QR25DE Service Life Questions
Hey folks -
I’ve got a question about the QR25DE engine in my 2009 Altima 2.5S. I’ve read that the service life of this motor is 120,000 miles. I assume this is how long the motor itself is expected to last before allegedly needing replacing.
I bought my 2009 Nissan Altima 2.5S with 82,000 miles in 2012. It now has 130,000 miles and I haven’t had to replace any parts other than brakes. I’ve kept up with regular oil changes and transmission fluid changes.
However, I know it needs several parts and I intend to do the work myself (most of it). It needs front struts, rear shocks, a timing chain (based on how its lurching and stuttering while accelling from a stop), rear rotors and pads, differential servicing, and possibly a tie rod or bushing or 2 (I have to investigate), a coolant flush, and I believe the idle tensioner needs replacing. I’m hoping it doesn’t need tranny work.
And just for good measure I was thinking of replacing the alternator, serpentine belt, spark plugs because I’m sure they’re all within their failure/need replacing range.
HOWEVER, before I spend about $2,000 in parts - I wanted to ask the advice and opinion of the fine people on this forum: Is my QR25DE engine with 130,000 miles on it worth putting $2,000 worth of new parts and elbow grease if the service life of the engine is 120,000?
Would I be better off selling it to a private party and investing in a tuner car that has a better history of longevity? In terms of motor/transmission. I would also like a vehicle that has upgrade potential, unlike the QR25DE.
My thanks in advance for your thoughts.
