For a 1994 Pontiac Sunbird with a 2.0-liter 4-cylinder engine, the frost plug (also known as a freeze plug) typically has a diameter of 1.75 inches. However, it's always best to verify the size by checking the specific service manual or consulting with a parts dealer to ensure accuracy, as variations can occur.
I have a 1990 Pontiac sunbird and i was only able to find one, it was behind the exhaust manifold on the block. I myself am having problems finding the other. I hope this helps.
