XKR 2001, 19,000 miles, ORIGINAL CHAIN ​​TENSIONER. When will I have to change them. LOW MILEAGE

 

Short answer is as soon as possible. With your mileage you probably have some time, but keep in mind the plastic is over 12 years old. You just never know. Some forum members are changing as quickly as 35k-40K miles. My 2001 just got changed at 100k (they were cracked).

A few hundred bucks if you replace them yourself vs. a brand new engine? So how lucky do you feel?

 

Change them now.
They are just a time bomb in your engine, how will you feel if you procrastinate and they let go?

 

Thank you, i will be, the time 12 years ahhhhh, ok,
