Thermostat Wahler or Duralast

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.

A proper Wahler thermostat is what solved it.

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

I've had a Wahler fitted for 1.5yrs and everything's ok so far

I've used Autozone's Duralast thermostats without issue on my old Integra.

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.

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).

I warranty my shitty duralast thermostat (I hate duralast but when I gotta get to work the next day it works in a pinch it works) now after a 5 am swap I’m good to go

I’ve changed mine once already recently (it was a duralast thermostat because I’m stupid, that might be the current issue) and it’s still acting similar and trending towards overheating at 60+ mph even with the radiator fans on high. The radiator in lines are frigid after it’s been running at mid/high temps and the radiator out lines are hot

The Wahler one's are rubbish. Did the same after my fucking brand new Wahner DID NOT work....
