How to Remove an 88 S10 Blazer Catalytic Converter
The catalytic converter on your 1988 Chevy Blazer is located in the exhaust system and is a critical part of the emissions control system for your engine. The design of the converter will reduce pollutants like carbon monoxide and unburned hydrocarbons and stop the escape of these pollutants from the exhaust system. A catalytic converter does not have a life expectancy and should not fail but if it does, the first step in repairing the system is to remove the converter for inspection and possible replacement.
Instructions
- 1
Raise the front end of your Blazer with a jack and support it with a set of jack stands positioned solidly under the frame of the truck. Remove the jack from under the truck so you dont have to try and work around it.
2Locate the catalytic converter in the front of the exhaust system. On the S10 Blazer, it is located just behind the Y pipe where the two down pipes from the engine come together.
3Locate the two mounting bolts on the joint at the rear of the catalytic converter where it meets the exhaust pipe. Remove the bolts with a socket and ratchet and then separate the joint.
4Move to the front of the catalytic converter and locate the tow bolts that attach the converter mount to the front of the converter. Remove the bolts with a socket and ratchet. Remove the exhaust clamp just in front of the mount, using a socket and ratchet to remove the nuts from the cl then separate the two halves of the clamp.
5Separate the catalytic converter from the front pipe by pulling it straight back, using a twisting motion to loosen the catalytic converter from the pipe. Remove the converter out from under the truck and set it aside.
