Do you need to plug transmission cooler lines?
You don’t need to plug them at all. The lines are not open to the lower tank. The pipes are either end of a transmission cooling loop inside the lower radiator tank.
Are radiators transmission specific?
see more. When purchasing a radiator, the transmission only matters if you have an automatic transmission. If you have an automatic transmission then you’ll either need a Radiator with a Internal Transmission Oil Cooler (TOC), such as this one, or you’ll need to get an External TOC.
How do you replace transmission cooler lines in a car?
Attach the new cooler lines to the radiator and the transmission as well as any hangers that they may have been suspended from. Fill the transmission with the manufacturer’s recommended fluid to the proper level indicated in Owner’s Manual. Start the vehicle and check the transmission dipstick to make sure the fluid is at the proper level.
What to do if your transmission cooler is leaking?
If you simply notice that a line is leaking, that can be a simple fix depending on the location of the leak and line itself. Depending on the transmission cooling system routing, it is not too uncommon to have the transmission cooler lines leaking at the radiator if the lines are starting to rust.
What are the symptoms of a transmission cooler failure?
1. Transmission Line Leak One of the most obvious transmission cooler failure or blown transmission line symptoms is a leak. When a line leaks, there will be transmission fluid on the ground near where the leak is coming from.
How do you remove transmission line from Radiator?
Locate the transmission cooler line fitting at the back of the radiator and remove it by turning it counterclockwise. Have a rag ready as transmission fluid will seep out. Follow the line back to its insertion point in the transmission. With the appropriate sized wrench, unscrew the fitting from the transmission by turning it counterclockwise.
How do I remove transmission lines from Radiator?
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.
Which line is the return to transmission?
The white arrow on the driver side is the return line from the radiator to the transmission. You want the tap into the return (driver side) side. This will allow the ATF to be cooled even more after going through the radiator and then through the additional new cooler and back to the transmission.
What causes a transmission cooler to leak?
Heat causes oxidation. Oxidation causes a brown tarnish that coats the dipstick, transmission case and other components inside the transmission. This tarnish also causes transmission valves to stick, resulting in delayed and unusual shifting. If the fluid is pink and milky, the transmission cooler is leaking.
What is a transmission cooling line?
What is a transmission cooling line? Your transmission cooling lines, often just called the transmission lines, are the lines that connect your transmission to the radiator in your car. The hot fluid cools off in the radiator and then heads back to the transmission.
