C3 1971 Antifreeze Leak, Need Help!

[Dale P.]

We have a antifreeze leak on the passenger side rear freeze plug. The system can be pumped up and will hold pressure but we get @1 teaspoon of leakage everytime we run the car and return home. In your opinion, should we replace plug or leave it. Do you have to pull the engine to replace plug?

Easy replacment! These plugs are made to be replaced every time you cleanout the coolent. Let your local mechanic do it for you.

this is not an easy job and they were not made to replace every time you replace your anti freeze. they rust because of no antifreeze in the system. if you have one leaking in the bellhousing area you will need to drop the trans. if you replace any reinstall brass ones. good luck.
