Should I replace any other parts while changing timing chain? I've heard water pump, idle sensors & ect. What is best for my car? Thanks

I would replace the water pump, the 4 chain guides and the timing chain tensioner.I suggest these because the water pump on these leak all the time, the chain guides wear real bad and break, causeing noise and rattling. And last the chain tensioner, this runs off oil pressure to keep the chain tight but after alot of miles they get sludge in them from burnt oil and don't do there job anymore.I've done 100's of these you do not want to do this job twice, also I would go with OEM parts, they last and fit better.
