Which line is the return line on a C4 transmission?
Expert Reply: The rear line is the return line on a C4 transmission like what you have in your 1983 Ford Mustang. This would the line that you would install the transmission cooler on.
Do you have to bleed transmission cooler lines?
Expert Reply: 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.
Can I use fuel line for coolant?
Fuel line is a petroleum-resistant nitrile tube with a covering that resists weathering, ozone and heat and can be used for ethanol-laced fuels and diesel fuel. It should, however, not be used on coolant systems, oil systems or fuel-injection systems that produce pressures higher than 50 psi.
Which transmission line is the return on the radiator?
The lower line near the bottom will be the return line.
Can air get in transmission lines?
Bubbles on the transmission dipstick indicate issues in the transmission. It may result in catastrophic damages if not handled on time. The common causes of these bubbles are low or overfilled transmission fluid and air in the system.
How much psi should be in a transmission cooler line?
The cooler pressure is not published anywhere that I can find but most automatic transmission’s have about 4 to 10 PSI. You have to keep in mind the cooler pressure is low because the oil is flowing to lubricate the gears and there is not much resistance in the lines.
Can I use vacuum hose for coolant?
Vacuum hose is capable of handling 25psi, and is designed for vacuum, windshield washers, and radiator overflow use.
What kind of hose can I use for coolant?
Coolant Hose Coolant hoses come in two flavors – heater hose and radiator hose. They hoses are made the same, but the sizes are real difference. Heater hose is generally ½, 5/8, and ¾-inch in diameter. There are different types of heater hose, from standard to heavy duty.
Is vinyl tubing OK for diesel fuel?
Use only fuel rated hose for everything between the tank and the IP. Tygon hose is fine for return lines, and you could even get away with vinyl hose for the returns just temporarily for testing purposes.
Why are transmission lines not insulated?
Because they carry large quantities of electricity at a very high voltage, transmission lines are not covered by an insulating sheath. The air around them provides insulation. Therefore, it’s important that nothing come close enough to the lines to cause an electric arc.
Can overfilled transmission cause overheating?
Yes, too much transmission fluid can put your car in limp mode. This is because the excess fluid can cause the transmission to overheat and fail. If this happens, the car will be unable to shift gears properly, which will limit its speed and performance.
What does increasing transmission line pressure do?
Line pressure is just one of the components that contribute to the torque capacity of the transmission. First, it’s not the speed of the application of a clutch but the holding strength once the clutch is applied that contributes to strength. In this respect higher line pressure will give higher torque capacity.
Is transmission fluid under pressure?
ATF is pressurized by the transmission oil pump that is driven by the engine. The pressurized fluid flows through the transmission to engage and disengage the clutches and bands. A valve body, usually located in the bottom of the transmission, controls the fluid flow to the clutches and bands.
