I have a 360 Spider. What is intervals for: Waterpump. Timing belts. Oil+filter. Spark plugs. Air filters. Also. Any extra I should change? Is it normal to change waterpump on 360 during timing belt change?
This is very clearly laid out in your owners manual I suspect it has also been spelled out here numerous times too - might be worth taking a look
