I purchased a "new" TYC replacement alternator and it immediately started squealing after installing it. I called customer no-service and was told I could return the part for credit but it would be at MY EPENSE! I received a defective "new" alternator and then got the shaft - I had to spend just under $28 to ship it back. I protested to no avail. BUYER BEWARE- IF YOU GET A BAD PART FROM PARTSGEEK IT WILL COST YOU TO RETURN IT.
