How do you replace a rear main seal on a 1995 Chevy beretta v6?

To replace the rear main seal on a 1995 Chevy Beretta V6, first, disconnect the battery and remove the transmission to access the engine's rear. Drain the engine oil and unbolt the oil pan to remove it, which may require disconnecting the exhaust system and crossmember. Once the oil pan is off, remove the old rear main seal from the crankshaft, clean the sealing surfaces, and install the new seal carefully. Reassemble by reversing the disassembly steps, ensuring all components are properly aligned and torqued to specifications.
