Agreed, I think they should be changed whenever the coolant is replaced. I was on the fence about doing it due to access but it was quite easy. In my case i think the pieces of the tstat floating around would eventually reduce flow and my temps would climb.Hey Dean,
I had quite an opposite experience. My STBD side was running cooler and when I had the thermostats replaced, the STBD side one was in pieces, indicating that it was "always open". Hens, running cooler then the PORT side.
This was my lesson learned when taking mechanic's recommendation not to bother changing thermostats unless something is wrong. I've learned that this is totally wrong recommendation.
