White smoke coming out of the tailpipe? May be headgaskets.

Boiling coolant in the reservoir? May consider replacing the radiator cap.

Ditto with MCE. It probably overheated & blew up before. At any rate it's overheat now & probably blown up. They're giving you the good advice.
Start by replacing BOTH pressure cap[s, checking the thermostat again, and THEN warm the engine up & do a compression / leak down test to see if it's blown up.
