Parts and labor catalytic converter 2011 Chevy equinox


There is a federal warranty of 5 years on all catalytic converters. It should not cost you anything to have it replaced. You stated that it was a 2007 and then a 2011, which year is it? If it is a 2007, you are almost outside of the federal warranty.

How do I replace spark plugs and wires on chevrolet equinox 2011 2.4 liter front wheel drive


First, I think it highly unlikely that a 2011 Chevrolet Equinox would be due for spark plugs yet. They only have to be changed every 100,000 miles.

Second, you could spend the rest of your life trying to change the spark plug wires on that vehicle and never accomplish it. 2011 Chevrolet Equinox is not equipped with spark plug wires.

Then, if the spark plugs were somehow in need of replacement at this time, I highly recommend that you do not try this at home unless you have access to compressed air to clean the debris out of the spark plug tubes. Otherwise, severe engine damage can occur. (I have replaced many cylinder heads because of DIYers attempting to change their own spark plugs without the proper methods and equipment.)

With all that said, you must remove the ignition coils to get to the spark plugs.

Catalytic Converters, honda civic ex can I fix it instead buying a new one


no but because yours is flanged easy fix get a universal converter gaskets you will need some peices of exhaust take the old unit and the new one to a welding shop have them make you new one the same length as the old one and cut the flanges off the old one and weld to new one all this is probably cheaper than buying a direct fit converter

Install catalytic converter on 2005 chevy equinox


it will require some welding so you better off to let the muffler people do it. unless you are willing to tackle with it, then you need to cut the cat out then buy some pipe adaptors and some exhaust clamps.

How hard/easy to replace the OEM catalytic converter. Can you show me how. thaknk


The factory catalytic converters are welded in place. You can buy a replacement y pipe that has new converters or have an exhaust shop cut out the old ones and weld in new ones. Job can be difficult if exhaust has never been dropped before.
