Hi folks, I have a few questions.
As per suggested from another thread, I'm changing out the upper pipes from my radiator to flexible hoses. I drained the entire system because I wanted to replace the heater hoses aswell. When I pulled the pipes and small portion of hoses off the thermostat housing I was surprised to see they were both open, I was thinking they would be closed, but both sides were definitely open. Is that how they are supposed to be? I was under the impression they remained closed until heated to temperature then would open. Or is it possible these have slipped down keeping them open?
Also, if need be, I'm going to replace the thermostats, I have both 160 and 180 stats, what is recommended and any particular reason why one over the other? I have new gaskets, should any type of sealant be used along with the gaskets? I have number 2 non hardening g permatex.
Please pardon my ignorance, haven't been much of a auto mechanic in the past. Any help appreciated, thanks
Michael
