Coolant Leak
« on: September 10, 2020, 07:45:53 PM »
My new to me 79 403 TA seems to be leaking a small amount of coolant on the ground under the starter.  I can't figure out the source... it appears to be dripping onto the starter.  Any ideas on wherr the leak might be coming from?

Could be a welsh plug above it.

Does the motor have to come out for this job? 

I also have what I think is either a small rear main or pan oil leak, so maybe it's time to have the motor pulled rebuilt?  It's a 48k original mile car... was hoping to get a little more out of it before a rebuild but I guess this is how things go sometimes.

Depending on the location the motor does not have to come out. Sometimes it just has to be raised a little of the engine mounts. They used to make freeze plunges that could be installed by tightening a nut causing it to expand, good for tight spaces.

if you go with the "expandable freeze plug" it is highly recommended to disassemble the "plug" and coat both sides of the washer with SILICONE gasket sealer BEFORE you install it into its new WET environment.
