View Full Version : 100 Hour Service

07-04-2012, 06:20 PM
After checking around, it seems most every service shop does different things for 100 hour service. What SHOULD be done for a 4.3 Alpha? Quotes range from $200-$500. All that's been done for annual service is changing fluids and I/O gaskets. This will be the first actual 100 hours on the engine, what else? (I do not have an owner's manual) Thanks!
