Replace the fan clutch that is on the front of the engine.
That would be the 5.7L / 350 Vortec.
It is screewed into the top of the engine block just behind the distributor.
It is a 4L60E
5.7 liter 350 and the 6.5 liter diesel
No it will not. The 96 and 97 transmission bellhousings are different.
YES The above answer is right. But the problem is that you will have to change the 97 computer,fuel pump, Engine and transmission wireing harness. You will also have to put the 700R4 transmission in that 97 Tahoe. Reason being is that the 91 computer that you HAVE to use won't shift the 4L60E that's in the Tahoe now. Your best bet is to put a VORTEC back in the Tahoe.
A diagram for a 97 Chevy Tahoe shifting assembly can be found at Rock Auto. This can also be found at Twin Charlotte.
junk it
They both use the 4L60E.
do you mean it cranks, but will not start?
YES, if you know what you are doing. You will need the complete engine and transmission wiring harness and computer plus the fuel pump for the 5.3L engine. The wiring harness and computer on the 97 will NOT work.
Ford and Chevy parts will not interchange, SORRY
