The bypass I mentioned is on top of the thermostat housing on the 2.1l
engines. On the 1.l engines, it is located on that coolant manifold in
the engine compartment with the 4 large hoses attached to it. It has a
small hose that leads to the pipe on top of the engine. This allows the
air to escape and return to the reservoir.

Subject: -Thermostat bypass, was Bleeding front radiator

---OK,
Thanks for all the responses to this, but everyone is pointing me to the
radiator bleeder on the top passenger side of the front radiator.

So the question remains:  is there a thermostat bypass valve (a way to
open
the thermostat manually, with the engine cold)??

I know about the radiator bleeder already mentioned, and the bleeder on
TOP
of the thermostat, which seems to function the same as the front
bleeder,
i.e. open a little, watch until clear stream of coolant comes out.

Dennis, you out there?  Help us out here...
