Hi all,

Background info; An 83 300 D w/145K. Fairly new radiator and fan clutch and t-stat, all within 4000 miles, waterpump was replaced 55k ago, no coolant loss although car would at times run slightly warm, up to 100, even in cool weather not using A/C. Normally, this car runs about 85.

Yesterday, I installed a new t-stat, only to find out today that I had installed it backwards. UGH! Engine temp last night went to 110! At any rate, after correcting the problem today, I now have 2 external coolant leaks. One appears at the transmission! it drips down almost out of the little hole down there. The other location, I cannot determine, kind of near the starter?

The leaks are coolant, as the resovoir has steadly lost its contents from today. All connections/clamps/hoses and t-stat housing appear dry. The car never ran warm today. Head gasket appears fine. Oil appears ok too, level is at least the same as it was yesterday. Hope I didn't really cause some damage yesterday evening.

Anybody experience this? Other comments on where these leaks might originate is appreciated.

P.S. Forgot to mention that I replaced the temp. sensor last week, resulting in no changes.
