[dgerlach]

Hello, ALL
Just picked up a d24 motor yesterday. MY older motor of 289K miles is going threw head/coolant problems.
Now that I have it ,What is it? The number under vacuum pump are stamped CW110100 block number, alumn. head casting number is 072103373. and air intake casting is 07129713A. pump is a bosch 0460 40 6 033 ve 2 146. Not sure if these are the correct numbers. Want to clean it up. set valves and maybe new head bolts and new belts.
I have had this 85 volvo since 89' .....LOVE THE CAR.......
want to know.... What I am going to be powering the car.
