Hey thanks, I didn't know that the thermostat has a bypass hole. I have not done the job yet but looked at a few thermostats online for this particular car and didn't see any bypass holes. I have heard of some thermostat having a hole and some don't. keeping the block drain cock open until i get coolant come out is agood Idea, i'll try that.

one more question ctscott since you seem to have lots of experience with these yaris cars, Is it a common failure for the Radiator to develop cracks on the upper section? on these cars I mean? Poor quality part from toyota or previous owner just put a used cheap radiator? The car is only 4 years old and I would think a radiator would last longer than that....hhmm?
