The noises that you heard (squeaking) was the engine wailing in protest of being way over-heated. The clunking noises you heard was the engine slowly cooling off and contracting. If you had blown the radiator, you would/should have noticed steam and a leakage of coolant. Instead of shutting the engine down immediately, you should have turned on the heater, as the heater coil is a miniature radiator, that can cool engine temps by 15-20 deg F. Right now, your biggest worry should be a blown head gasket or a cracked head/block. Look for oil/coolant leakage. Look for coolant in the engine oil and/or oil in the coolant. Contaminated engine oil will be a foamy brown - check after the engine has run up to operating temps. Another possibility - if equiped with electric cooling fan - the fan has failed to run. This is attributable to several factors that range from a blown fuse to a toasted fan motor. -- When a person delegates their responsibilities to another, that person loses the right to complain about the misuse of those responsibilities. -R.
