Spent 6 hours hunting a coolant leak on my '94 pickup that turned out to be a $4 o-ring
The thing that took way too long was chasing a mysterious coolant drip on my truck's water pump because every forum said it was the gasket, but after pulling everything apart twice it was just a dried-up o-ring on the bypass tube that took 20 seconds to swap once I found it.

Man, thats the worst kind of fix right there. I had a similar thing happen on my old Ford ranger where I swapped out the whole radiator and both hoses cause I was sure it was a cracked tank. Spent like two afternoons bleeding the system and swearing at it. Turned out it was just a loose hose clamp on the heater core line. A thirty cent clamp I already had in my toolbox. I felt like a total idiot but also kind of proud I finally found it you know? Its always the cheap little part that makes you want to punch a wall lol.

Used to be the opposite for me actually, always blamed the cheap stuff first and went on a wild goose chase replacing clamps and gaskets before I'd even check the big parts. Then my buddy's Cherokee overheated bad, I spent two days swapping out his water pump and thermostat housing because the temp gauge was all over the place. Got everything buttoned up, still overheated. Turns out the radiator had a hairline crack you could only see with a flashlight at night. Had to eat crow and buy him a whole new radiator. That one hurt my pride and my wallet. Now I start with the simple stuff but I stop assuming it's always the simple stuff.

Wipe down every dry o-ring before assembly, it's the only way to catch the sneaky ones.
