Does anyone out there have a link to a thread on how to remove and install freeze plugs? My search did not turn up anything useful. To save time, yes I am sure it is a freeze plug. I have been chasing a very small coolant leak for a few weeks on a fresh rebuild. I ended up putting some dye in my coolant and used a light on it to find the leak. It is coming from the bottom freeze plug on the back of the rear iron. I tested pulling a freeze plug out of an old iron I had laying around and got no where. I used the same tool you use to remove the pilot bearing. Any help on a "how to" would be greatly appreciated. RD
