Do I use 10w 30 oil in my Volvo 2002 S60 T5 - 2002 Volvo S60

If it calls for synthetic, that's what it needs. Period

it a round cap with 2 bolt should be on the end of the camshaft

this may have a starter relay that would power the fuel pump after started also this will be a fused system check your fuses are their any codes sometimes cars are equipped with a fail safe system that will disrupt the running if their is a fluid issue like low oil or coolant or even bad oil pressure

it needs a new siren module

The factory calls for 5W-30, but other considerations would be mileage and usage.

you have a cracked head or bad head gasket.

go tt www.volvocars.com select your region (ie United States). Go to sales&service and click on volvo owners info. you will have to register but all that is required is an email address. Put in your information about year and model car, you can click owners information and should be able to download a free copy of your owners manual. I had to do the same thing for my s60. I hope this information is helpful to you.

This has to do with the anti-lock brake system. It will be fine without it, but if you want it fixed get it done at a dealer not a shop. It will cost a lot more but the repairs will be done right and will last longer.

Castrol GTX 10w-30 or 5w-30 should work fine. Use 10w-30 if your in a state that gets temperatures below 35 in the winter.

Check the fuse and the wirings.
