I purschased ATATEXAN's 300SDL. It was delivered Sunday. I am excited!!

And the questions begin in 3 . . . 2 . . . 1 . . .

The car loses coolant. PO said that there would be a small puddle on the floor. He had the radiator and all hoses replaced. Don't remember if the water pump was replaced or not. The system was pressure tested and passed. Where could the coolant be going? My first thought is to replace the expansion tank and cap (puddle is on that side of the car). Any suggestions?

The oil cooler lines leak (slightly larger than silver dollar puddle after 20 minute drive) and appear to need replacing. I looked at them and they appear to be straight forward to replace. IS this wishful thinking on my part? Should I let my indy replace them? Anyone have any comments or suggestions?

That's it for now . . . more to come!
