Rein ヒーターホース（4ウェイバルブからバッテリーへ）Tesla Model S（2012-2016）用

I was sick of chasing coolant leaks on my old Tesla, so this replacement hose was a relief. The OE direct replacement design meant it matched perfectly, and I didn't have to cut or adjust anything to get a leak-free seal.

The hose slipped right into place on my 2014 Model S—no cutting or wrestling like with the old one. Installation took maybe 20 minutes, and the factory-style connector gives me confidence it won't leak.

I was tired of coolant leaks after every hose swap, but this direct-fit replacement cut my installation time in half and sealed perfectly on the first try. No cutting or adjusting needed, just a simple bolt-on that’s held up for two months now.
