Default intercooler fluid change?

hi guys,

k, so i'm pretty religious on changing fluids and while my car only has 29k miles, it's a 2020, so today i had the transmission drained and filled, as well as the differential, and brake fluid, spark plugs, and air filter changed. oil changes are every six months as i never reach the 5k milestone before then.

most importantly right now, should i have the intercooler fluid changed?

are there any other big wear items that i need to give attention to? serpentine belt? visual inspection was okay, but i don't know the lifespan given that the car is five years old at this point. regular coolant/antifreeze? what about the fuel filter? do i just use fuel cleaning additives like chevron's techron concentrate to maintain the fueling system?

am i missing anything? this car needs to last for some time because my previous IS was totaled -- so sad -- and the insurance was awful with the payout.

thank you!

Guessing your car is a 4 cylinder turbo, intercooler has fluid ? Blow by oil ?
Clean any oil out of the intercooler and charge pipe. If you haven’t yet, spray the maf sensor clean and clean the throttle body. Another thing I like replacing on engines is the pcv but your engine still has low miles. Cabin air filter every year, and always use good premium fuel.

yeah, it's the inline turbo four. the turbocharger itself has a coolant reservoir that isn't fed by the main coolant system.

thanks for mentioning cleaning the others. i'll look for youtube videos on how to clean the intercooler and charge pipe. i had forgotten about the maf sensor and throttle body.

thanks!
