Belt change, rear windshield wiper

[SIC102]

Hi,

I have a 4.0 2005 Explorer, 80,000 miles.

Had the oil changed at some cheap oil place and they told me the timing belt has some small cracks and needs to be replaced. I am assuming this is the serpentine belt as I thought the engine had a timing chain.....

....anyways - anything else that should be done at the same time as replacing the belt?

Also - the rear windshield wiper and sprayer have packed in - the fuses are ok but the high brake light and other electrics on the tailgate seem ok - any thoughts before I go spend $$$ to fix?

Thanks,
Steven

When the belt is off, spin the idler and tensioner pullys to see if the spin freely and without any noises.
