350z radiator replacement review
I purchased an oem replacement radiator from iaauto since mine was leaking. Shipping was pretty fast and packaging was good. I replaced it in about 45 minutes. The radiator fit perfect but it did not come with a radiator cap and there was an extra two hose nipples on the bottom of the radiator that I had to cap off since my car didn’t have those coolant hoses. Other than that everything else bolted up good.
