This is likely going to end up a no win situation. Giving the customer money is admitting guilt, people don't handout money for no good reason. Here's a few possibilities of what is likely to happen. Even if the OP were to hand money out, odds are after the payoff the customer is going to say I brought my car in for service, the repair was botched I brought it back to fix it they blew up the engine. They paid me peanuts for my loss and I'm out a lot of money trying to replace the car now. Certainly not something I'd want to hear as a shop owner.
The OP could explain the reason for why he thinks it happened, then sit and wait to get sued. If sued let the judge determine who is right or wrong. Then pray the judge is a car guy with half a brain. Either way imo the customer is lost and he is going to tell his story regardless of what kind of goodwill payout he gets or doesn't get.
Or the OP can apologize, handout cash and pray the customer tells the story of how his engine blew up when in for repair service and the shop was great and paid him a bunch of money for his loss.
Final option is listen to the customer, explain the expert opinion of what you think happened, dig in and hope it goes away with no lawsuit. You can't please everyone and in business things like this happen unfortunately. The longer you're in business the more chances for something to go wrong. Odds are anyone saying they were in business for decades and never had a problem are probably liars.
Flip a coin, unfortunately any way it's sliced the OP loses. JMO
