<div>Mark,</div>
<div>IT is worth adding. Cost and trouble are minimal. You can buy a kit at the auto parts store (plastic tank, dual seal cap, tygon hose) for cheap.</div>
<div>Hard to say exactly how much cooling capacity it really adds.. it DOES keep the radiator full to the top, the extra quart doesn't matter.</div>
<div>I put the tank in the wheel well behind the headlight, out of sight, out of the way.</div>
<div>A very important reason to add is that it stops the leak of antifreeze, which is toxic to small animals. When we were in Big Sky for SUNI, we stopped</div>
<div>into a small museum. I will never forget the huge stuffed Condor on display. The placard said he died from driniking anitfreeze from an</div>
<div>overheated car... so sad, he was beautiful rare bird. Please install the system..</div>
