'92 Acura legend
When it started getting cold enough
outside I would turn my heat on and it
would work for a few minutes then my
car would say it was overheating then
blow out cold air, then I would turn my
heat off and the heat gauge would go
back to normal. I rarely have heat only
if I am lucky. I just got my thermostat
changed and at first it was blowing
cold air, I revved it up and when I
stopped doing that then the heat
worked great so I was happy it was
working but then my heat gauge was
"overheating" slowly and the heat
slowly got cold. Is my car just junk?
