The belt on my car was replaced at 90,000 miles in 1997. The car now has 113,000 miles. I have owned it for about 6 months. The car has been well maintained. At 106,000 it had a v-belt #7375 replaced and multi rib belt #6pk-1000 replaced. Do I need to worry about the belts yet? Is there a way to check? I don't have much experience with these cars. I have had a 914 for years but drove 944 turbo and loved the speed and handling so now have both. The car is a 1986. thanks John Elliott
