OEMTOOLS 24688 Transmission Oil Cooler Line Disconnect Tool 3/8 and 1/2 Inch

Anyone who has tried to pull a transmission cooler line at the radiator knows the plastic disconnect tools that come in a bin at the parts store. They flex, they cam out, and they usually snap on the first line, leaving you fighting the spring-lock fitting with a screwdriver and a lot of swearing. This is the metal version that actually does the job. It is a forged step-scissor that seats squarely on the collar of the quick-connect, spreads the internal spring evenly, and lets the line slide free instead of binding.

The tool is cut for the two sizes you meet most on domestic transmissions, 3/8 inch and 1/2 inch, and it is sized right for Ford and Cadillac cooler line fittings at the radiator and the case. At 4.5 inches long and about an inch wide it is small enough to slip in behind the radiator support or up alongside the pan where there is no room to swing a hand, and the corrosion-resistant finish means it lives in the drawer between jobs without rusting up. If you service transmissions, flush coolers, or swap a radiator with an integrated cooler, this is a one-time buy that pays for itself the first time it saves a fitting. Ships from the USA.
