator transmission cooler would likely cause the fluid in your transmission to over heat causing premature transmission failure.

How do you know if your transmission fluid is leaking into radiator?

Look at the color of the transmission fluid. Fresh transmission fluid is a bright red color due to dye that is added to the fluid. If the fluid is a milky pink color, it has either antifreeze or water in it.

How much does it cost to replace transmission lines?

Like all parts of an engine, transmission cooling lines can wear out. If they break or develop a leak, you will lose transmission fluid, leaving your car vulnerable. Thankfully this is a fairly simple fix, and most transmission line repairs cost between $100 and $500 dollars.

What size are 4L60E transmission lines?

-6 x 1/4NPS is the correct size for GM turbo 350, Turbo 400, 700R4, 4L60E and many other GM transmissions. These have a straight thread and seal on the gasket.
