Thread: Taking forever to warm up

Looking for a cheaper place to flush, someone suggested Wal-mart... do you think their shop would do it correctly? Guy says thermostat seems to be working fine. Thinking of just changing it anyway with some guys from work who have done it before to supervise.

If that doesnt work would it be a heater core problem, if so how long of a job should it be to replace it? Have some names to call of guys who do side jobs out of thier shops at home.
