Phew. Got the car's coolant system put back together and the tests were nice and successful. It even fixed the bouncy idle issue that had been a persistent bother for most of the time i've had the car (was rare at first and pretty much guaranteed for the latter half) Turns out that issue was simply caused by the slow drop of coolant level in the system that apparently nobody on the internet had ever figured out according to my numerous searches. I kinda knew the part where the bouncy issue was originating from, and had even done full cleanup and rebuild on the thing. A cold start idle assist valve thingy that works by having a thermally expanding glob inside it hooked to the coolant system that should disengage once the coolant has warmed enough to make that blob swell. The reason the coolant level had been showing up as "just fine" on the outside while fucking things up for that part in particular was because the part of the thing connected to the coolant loop with couple skinny little tubes was basically the tallest pont of the entire coolant system and would naturally end up sneakily drying out first while the rest of the engine still has plenty of juice to go around. Got the biggest suspicion only after i had drained the system and noticed the amount of liquid coming out was way less than i was expecting. Like less than half of its supposed capacity. God it feels sweet to have finally resolved that annoying idle bounce issue that had definitely made me look silly impatient and rude at crosswalks and traffic lights for years making it sound like i was repeatedly stomping the gas pedal every other second nonstop :v
