Thermostat replacement

[Fless]

Confused about what? I replaced thermostat cuz i temp gauge would drop to 0 and fans would come on. Replaced ECT and problem came back. Everyone said replace thermostat and that would fix it, so thats what i did.

Lookin at vacuum fill kit from Harbor Freight https://www.harborfreight.com/cooli...MI9drjr5j2iwMVoWFHAR3Orzc5EAQYASABEgJLu_D_BwE
....but it says you hook it to radiator cap....So how would that work on mine?

You'd do it on the surge tank. I think they're a waste of money for these systems.

I did not....but i only thought that was necessary if you dont have a code reader to clear stored codes?

I asked because sometimes (not always) when the battery is disconnected the hvac actuators may goof up

ohhhhhh.....now that i think about it when i replaced it, i didnt disconnect it. However, after trying to figure out why it was doing what it did, i did disconnect for about 5 minutes....

So how do u "ungoof" them if thats the case?

Kinda starting to wonder if i may have a defective thermostat....

you could pull the hvac fuse momentarily that will cause it to recalibrate, but otherwise you need a scanner,
other options are to set the actuator to hot and unplug it and see if the same thing still happens or not, if not then you know it is the actuator or a interior temp sensor if you have the automatic control
