Are ceramic pads and slotted rotors worth the extra money? I need to replace t-stat in my 2000 Volvo S70 GLT SE non-turbo, what temperature rating do i want for the new t-stat? Does this car have a PCV valve?

Rotors and Brakes yes, Timing belt No, the 99' has the Variable Speed Timing that changes the exhaust cam timing.

There are a few ways, it could be burning oil or making noise or not building pressure,

What problem are you having that makes you think turbo is bad?

this trans is well known for valve body issues

The bad news is the only part that is connected to all of these is the ECM or computer.

check head gasket and also check inlet manifold for cracks or inlet gasket

I believe the PO456,PO442 are evap conserns The PO301 is a miss fire on cylinder #1

You must drain the tank remove from the car flush it out with pump and screen out of it you will need
a list or car jack and several stands change the screen and fuel filter also . Good luck

could be a bad outer tie rod end or lower ball joint on the front suspension, to check jack up wheel (suspension supported) grasp tire and move back and forth, if you feel loosness you have a worn component. if there is no looseness then you have either an bad wheel bearing (excessive runnout) or defective rotors

did you replace All discs front and rear? if not , replace the ones that you previously didnt
