Hello. If the engine overheats this fast then you should do a block test. This sounds like a blown head gasket or a cracked head. When this occurs combustion pressure enters the cooling system and causes this to occur. I usually do a block test kit before anything else. This would be the only real reason why it would overheat this fast. If you need to have this repaired, consider YourMechanic, as a certified mechanic can come to your home or office to perform this test and accurately diagnose your overheating issue firsthand.
