Cooling lines from transmission to radiator?
Transmission fluid cooler hoses.
Nothing on a manual
If you are speaking about the two small hoses, yes. That would be transmission fluid.
With a release tool.
It runs through the radiator to cool. It comes in through one of the hoses attached near the bottom of the radiator
Yes! both the radiator and the hoses are swapable :) Just besure that if your vehicle has a automatic transmission the radiator has the automatic transmission cooling line fittings.
Your transmission pan isn't large enough to cool the transmission fluid like the oil pan, so there is a transmission cooler that looks like a miniture radiator that is typically located in front of the radiator.
The transmission cooler lines are located coming from the radiator on the bottom. One is for the sending and the other for return. The lines are high pressure, just as your radiator hoses are when the car is running. The lines go from the radiator to the top of the transmission.
check your radiator hoses and change gaskets
the thicker hoses are oil cooler hoses the thin ones are cooling line for auto transmission
If you have a 4.3 vortec,Locate and open radiator drain plug into container. (apx 3 gallons) Remember antifreeze is posion!!! Remove radiator cap. Loosen intake hose clamp, Loosen the two wing nuts on the plastic part of the air intake atached to the top of the radiator and remove. Loosen the radiator clamps and remove the hoses from the radiator. Loosen the two transmission lines.(DO NOT BEND if possible) Remove the two bolted clamps on the top. Carefully lift straight up and out.When replacing, be carefull not to cross-thread the transmission lines.
If you are replacing radiator hoses, make sure to drain coolant first There are 2 hoses upper and lower hose looking down in front of the engine: you have to remove the air duck funnel that is attached to the radiator, upper hose should become more visible lower hose is located on the left side of the radiator fan
