UDPs on a V6

Hey everyone, I am new to the site and have a question. I have seen UDPs on a lot of different mustangs. Most of which from what I have seen are not "typical" daily drivers and are more like weekend cruisers. I have a 03 V6 that I am in the process of doing a few bolt-ons to for now (true dual exhaust, CAI and maybe the UDP). (I know it is not a V8 and yes I had an old 5.0 but now I have my own issurance instead of on my parents the rate went through the roof). I know that the UDP kit for my car is just the pulley and balancer. Not the water pump, alt pulley or the p/s pump pulley. What I am concerned about more than anything is that the winters are somewhat brutal around here and the summers are just that "summer - extreme heat and humidity". Will it effect anything using these like overheating and or failures of other systems.

Just want to be sure before purchase and or install.

Thanks.
