I have been doing business with 1800radiator for some time but since they were sold the new owners will not honor any manufacturer warranty, I installed a catalytic converter on a 2012 jeep Patriot with a 2.4L if anyone has done one it's not pretty anyway converter went bad after 6 months after completing the job for the second time I called for pickup of the warranty part and asked what do you need for the labor warranty, LOL joke is on me... they don't cover labor warranty 4.5 hrs down the drain. They will never sell me another part ever. Rambo's Autoworks Penns Grove NJ
