Here is part two on the 2015 Nissan Quest! We came out to do what should have been a simple serpentine belt and tensioner swap, unfortunately it turned into a little more than that. Our previous video showed the old tensioner pulley had failed and caused the belt to snap on this vehicle.
Now, right as we went to back out the tensioner bolts, we felt a lot of unusual resistance. Heat and penetrating oil were our first go-to, but it didn't help. Both bolts ended up snapping off, leaving us with two bolts needing to be extracted.
With such a tight fit, we decided to remove the plate/timing chain cover that the tensioner mounts to, which made the extraction much easier. From there, we clamped it in a vise, applied heat, and worked the broken bolts back and forth with vise grips until they eventually came free. Each surface was properly cleaned and fresh silicone was applied to the cover plate on reassembly.
This is normally a straightforward job, but living in the Rust Belt, you never know what surprise is waiting. Either way, the job got done right and the customer left happy!
Whatever surprises come our way, we'll be ready to handle them and get it done right the first time.
