2005 Ford Crown Victoria Q&A
2005 Ford Crown Victoria Question: replaced one catalytic converter and now the second one is making loud noise.
i do belive fed law is 70k miles or 7 yrs you might be under warrnty. call the dealer - globalhelper
Your car is equipped with two coverters on each side (4 total) was tthe 'one' that was replaced done at the dealer or did an aftermarket shop cut and weld in a single converter to one of these assemblies? if that was done , it may void any warranty (at least on the affected side).Good luck. - ziptie12
