I replaced the water pump on a 96 Z24. Had to remove the Timing chain
cover, timing chain tensioner, harmonic balancer, exhaust manifold, at least
one engine mount and support the engine. Had to raise/lower engine to get
to some screws. There are two holes to insert pins to keep the camshafts in
proper time. I had the pleasure of again adjusting the timing chain after
the pump was replace but somehow I let the timing get off for one camshaft.
Service Manual allows dealer 5.3 hours to change the water pump. Be
prepared to work on it awhile.
Suggest you buy a service manual for the car.
