recall of Electronic Stability Control

I took my 2012 Tacoma in for a recall - the vehicle is in great shape for 130,000 maintenance is up to date. The dealership requested the following that I can agree with (not listed) and others I'm not sure of; Perform power steering system fluid exchange service, replace serpentine belt, replace main circuit coolant, clean throttle body, clean fuel injectors. Any replies would help. thanks

 

The pink antifreeze is good for 100k.
The power steering fluid flush is easy; less than an hour to do yourself.
Does the serpentine belt have cracks and is it fraying? If so, replace it.

 

Only thing I would consider not DIY there would be fuel injector cleaning and I'm not sure a dealership is the right place to have that done anyway.

 

Fuel injector cleaning is a joke. They just pour some crap in the tank which you can do it yourself.

I use Techron fuel system cleaner. every few tanks of gas for a few bucks. Much cheaper than the dealer and just as effective.
