What are you spouting off about? It IS free to have us sit here for hours on end with our noses in service manuals that we buy ourselves doing research you are too lazy to do yourself; all for your benefit. Do YOU work for free? If not, why not? We do. I type very long answers to over 25 people each day, ... ALL of them with no donations. Yours is no different. If you don't get an answer it's because you didn't give enough information or details or no one understood the question or knew the answer.
The recommended replacement interval is spelled out in your owner's manual or the dealer can tell you. You couldn't even be bothered to list which engine you have. That makes a difference but you apparently think we're psychic. Some engines use a timing chain instead of a belt. Some engines are not damaged internally when the belt breaks so regular replacement just for maintenance is less critical. Most import engines are of the "interference" design. Valves get hit and bent by the pistons as they coast to a stop when the belt breaks. That turns an expensive maintenance repair into a REALLY expensive repair with a tow truck involved. 75,000 miles is a common recommendation interval, but again, WHICH ENGINE DO YOU HAVE?
Now, if you'll excuse me, I have eleven grateful people, all who made no donations to help me out, who I need to continue previous conversations with. Not one of them is complaining and they deserve my time.
