Thermostat OEM Audi or Wahler
I have had a car not bleed properly/ run hot (but not overheat) only when using the wrong thermostat. Replacing it with Wahler fixed the issue.
Pros: fixed bleeding issue
Vehicle:
Porsche
A proper Wahler thermostat is what solved it.
Pros: solved issue
Vehicle:
Porsche
I just put a new Waller in every 8 to 10 years when it comes time to redo the cooling system. Never had a leaking or stuck thermostat but we do live in Southern California, so I think things tend to last longer Here
Pros: no leaking, no sticking, long lasting
I've had a Wahler fitted for 1.5yrs and everything's ok so far
Pros: everything ok
Spend slightly extra and get a quality OEM Wahler thermostat.
Pros: high quality OEM
My Q5 with 75,000 miles on it developed a leak in the water pump area. Initially Audi denied there was a leak, so I took pictures and showed it to them. Then they diagnosed it with thermostat leak.
Pros: warranty on that part
Cons: leak in water pump
Vehicle:
Audi Q5
Mileage: 75000 km
I’ve replaced it twice and it starts leaking from there in about 2000 miles or so. I’m willing to bet that thermostat is a Wahler brand. They are known to leak like this.
Cons: leaks after 2000 miles
Vehicle:
BMW
Mileage: 3218 km
The wahler thermostat is either broken or its too cold where i live cause the car never really gets up to temp (or my temp sensor is broken).
Cons: never gets up to temp
Vehicle:
BMW
The Wahler one's are rubbish. Did the same after my fucking brand new Wahner DID NOT work....
Cons: rubbish quality, did not work
Vehicle:
BMW
I've replaced my thermostat with a new wahler one and I have the same problem which is that it openes at around 70°C and cools my engine to almost 50°C, from what I understand the thermostat is mechanical and electronically assisted to open faster/wider
Cons: opens too early, cools too much
Vehicle:
BMW
