In the never ending quest to make my Ranger's 2.5 even more bullet proof, I tend to keep up on the maintenance of anything that needs done, when the truck needs it.

I'm getting ready to have my mechanic replace my radiator core support as my old one has rusted to bits. He noticed the serpentine belt was cracking after my upper radiator hose came a tad bit loose and leaked on it.

What are some other things I should consider replacing during the serpentine belt replacement?

Timing belt, water pump. radiator and upper and lower hoses have all been replaced within the past year or less.
