Can someone help me diagnose this noise? Watch video towards end.

It sounds like the lifters, which is normal

Watch by 00:41. The whole engine sound ok except by the front area by radiator inlet hose. Oil was not low, temp was <220F. I thought it could be a belt tensioner or something but it doesn't make noise all the time. No check engine light

Replace your belt tensioner and idler pullies. Mine were bad at 70k miles. Put a new belt on it why you are at it.

Car has 36k on it.

Pull the serpentine belt and spin all the pulley's by themselves. You will find the bad one. I had a similar noise for 15k and never figured it out because it was intermittent. Pulled the motor for the upgrade and boom. Easy to spot.
