First question is : I have a 94 caprice classic 4.3l witch came with a oil pump with no oil cooler lines I installed a 95 impala ss 5.7 and the oil pump came with cooler lies my radiator or water pump do not have cooler lines so should I buy a new water pump and radiator or is that optional? Because my 94 ran with out the cooler lines before without them.

second question is: will my 94 caprice classic 4.3l computer read the new 95 impala 5.7 engine I installed? Will it be cheaper to reprogram or just buy the computer?

thank u 4 tha help

First question. The oil cooler lines plug into the block area be the oil filter on that engine, so all you have to do is buy the oil cooler lines for a 95 SS impala and then the radiator for the same, and it should all go in no problem. The problem will be with the computer systems. The 4.3 wiring harness is nowhere close to the harness for the 5.7. You will need to swap the entire wiring harness for the PCM. The trans should be the same (4L60E) for both cars, so the harness should be ok for that part.
