Just wanted to let other members with the same Mercedes to look out for water loss.This was a follow up to my waterpump replacement that took a long time,over 5 weeks.Well all the coolant was put in and after some time i went out to check it to find the level in the expansion tank had dropped.Looking under the car i found this patch of coolant under drivers side of the car .As i looked , i could see it was running down from above.Up top it looked just like the head gasket at the rear of the engine block. I thought at that time thats it ,it parting out time. But then after looking again i found that the water was makeing its way out just above the head gasket ,from the rear of the back lifting eye.Now this looked easy,first caphead was removed ,o then i had a go at the bottom one.This was not going to come out easy.But after the little tap on the head with a 3 lb hammer it gave up.The part came off to expose a very worn 0 ring .Hope this helps every one with a rear coolant leak.
