What is a possible problem to an overheated engine of a sunfire 2.2L after driven while overheating say 20mi?

Question

I drove about 20 - 22 miles. The serpentine belt broke from a damaged idler pulley. So I started losing antifreeze.

Answer 1

The other answer thinks those bottles of expensive gunk work like ten thousand nanomechanics inside your engine giving it new pistons and rod bearings and it will even un warp heat dammaged Cyl heads. You will be lucky if the engine escaped dammage just water and oil levels put a new belt on and idler pulley it start the engine. If it runs and drives does not loose coolant leak out oil fron a overheated head gasket. Also does it restart from cold or liquid lock from water inside the cyl. See if it is worth changing the oil and adding dexcool antifreeze. How many months was the idler making noise?

Answer 2

Drain engine oil, and change oil filter. Put 1 quart slick fifty, and the rest of oil should be - Mobile One Synthetic Whatever - weight your manual calls for. Replace idler pulley, and belt with a - Gates belt. - Replace antifreeze, and add a bottle of the - Most Expensive bars leaks block seal. - Start the car, if any knocking is heard, add a bottle of No-Smoke, drive directly to car wash, spend ten dollars washing the engine undercarriage, and wax the darn car, on a SATURDAY before noon. " I say before noon, because the car sales people are still hung over from Friday evening." Drive to the NEARET shisty used car dealership and trade it in on a Toyota.

Answer 3

not much to add to this but, why would you ruin a car that was warning you that it was overheating? thats what the gauges and idiot lights are for.
