way back when i was a messenger in my 88 ford escort...i put 300,000 miles on it and was never stranded...i always changed the accessory belt, timing belt and water pump at the same time..70,000 miles....the mechanics would give me a funny look..the water pump?..why?..its not leaking or bad....over the years ive seen plenty of cars and trucks dead on the road with broken belts and water pumps....so i did it b4 it happened..better safe than sorry...and oops........my belt on my v-10 is the original i think...130,000..ive been eyeing it for a long time..looks ok..but its gonna go this weekend...
