Let’s think positive here.. All you have a a failed gasket due to age and nothing else.. It happens…
This is really a simple fix.. Drain about 3-4 gallons of coolant and follow the pics and advice on the link..DO NOT rethink what is in that article nor let a mechanic do that either………………… No rocket science here, just simple “Mechanics 101” ……
Bet you a 6-pack that if you inspect the gasket when its removed, you’ll see the issue.
