25-Piece Master Quick Disconnect Tool Set for Fuel, AC, and Transmission Cooler Lines

The spring-lock and quick-connect couplings on cooler lines, fuel lines, and AC lines are built to lock and stay locked, and they will fight you every time unless you have the right tool to spread the retaining clip. Trying to pop one loose with a screwdriver usually ends in a cracked fitting, a bent line, or a gash in your hand. This 25-piece set gives you the correct tool for each size so the coupling releases the way it was designed to.

It covers the sizes that actually matter on a transmission job: the 3/8 and 1/2 inch oil cooler lines on GM pickups and Fords with automatics, plus the 1/4, 5/16, 5/8, 3/4, and 7/8 inch fuel and AC lines you run into on the same vehicle. You get seven aluminum clip removers, four spring-lock disconnect tools, seven plastic clip tools, a scissor-style disconnect, and dedicated tools for the GM pickup cooler lines and the odd 4.0L V6 Ford tubing. Everything is color coded by size so you grab the right one the first time.

Built from anodized aluminum, steel, and reinforced plastic, and it all drops into a blow-molded case so nothing walks off between jobs. If you drop or flush transmissions you reach for these constantly, and buying the set once beats buying single-size tools every time a new fitting shows up.
