I hate this but Im not sure. Okay the serp belt on my car is make ****ty sound and I need to replace. But when I go online to buy it WTF is up with this 6 rib and 4 rib. Man Im confused. And also Im not really great with belts but how many belts are in a honda prelude? Might as well replace them since it's almost 90k. Ive got the timing belt done so im not worried.
