Rein ヒーターホース（3方弁から4方弁）Tesla Model S (2012-2021) 用

Finally fixed that annoying coolant leak I’d been chasing for months. The pre-formed shape fit perfectly into the engine bay without any cutting or adjusting, which saved me a ton of time.

The 3-way to 4-way swap took me under an hour because the hose is shaped exactly right—no cutting or fiddling like with the old one. Feels solid and sealed up tight on the first try, so I’m not worried about leaks down the road.

The direct replacement design saved me a ton of time under the hood, and the fit on my 2015 Model S was absolutely perfect. No cutting or adjusting needed, just a clean swap that stopped a persistent coolant drip.
