I think my motor is sucking coolant like crazy, and i don't see any leaks. is this usual or do you guys think something is leaking?

Any white smoke from the exhaust? Have you done a compression test? If it is dissapearing and there are no leaks, sounds like it could be a head gasket. Have you checked the heater valve though located behind the throttle body down on the firewall? I had missing coolant for about a week before I realized where it was going and that little plastic valve had a slow leak.

 

There might be some white smoke. It was really cold last night i don't know if thats what it was. Ill have to pay more attention.
