I would run a Delco, But they are not hard to change & I havent had any problems out of NEW aftermarket water pumps. Stay away from reman pumps.

Ive only seen 1 or 2 of these pumps go bad (leaking from the weep hole/bushing failure). But have replaced to many water pump to block gaskets to count. Check it out, Gaskets are cheap.
