Re: Thermostat
You need to 'really' be careful with the top rad hose. If you just
remove the thermostat housing and bend the hose to get it out of the way
while cleaning the old gasket or installing, the plastic top of the rad
can/will start to leak. If it does this you need a new rad.
Other than that, it is pretty straight forward.

Re: Thermostat
Just checking, low coolant can cause the same problem. I still always check
the thermostat in a pot of boiling water. You're lucky it froze open, most
usually freeze closed. I think they sell an "upgraded" version that
garuntees to freeze open.

If I remember correctly you should make sure you have a replacement
thermostat with a "burp" hole and that the hole is on top.

Re: Thermostat
They do sell the 'fail safe' thermostats. I have one in and they/it
works for sure because I ran her hot and have full flow on a cold start
now.
