coolant leak

[KIKER]

I have a coolant leak that I have noticed dripping off the flywheel dust cover. It doesn't leak all the time. I noticed it was dripping after being shut down for about 36 hours. My drive way is on a slight slope and sometimes I back in and sometime I pull in. One time it started dripping after I started it up and moved it to the street, which is fairly level. It was dry on the drive way. I think my overflow tank is about empty now. Could it be the tank itself? Are there any freeze plugs behind the flywheel? I noticed a short hose on the passenger side of the engine, but didn't see any signs of leakage. Any suggestions on where to start looking? Thanks.

While the expansion tanks seldom, leak, often the hose that goes from the radiator to the tank has no clamp and begins to leak at the radiator side.

Also, another common leak is the coolant hose that goes to the block, just behind and under the turbo. There is an upgraded hose and clamp for this part.

A VERY common leak is the water pump weep hole is located above the main crankshaft/harmonic balancer and starts to leak as the pump seal and/or bearings go bad, but that is at the front of the engine, not at the flywheel.

Dollar to a donut, it's the short hose you referenced before. That is a very frequent source of a small leak, especially one that shows up in that area. Parts are fairly cheap but it's a real nuisance fix.
Just tightening up the clamps might buy you some time with it.
