Faulty OEM Thermostat
Posted 19 August 2011 - 12:33 AM
The engine showed no other sighs of head gasket failure, except the temp gauge climbing at freeway speeds. I was very hesitant to do a HG job, as it just didn't seem like that was the case. Anyway, I stopped by Shucks today, picked up a cheapo thermostat, installed it, and the overheating is completely gone.
So, I'm on my way to Subaru tomorrow to pickup another factory thermostat. Just wanted to share, even New, factory thermostat's can fail.

are you sure it wasn't:
an air bubble?
or a partially clogged radiator that got semi-flushed out by the *fluid change* that happens when you replace a thermostat?
you could probably test it in some boiling water, see how far it opens.

It is also possible, being that these are just stamped sheet metal parts - that it could have been tweaked in shipping or dropped causing it to bind durring it's opening/closing process and thus stick at less than fully open....
BTW - if anyone can find an online supplier of the TAMA branded units I would love to hear about it. I use a lot of these and would love to buy them in large quantities to possibly save some money on them..... alas I haven't found any suppliers other than my local guys and they are basically within $1 of the dealer wholesale price....
