Usually the thermostat doesn't get replaced with engine replacements it is either comes with the new engine or is transfered over from the old engine.
A number of components can cause an engine to overheat. Any air in the cooling system will cause overheat, a faulty or broken water pump will cause the engine to overheat, a stuck closed thermostat will cause overheating, and a blown head gasket will also cause overheating.
Is there a check engine light on? If so, what is the code(s).
Does the engine oil or coolant appear to look like a strawberry shake in color?
