RockAuto generally have a number of brands for sale so you can compare the price, description and the picture. I tend to buy AC Delco if the price is reasonable. I recently bought an AC Delco water pump from RockAuto for my 84 and it was fine. One thing to note the pump didn’t come with the heater hose fitting and that fitting is longer on a corvette than some other chevys.

If your car has no "cooling issues" then use a stock replacement. If your car runs hotter then you might want to have more flow. I purchased an Edlebrock aluminum Pump as it works well on cars that get hot. The aftermarket pumps have better impeller designs that work more efficiently and frequently flow more coolant.
Don't use more anti-freeze than you need for your area of the world, here in Virginia I use 70% water, 30% anti-freeze. Water is better than AF at transferring the heat so the more water you have the better it will cool. Also be sure to change the hoses, clamps, radiator cap and thermostat while you are at it to make the job and your car last longer.
RockAuto is a great source of stock parts! Their shipping amazes me, never more than 2 days and you get the right parts.
Be careful though, RA shipped me a "New" AC Delco MAP sensor for a car I own and when I got it the box contained a "used" part in the new appearing box. When I approached RA about this they accused me of trying to pull a fast one on them. I sent the "New" one back to them and have not received a replacement or refund in over a year now. They told me that they don't take back "used" electrical parts, they sent me a "used part" in a new box so somebody pulled one over them. I am out the $40 for the part and shipping and then returning the part to them. I am not happy about this mess but suspect it is never going to be resolved to my satisfaction. Buyer beware! Why are they willing to give up a long time customer who has spent literally several thousands of dollars over some part that was returned to them and put back on the shelf without checking the parts first. The MAP sensor was oil and dirty and obviously a "used" part. By the way, it was a dead MAP sensor they sent me. This is STRIKE 1 for them, after two more I will give up on them forever and pay more just because I don't like the way they treated me on this matter.
I hope you all have better experiences with the folks at RockAuto!
I went to NAPA and bought a new one from them.
Best Regards,

I gave up on RA as their prices aren't that much better when you account for all the shipping you get charged for now. You buy 3 parts they come from 3 separate warehouses unless you want to get stuck buying a brand you don't want because it is in the same warehouse. They were good about taking bad parts back but I also started getting more bad parts than it was worth. I'm starting to think they get the "seconds" from manufactures or something. Example:
- Needed a waterpump for one of my cars. Ordered a Cardone re-manufactured unit. Part comes in and the mating surface wasn't machined and was as rough as the casting was. Replaced with RA and the 2nd one was the same. Replaced again by RA and the THIRD was the same. I started to think that it was Cardone. Went to local parts store that had one in stock (think it was an O'Riles) and they opened the box. Was perfect.
- Needed a waterpump for my corvette. Ordered from RA. It looked good so I installed it (don't recall brand). Leaked real bad. Thought I messed up install so redid with new gaskets. Same thing. Leaked just putting coolant in the car. Took the pump off and took my straight edge to the mating surface. Sure enough, it was cupped.... RA wouldn't accept this return as it was installed and because it was a couple months after purchase, moved to a new house.
Same things with all kinds of other parts now. I spend a little more now and get my hands on the part before buying. No longer have to deal with shipping stuff back and forth anymore. I used to LOVE rock auto but now I refuse to even look at them.
One key note as well. Water does cool better than Coolant but your protection is in the coolant (not just for anti freeze needs). The additives in the coolant does a lot more. Not an issue to run lower than 50/50 but if you do, I strongly encourage you to change your fluid more often.

Well, I've never had a problem with Rockauto in the last 12 years, I've sent a few bad parts back over the years and all went well. I replaced every coolant part except the water pump and heater core, go figure the pump goes out after two months. Just finished the harmonic balancer on the C5Z,,, It never ends

When you find the part you want on RA, copy and paste the part number to Amazon. I've bought the same parts from RA off Amazon much cheaper and with free shipping on several. I bought the same AC Delco water pump you're looking at off of Amazon for $86 last October. and depending on the year of your car, don't forget to add a weep hole drain to preserve the opti.
