havent driven the 62 for 2 days and today noticed a small puddle of coolant dripping directly under the cat thats closest to the drivers side. probably 10mL of GREEN coolant, which is wierd because the radiator was flushed a week ago and the new red coolant was added. ??? the coolant in the fill bottle is still red and when i opened up the rad. cap it was red as well and full. Started the engine and ran for a few mintues but no leak. i thought it might be the rear coolant engine drain plug but if that was loose it would leak on the cat closest to the passenger side. leak is hard to trace and i think the only reason why i noticed it was its been way humid here in SD so the coolant leaking on the ground hasnt been able to evaporate. any thoughts?
