My sons 2001 ranger (auto) with 130k, overheated the other day. Inspection shows that after filling the coolant reservoir, the engine will leak it all out of the back. Between the engine and the transmission.
I originally thought there must be a heater hose connection there and either the hose has broken off or split open. But now I am reading that it could very well be a freeze plug that has corroded or fell out.
Here is a video of a mercury tracer where the transmission has to be removed to replace the freeze plug:
Anyone have experience with this job? How much of the trans removal job do you have to do to get at this plug? Is it easier to pull the engine? Any references on how-to links with pics would be appreciated.
