Very interesting, appreciate the details. Simply it's a very poor design with plastic parts exposed to heat that keep the spring under tension. Normally it should have been the actuator that would fail as mentioned above, but since the housing is this fragile, you guys have a much worse problem on hand.
I assume these tabs gave up at close to 10 years age? If so, this part becomes a must be replaced item
at no more than 7-8 years old.
Is the thermostat easy to access?
If you click on the link in my previous post (Land Rover Forum) you will see the procedure.
It is very difficult to remove all of the electrical connections for the intake manifold.
It might be possible to do the work without removing the manifold but I can't get my hands in there.
As for the design of the Thermostat; I do wish that Volvo had made the plastic tabs larger so that it wouldn't fail at ~10 years.
Having said that I do appreciate the Engineering that went into the design.
And yes I agree that the Thermostat should be replaced in ~10 year intervals.
If you look at my list above most of the items listed should be done by 10 years; if you want your Volvo to last 20 years.
I've owned my 2008 LR2 since new and I am at 114,000 miles and I expect to get more than 200,000 miles without a major repair.
In case its unclear I really like the Volvo Power-train in my LR2, Volvo reputation for reliability is part of the reason that I bought my LR2.
I am completely satisfied with my purchase.
