It would be prudent to replace the opti-spark, also. Here is one source for parts: http://www.partsamerica.com/ You might reference the C4 TECH TIP forum on the replacement of the opti-spark and pump, and take advantage of the experience gained by other members.

Ditto on the Opti-spark. Be sure to disassemble the new opti and reseal with some hi-temp RTV. Take a look at your old one, you'll see why.
Be sure to use thread sealer on the water pump bolts, they go into the water jacket.
Contact Jeff Kopp at www.superchevyperformance.com (a forum supporting vendor) for excellent prices and service.

:iagree:
Just finished this mod on my '94 and was surprised how trashed my Opti was with just a "minor" water pump leak. The seal was shot and the bearing and internals were all rusted and tracked with dust & road grime. It was amazing to me that the car was even running! You'll save yourself a lot of headaches down the line if you replace them both now....might be an opportune time to pull that radiator shroud and do a clean up on the rad (just my $ .02).
Good luck

I agree with the other folks You might want to think about venting opti also, I did mine. I went with gm water pump I don't know if napa is better or worse. Sure is cold here huh! :cheers:
