Hello –

Well the manual doesn’t show your information. That usually means they consider that basic enough to be performed by looking at it.

I will be more than happy to assist you if you can either take a several pics of the front part so I can see the belt routing or you can describe it.

From what you say…….you have 2 belts? One that goes to the crankshaft, alternator and power steering…..with no other pulleys in-between?

Then an inner belt that goes to the crankshaft, water pump, AC? Is this correct or am I missing something?

Do you have general auto mechanical knowledge?
