Hello, I'm new to cars and repair, etc. I changed the serpentine belt myself but hadn't noticed these grooves until now. Are they normal? Did I buy a counterfeit belt? Did I put it on correctly? I haven't driven my car far yet - just idled it for 10 minutes. No lights are coming on. The car seems like it's operating fine.

Thanks
Meghan

This accord was in a front collision
it drives, it has 168k, new chain put in last year, new alternator, starter, battery. Selling complete engine and trans or whole car.

Title says it all, I have a 2011 accord 2.4 that is being completely stripped down, and anyone needs something just let me know, im in bismarck nd, but im not unfamiliar with shipping, I have some of the car already on there.

#5 cylinder is missing. I have changed the plug, ignition coil and the fuel injector. Ive had issues before but a plug or coil always seemed to fix it. I used the blue devil head gasket sealer. It seems thay this can clog up parts of the system. and now I cant figure out the issue. Any ideas where may be clogged?
