Thermostat Gates or Motorcraft

Man, you just get the thermostat itself. Nothing more. Something like that was for 2008 Rabbit (2.5 I-5). Mine car had exactly same symptoms. It would reach 70 C and maybe at some point 80, but had tendency to stay cool (below 80) when driving. I know thermostat opens at 80 C, so anything below 80 is not quite right.

I got the GATES 34710 Thermostat. I haven't had any problems since replacing it 3 years ago.

Forgot to add I test drove her last night to the store, holy $hit it runs like a beast, if I had to guess it feels like it got 20hp back and idles smooth as a new mk7 no shaking no cel lights just butter, it accelerates much smoother and faster then I ever had it. Such a difference it was amaze balls.

By the way, that Gates thermostat (good brand - OEM quality, includes gasket) is $24, delivered, while AutoZone in my area wants $32
