Manufacturer's Rebate Instruction


Rebate Tips
1. Read your Pep Boys rebate form thoroughly. Each Pep Boys rebate offer is unique, with different date ranges and postmark date requirements. Many rebates require the purchase of multiple products. You must submit all qualifying products listed for a given rebate to be eligible. The best way to make sure you get your rebate is to follow the instructions carefully. If you have any questions, call us at the toll-free number listed on the rebate form or call your local Pep Boys store.

2. Make copies of all of your paperwork. This includes your receipt, rebate form, mailing envelope, and any other items that are needed for validation of your rebate. If for some reason your submission gets lost in the mail, you will need this information to have your rebate reprocessed. It is also a good idea to have this information in front of you if you need to call the customer service phone number listed on your rebate form.

3. Don't wait. Many Pep Boys rebates require your rebate submission to be postmarked within a set number of days from your date of purchase. If you miss this deadline, you will not be able to receive your rebate.

4. Clearly write your name and address on the rebate form. If your handwriting is difficult to read, it will be difficult to enter your information correctly. To ensure fast, accurate processing of your rebate, be sure to print clearly. Remember also that PO boxes are not acceptable addresses for Pep Boys rebates, so be sure to include your street address when you complete your offer form.

5. Watch for your rebate check in the mail.

Road Hazard Warranty

Protect Your Investment
What will our Road Hazard Warranty do for you?

Repair
Pep Boys will follow its Puncture Repair Procedures to determine if your tire should be repaired, at no expense, or replaced under this coverage. While the repair cost is free, there will be a charge for re-balancing a repaired tire.

Replacement
Road Hazard Warranty can save you the expense of tire replacement. If your Pep Boys tire becomes unusable due to a road hazard related mishap and cannot be repaired, we will, subject to pro-rated adjustment based upon the remaining usable tread on the tire, replace the unusable tire or give you a refund. While Pep Boys will remount the tire for free, there will be a cost for re-balancing the replacement tire.

Coverage extends to such damage as unrepairable tread punctures damage from potholes, nails, glass and jagged metal which cause cuts, snags, punctures, impact breaks, bruises and rim cuts.

Length Of Coverage
Coverage with Road Hazard Warranty extends for the full period of the mileage of the tire. This coverage is not transferable to a new owner, or if the owner mounts the tires on another vehicle.Close [x]

Core Charge

A "Core Charge" is similar to the deposit you might pay for a can or bottle of soda. In many states, to promote recycling, you are charged a deposit when you purchase a can of soda and you receive your deposit back when you return the empty can. Many automotive parts have a Core Charge, or Core Price, that works the same way as a soda can deposit.

Here's how the Core Charge works:
  • The part you are purchasing contains a component that is recyclable
  • The Core Charge deposit is charged at the time of purchase
  • When the recyclable component from your old part is returned to us, the charge is refunded to you
  • To receive your Core Charge refund, you can do either of the following:
  • Bring the part to any Pep Boys store along with your receipt or invoice (recommended)
  • Mail the part back to Pep Boys through the online return process
  • Please see our Returns Policy for more information on returning a core item.
Core Charges are often mandated by state legislature, and, as such, the actual core charge and taxes on the charge may vary depending on the state in which you buy your part. The Pep Boys core charge presented to you online today with your item is representative of the most common core charge. If you have any questions, please contact our Customer Care Center at 1-800-PEP-BOYS (737-2697) or visit any Pep Boys store. Close [x]

Mr Gasket CataClean Cataclean Engine and Catalytic Converter Treatment- 16 oz. 4.2 5 5 5
CATCLEAN This product seem to work>I used on the Mustang 3.9 V6 2004 I noticed no more condensation in tail pipe and different less offensive odor or exhaust smell. If it helps to clean the CAT because the cost can run into thousnads to chang out the CT System. Used on mustang first and then and on 2003 ford 5.4 SUV last week. Waiting until I need to fill tank up before I make any comments September 3, 2013
Works as advertised Followed manufacturer directions and check engine light and cat code are clear. Would recommend highly. Beats expensive and usually not required cat replacement. September 1, 2013
The skeptic says this stuff works! For two years, my check engine light has been coming on intermittently, consistently for the last year or so. Car was throwing P0420. On a recommendation from the inspection station after my car failed, I sought Cataclean out from my parts store. I wasn't ready to spend $1500 on a new catalytic converter and $25 was worth the risk. The car is a 2004 Honda Civic, well known for having a pretty sensitive set of sensors and some risk that replacement converters don't necessarily work every time. 102,000 miles just didn't seem like a long enough life for the converter in a car that could potentially get 300,000 miles in its lifetime. The P0420 at it's worst occurring as a pending code within a few miles of being reset, typically just after the EGR test had passed. Within a few more miles, the P0420 would occur again with the catalytic converter test causing the check engine light to stay on. With a scanner, I could see that the engine was throwing it at about 1700RPM, where a year ago, I could keep the light off if I kept the car below 3000RPM while it ran through all of its emissions tests after a code reset. The first time, I followed the instructions and saw a small improvement, but not much. The light started coming on at about 2100 RPM this time, so it was moving the right direction, just not far enough. I did purchase a second bottle and went well beyond the instructions, running it in my tank for about 100 miles before filling my tank up, mixture of highway and city driving over a few days. Then I cleared my computer codes. Shazaam! The light is off and the computer is ready for a passed inspection. Total cost of repair: $52. A much better investment in my mind. It just took a little patience and trust that it could work! My advice to any user of this product is if you're going to use it and the converter is looking bad enough to replace, run it way beyond the instructed mileage because there is clearly some work to be done. Let it do the work. If you have access to a good code reader, it'll help you see the improvement. August 30, 2013
This product is a waste of time and money. I know better than to get mixed up with some chem tools. Don't get me wrong. I'm sure this has some engine matienence value. But really. July 29, 2013
It is a miracle. Bought Mr. Gasket Cataclean Engine and Catalytic Converter Treatment 16 OZ. I followed directions on the bottle and it worked just as advertized. My 2001 Astro van runs and idles great. I will use this treatment in as preventive maintenance in the future.I bought this at PEP BOYS. Paid for it online and my wife picked it up the next day since I worked all day. July 4, 2013
