hey all i was swapping my thermostat yesterday getting prepared for the montana winters. i was running a 160 thermostat for the summer and just picked up a 190 for the winter. the thermostat swap went as well as could be, i can get the three bolts out without messing with the belt fan etc. anyway got the swap done and went to bleed the system. Then the problems started. the heater works great blowing warm air, the fill tube going to the block is nice and hot and the radiator is super warm as it should be, BUT the lower hose is still cold as can be and the engine temp is barely hitting the N of normal. the temp will go up to the n and then you can watch it dive back down to cold like the thermostat is opening super low. i went ahead and took the thermostat back out and boiled it to make sure it worked. put it back in and still having the same problem. my local mechanic told me to get it warm shut it off and pop the cap to fix this. been doing that for the last 24 hours and im seeing small amounts of bubbles but the lower hose is still cold and the temp gauge is not rising. need this for work and dont know what to do!
