Thermostat OEM Volkswagen or AISIN
Reviews
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.
Pros: stupid reliable
Vehicle:
Volkswagen Touareg
Mileage: 217261 km
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.
Pros: replaced under warranty
Cons: coolant leak, slow leak
Vehicle:
Volkswagen Golf
Mileage: 27199 km
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.
Pros: covered under warranty
Cons: cracked, leaking thermostat
Vehicle:
Volkswagen Golf
Mileage: 43000 km
The OEM Aisin thermostat opens at 185, staying completely closed until 180 where it can open up partially allowing proper circulation and proper temperature control. The engineers at Nissan designed this cooling system to function in a certain way at very specific temps. ONLY USE THE AISIN 185 OEM thermostat in these trucks.
Pros: proper circulation, temperature control
Vehicle:
Nissan

Part number: 1K0121087R
I could only find the thermostat from VW for roughly $45.
Bruce and I and my Dad replaced the thermostat, timing belt, water pump, and thermostat on the P. All went well, except that VW doesn't know how to do their job very well and got the wrong pulleys. But they did get everything else correct, and for a good price too.
Pros: good price
Cons: wrong pulleys
Vehicle:
Volkswagen Phaeton
today I replaced the thermostat on my GLI too. What a pain in the ass!!! my back hurts so bad!. Anyways it took me almost 6 hours to complete the job. Now the car feels a lot more powerful, the old thermostat was opening at 80oC so it was overcooled all the time, heater just blew mild hot not hotter as it should and it was burning gas like a v8, It was doing 16-18mpg at most in city driving. I just checked with VCDS and the engine temp is at a solid 93oC constant temp, I took it for a ride for about 10 miles and it did 28mpg so I am pretty confident that the old thermostat just plain sucked. 6 hours well spent!
Pros: car feels more powerful, better mpg
Cons: pain in the ass, back hurts
Vehicle:
Volkswagen

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.
Cons: leaking again after 4 months, part fails all the time
