Location: Suwanee, GA | 1962 New Yorker with 413:
I replaced the leaking middle, passenger's side freeze plug, but two others are leaking, so I should probably replace them all. I know I can remove the remaining ones without difficulty, but is it possible to reinstall the front ones near the motor mounts without removing the engine from the car? I have a cherry picker to support the engine if I need to remove the mounts. What have you guys done? These are the cup type plugs. ...and unfortunately I don't have a lift.
Thanks,
Robert |

Location: Newark, Texas (Fort Worth) | I had a leaker behind the motor mount on a Poly. I supported the car, put jack and board under the harmonic balance ring/pan and took the weight off, removed the engine mount, replaced the freeze plug, put in a new isolator while I was there, painted it and put it all back together.

Location: Suwanee, GA | Thanks Marc. This was enough to motivate me this morning. Got the passenger's side replaced. And while I was at it, I found out the flat part of the motor mount that attaches to the frame was sheared completely off. I'll take it to work tomorrow and have one of our welders weld it back together for me. I have a feeling there's a surprise waiting for me on the driver's side.

Location: Northen Virginia | you can change the plugs with the engine there but it is a challenging job and required the correct tools... |

Location: Pacific Northwest | I ended up pulling the engine. Replaced them all and repainted the engine back to the correct turquoise color. Now I am waiting for transmission lines to replace the ones I trashed. |

Location: Northen Virginia | Best decision ever, as you probably know now, do it with the engine in the car was not a good idea.. |

Location: Suwanee, GA | I should have posted earlier. I got them replaced, but boy what a pain. I cleaned out a lot of crud in the process. I had a welder at work fix the broken motor mount. He welded it under water to prevent damage to the rubber. Driver's mount was fine.

Location: So. Cal | Welding under water....never tried that. Sounds like fun.
I replaced the freeze plugs on the LA 318 in my '70 Satellite. The back 2 were easy as pie. The front were pure pain as the K-frame is just in the way. But I got it done and it was easier, in the end, than pulling the whole motor out. |

| I've also used the rubber plugs for years, in chevys and internationals. Could never get
the right angle to pop the stock ones in and they would just pivot and egg while motor
was in the car. I know it's a bandaid, but never had an issue, even with the rubber part
extending into the block. Have several in my Desoto. Perry. |

| I replaced all of the plugs on my 66 T&C 440 with the engine in the car. Front motor mounts needed to be removed, and a slight lifting of the engine. What made it successful was buying a freeze plug installation tool kit like this:

The angle tool plus exact fit inserts for the plugs made this fairly easy.
