Your 2007 Corolla DOES NOT HAVE A TIMING BELT. Older Corollas do.
I have a 2007 Corolla and follow the owner’s manual, not what the dealer is trying to tell me.
Aside frorm oil changes, which I do every 5000 miles, the car had had a cooling system flush at 48,000 miles, and will have a transmission drain and filter change (the second one) at 60,000+ miles. Tires are rotated seasonally with winter tires going on in October and taken off in April.
The car runs like new and has only had the front brakes done and the serpentine belt replace. Current mileage is 61,000.
Spark plugs don’t needed changing till 100,000 miles.
You are driving one of the most bullet-proof cars ever built; keep on motoring.
