I changed the coolant temperature sensor. Then I drained the coolant fluid from the now it won't let me fill it up through the reservoir. It doesn't seem like it's taking enough coolant into it.

Sounds like you have an air pocket.

I attached the procedure from the manual for your review. Let's run through that and see if there is anything you are missing.

If not, how long are you running the engine before you are trying to add more coolant? Also, does it overheat?
