I have a 2007 Dodge Caliber 2.0
My car keeps overheating...had a pressure test done And no coolant is leaking! Sometimes my heater won't work when it's overheating! I don't know where to start! Had the computer looked at said it was engine coolant problem

Well, if in fact you are constantly adding coolant, then the coolant is either leaking out or its burning inside the engine. There are no other possibilities for the loss of coolant.
So either the pressure test was not done thoroughly enough (or the inspection) or you have a head gasket issue.
With low coolant, or lots of air blockage in the system, your heater will not work, that's correct.5

Thermostat is probably stuck closed, or open.
Either give us more information (under what conditions, how soon after started, typical driving behavior, miles, ec) or bring it to the dealer.
it over heats within less than a week of me putting coolant in! I don't know where the coolant is going it's not leaking anywhere that I can see! When it overheats my heater won't work! So assuming it's a thurmostate issue....go figure there is two!
