if you are asking about the cooling lines for the transmission that connect to the radiator, its easy. first disconnect the lines from the radiator (2 lines, usually on the bottom opposite the radiator outlet) then disconnect the lines from the transmission. remove the brackets holding them on, then remove.
theres a piece of plasitic, i would say midway down the line, pinch the two tabs together and simply slide it off.
On the bottom of the Radiator.
Look at the bottom or rear of radiator Look at the bottom or rear of radiator
Look on bottom or rear of radiator
Should be a plug either at the bottom or rear of radiator
Look at the bottom or rear or radiator or disconnect the lower radiator hose
if there is no drain plug on radiator, just disconnect bottom rdiator hose at radiator
Should be on the bottom or rear of radiator or remove lower radiator hose
The drain plug is on the bottom of the tank, drivers side but hard to see. But, if you cant find it, just disconnect the lower radiator hose and let it drain from there, that would do it, and its faster.
From the transmission? No? But antifreeze & transmission fluid can mix. Your transmission uses a small portion of the radiator as a transmission cooler, normally at the very bottom or side. In very rare instances, this cooler can develop a leak and allow transmission fluid and antifreeze to mix together. The only fix is to replace the radiator.
Even easier way is to remove the cap on top and loosen the drain plug on the bottom. --- easiest way to drain radiator, is to disconnect the bottom radiator hose from the radiator
