The radiator I bought from rockauto was a non-oem brand and it dropped right in perfectly with no leaks esp at the transmission cooler lines and ran at the correct temperature.  
Funny thing is that rockauto had the lowest price by far on a radiator for my '95 Volvo 850 GLT. Ha.  
I think I may shop more at this website for parts.

Rock auto has the best prices anywhere. They ship quickly and I have never got the wrong part.

Rock Auto blows away the competition in speed, accuracy and price. Their on-line catalog loads quickly and provides an illustrated parts guide to make sure you order the right part. The catalog itself is easy to navigate and not filled with burdensome pop ups, or annoying banners and excessive java scripts. The interactive catalog is lean and mean, responds instantly and is a model of how all on line catalogs could be more efficient.  
I have yet to find an error in the catalog, if you have a complete vehicle description - they have the correct part.  
Shipping has been so fast from the East Coast to the West Coast, I'm often caught off guard by the Fed Ex or UPS truck showing up days ahead of my estimate. When the order is placed, they don't waste time filling it. My invoices often have hand written notes on it - showing a real person has double checked the order for accuracy. Unbelievable in the age of outsourcing everything, this business actually cares about getting the job done right the first time.  
Some how, Rock Auto can offer substantially discounted parts from wharehouse close outs. Rock auto just saved me over $60 on two Subaru transmission seals. That's not just amazing, it puts the competition to shame and makes me wonder what the mark up really is on some parts. Since I have discovered Rock, it has become my primary parts source for all my vehicles. I check Rock first, the only way I would ever buy something elsewhere is if Rock did not have it - but the thing is; I haven't come across anything that Rock doesn't have.

Excellent products, very quick shipping, Rockauto is now one of my favorite places to shop for my car.  
Thank you for providing such good customer service.

Really good deal! Found great price on hard to find products. Will definately purchase more as needed!

Absolutely the best prices on auto parts, bar none! I was buying from autopartswarehouse.com and doing better than local parts houses, but rockauto.com has them all beat. reasonable ship times, too. The only reason I would go elsewhere at this point is if I couldn't wait for shipping. rockauto also shows you when your parts are coming out of multiple warehouses before you complete the order, so you can make changes to your order, condense it down to a single warehouse if possible, and save on shipping.

Excellent customer service, easy to deal with on the phone, one of the most informative and easiest websites to use, very satisfied with quality of part

I've dealth with RockAuto on several occasions and they are terrific! I had an issue with the wrong part being sent and they couldn't do enough to get it corrected quickly. Their customer service is great and so are their prices. I dealt with another place that had slightly lower prices and it was amistake. I should have paid the couple of extra bucks and stuck with RockAuto.

Just have to say rearley these days am I impressed by a company but Rock Auto has restored some faith. I ordered a part that was urgently needed for my F350 in the UK. On the 17th June I placed the order and by the 22nd June I had it in my hands.And at a price that made me feel like I had, had a bargain considering an English company had wanted nearly $500 more than I had paid from Rock Auto's. Just have to say thank you very much and I will be a returning customer.

Best Prices, great selection of parts ,only wish they offered the option to use UPS instead of just fedex.

Excellent selection of parts, quick service and great customer satisfaction.

I received the auto part, a plastic lamp cover but it's broken during shipping. The reason why it's broken was it's shipped in paper envelope. Though the packaging is really bad, customer service responds promptly.

Rock Auto has and is a quality run business. I have shopped here in the past,present and will buy from in the future. Prices are competitive,shipping could be cheaper. Why do we as consumers have to pay for different Warehouses that Rock Auto ships from. It should all be one price. Not my fault that it isn't shipped from one location. Other than that produts are quality. Thank you Rock Auto.

Rockauto is a great company to deal with. I always have the parts in hand very quick and the price is unbeatable. I have recommended them to all my friends and family with great success. No complaints from anyone. Research discount codes and get an additional 5% off. Once you are a good customer they will send them to you. But they are out there on the web.

Have been a customer for several years. Have never been disapointed with service or delivery. Returns are a snap as well. Excellent company to do business with. Wish they were all as good as RockAuto.
