100k+ Maintenance

Hey Guys, Currently I have 132,000+ Miles on my 2009 Cobalt Trying to maximize the life of the vehicle, I have seen vehicles, both GM and others...with 300k+ and taking owners words for it...Factory Powertrain still intact and running fine...

I bought this car USED with 36,000 miles on it and have had no problems so far* but assume that no major upkeep was done except fluids and tires in its previous life as a rental vehicle.
I'm probably gonna leave out some detail sure to make me look like an idiot so bear with me...Leaving Stuff like Tires, Brakes, Rotors, Wiperblades and Gas off the list not necessarily worried about accessories.

I change my oil regularly myself, every 15k
Spark Plugs were changed at 100k
Last Transmission Service was at 120k
last Coolant change was around 100k
K&N Drop In Cleaned or at least checked every 25k
Regular Fuel Treatments / TB Cleaning
to my knowledge serpentine belt has never been replaced (almost 100k with me)
Fuel Filter was last changed at 50k

What sort of things on the front end might need work or inspection? There is no power steering pump as I learned when the fuse blew...lmao...

Again if I left out something huge I probably just forgot to list it (I hope) but I want to make sure I keep everything in good shape. Is there a "certain death" mileage on cobalts?
*(transmission was rebuilt at 120k but had been acting up as long as I had it)

suspension components along with brakes. should replace the timing chain too.

See I knew I would leave something out...Had suspension done...front and rear shocks/struts replaced...brakes have been done front and rear.... comin up again soon

Timing Chain?? I didn't know....not sounding like a DIY Project for me tho...typical cost?

well.... timing set if you buy online will be like 100 bucks or so... i'll tell you it's going to be a pain in the ass if you do it yourself. you should buy the haynes manual. like 25 bucks at any parts store

Hmm I just watched a video of changing the timing chains on a cavalier....I think I might need to pass on the DIY here haha....what would a reasonable shop price be? and Yea I do need to get one of those...been meaning too...just never happens

Hey by the way....minor annoyance...but still not quite right....when I use my turn signals sometimes the high beams come on...and quite often the lights don't go off until you move it up or down after removing key does it sound like the Headlight Switch might need replacing ?

if you replaced the whole assembly it could be alright. but that's something that would be situationally dependent for the fact that it could either be a bad wire or a switch
