hey guys, reached 120k on my xb and i've never had any of the belts replaced. never had any problems but want to do preventative maint. which belts do i need to replace?

 

serpentine and timing belt

 

You only need to replace the serpentine belt. Your xB doesn't have a timing belt, it uses a timing chain.

 

off topic but are the tc's chain too, or belt?

 

tC's are chain also.

 

How much do they charge to replace the serpentine belt usually?

 

i got mine done for 50bux including the belts,tax,and work, but its much cheaper to do your self if your up to it, just be careful for the camshaft position actuator thing! the first time i had to replace mine i DIY'd and busted it! turned a $15 replacement to a $120 job.

 

there is two belts on the xb. one for the a/c compressor, waterpump and alternator. one for the p/s.

 

Which belt does a lightweight pulley attach to?

I'm not sure about some of the internals of the engine, just wondering if it would be easier to upgrade since the belts are being removed already.

 

depends? you can get a lightweight pulley for almost every application, you can get underdrive pulley sets, just the crank pulley, or alternator, it could be either belt depending. i think we need a lil more specifics cuz theres 5 different pulleys.
but if this is your DD id say leave them be if there not broken/bent/worn. SOME aftermarket pulleys can cause unfavorable side effects, like not enough power to the alternator or overly stiff steering. the only real up to having lightweight or underdrive pulleys is reducing drag and moment inertia, the HP gain is almost negligible in our cars, maybe 1-3HP max.

 

thanks guys!

 

Yes, The '06 xB has 2 belts as stated above. All internal is chain. Just got back from dealer here in AZ and they wanted $175.00 to do belts (2). Got decent Dayco belts at Pep Boys for $35.00 and will install myself as there seems to be a bit of room in there. Any "sticky's" or step-by-step on this, or is that even needed?
As always....Thanks to all!!!

I bought the same dayco belts, same part #'s as well, but mine say poly rib not poly cog like in the example from clubxb? how can you have two different belts with the same part number but are different belts!!!!
