2000 D2 120k miles

Car didnt start. I changed Crankshaft position sensor.

Still didnt start so I did a tune up, changed old battery.
Still didnt start, changed fuel pump


Starts, I drive off lot for 2 miles and car over heats and I loose LOTS of fluid underneath car.
Mechanic says my lower radiator hose exploded so he changed it for free.
Next day the car only goes in reverse not in drive.

Something is seriously wrong so Im talking my car to Boston Roverland.
Does anyone have any ideas. I have spent $2k in the past 2 months and I still dont have a car.

 

This could really be a long conversation, If you want some help, send me your number and lets talk thru it.
