Re: 4kq: no heat

Thermostats are cheap. Just get a new one. Definitely sounds like your
thermostat is stuck. Follow the bottom radiator hose to where it attaches to
the block (water pump). There is a little fitting there with two (10mm head)
bolts holding it on. Underneath there should be the thermostat. I actually
don't know this from experience, as I've never changed one, that's just where
it LOOKS like it is. I suppose I could be completely wrong, and then I would
feel like a dumbass, but since that's where the water pump is, I figure that's
where the thermostat is.
