Timing belt change for 2000 4 cylinder Toyota 4Runner?

My recently purchased 2000 4 cylinder (2.7 liter) 4Runner apparently uses a timing chain rather than a timing belt. The vehicle has 87K miles. Does the chain need to be changed? If so, at what frequency? I have gotten conflicting messages in researching this subject.

Thanks in advance.Timing belt change for 2000 4 cylinder Toyota 4Runner?Don't mess with it. The chain has a tensioner that keeps the slack out. I changed mine out at 200,000 when I had to pull the head and figured it needed it. Maybe it did, maybe not.Timing belt change for 2000 4 cylinder Toyota 4Runner?no. Unless it has excessive stretch
