I'm going to replace the breather box on my O2' S60 this weekend. Does anyone know the proper torque sequence and torque specifications for the intake manifold bolts? Any other advice or tutorials would be most appreciated. Thanks.

 

I do not use the torque specs. I use a 1/4 inch ratchet with a long extension. I always start from the outside working in from side to side.

 

Tech, thanks for the reply. The project was successful! (only one extra trip to the auto parts store for a lost fuel injector o-ring). The lower port on the breather was about 90% blocked. The upper, larger, port was about 60% blocked. Huge improvement in start-up, idle, and performance. Also saved a few hundred $$$ by doing it myself. Thanks for all the info in your previous posts. Knowing that there is help out there gives the occassional mechanic the confidence to tackle something like this. Next up - leaking power steering pump! Thanks.

 

Glad all went well for you!

 

this is pgu44...would you happen to know where to find torque specs for 2013 xc60 B6324S4 engine? Specifically thermostat, alternator mount bolts, water pump and the plastic intake manifold?
thank you
