My car was designed to run without one. A properly setup car doesn't puke fluid out. I drive around in 100F+ heat without any problems. Fluid level in rad is at proper level.Looks near identical to one I got from NAPA the past Spring. Mine works very well. Mind you, I still check the fluid level in the radiator top tank to insure its at the level specified in the FSM:1.25" below the filler neck seat. I've found that more than this doesn't permit enough room in the tank for proper cooling, and sure enough, the temperature can go up 10 degrees or more.
With the right coolant level, I get a presence of just a few table spoons in that overflow tank when the engine is cool. But when parking briefly after running in hot traffic, it does catch a bit, which then gets sucked back into the radiator as the coolant contracts. My system maintains excellent equilibrium.
Put the tank next to the radiator, with the cap at the same height as the radiator cap, run the overflow to the bottom of the tank, and all should be well.

Part is gone. Thx
The reason they started using overflow tanks was the operating temperature of the engines was increased do to the smog requirements. Leaner mixtures, catalytic convertors, retarded timing etc. all lend to increased heat. They also started using "hotter" thermostats to get the engine temperature up for emissions reduction.yes lets use a reduced amount coolant because the factory was too cheap to use one
