Thermostat OEM Volkswagen or OEM Nissan

I've got a 13 sport with 135k miles on it. Only ever done oil changes, spark plugs, 12v battery and a thermostat. Other than that it’s been stupid reliable.

After reinstalling an OEM thermostat, I am very happy to say my high temp issues have been solved!

We had to replace thermostat from Nissan group Infinity. So far no problem right now

Just make sure you buy a genuine Nissan thermostat. I don't know what it is about these cars, but they do NOT like aftermarket thermostats. Just spend the extra ten bucks on a Nissan part.

Noticed coolant was low and could smell it sometimes. Dealership pressure tested system and found coolant leak at thermostat housing. Thermostat replaced under warranty. Its probably been leaking slowly for a year or more.

Independent mechanic noticed leak. Dealership confirmed the thermostat was cracked and leaking. Took a week for parts to arrive. Took a day to repair. All covered under warranty.

Bypass thermostat yellow arrow Included with radiator upper hose and you should be able to find the bypass by itself.

I could only find the thermostat from VW for roughly $45.

I'll throw a lower temp thermostat see if I can get her temp to stay low as possible for now

I had my water pump and thermostat changed in August under warranty. I went for an oil change in Dec and they told me they think the thermostat is leaking. I told them they just replaced it 4 months ago. They went back and cleaned up the area around the thermostat and oil pan and said we need to monitor it to see if it's really leaking again. They were not surprised when I asked if it was possible it could be leaking again. They told me they see the part fail all the time.
