Cooling System Maintenance Inspect Exhaust System All exhaust system components must be inspected whenever the exhaust system is disassembled. Check muffl er mounting Dirt or debris can restrict air fl ow and cause the engine to bracket and/or muffl er adapters for cracked welds or break- overheat, resulting in poor performance and reduced engine age.
