Well first off where are you getting your numbers? You really need a scan tool for accurate data, just eyeballing the gauge can't really tell you 200 vs 210.

Were you able to ascertain where said puddle of coolant came from? If the rad cap released due to overheating it first goes into the plastic reservoir. If it boils over too much then, yeah, it would, well...overflow the overflow. But a puddle could come from lots of places....radiator side tanks, heater hoses, weeping water pump, leaky timing cover (the latter is almost surely seeping at least a bit if you're over 150k)...and more.

 

It's the water pump, gotta replace it today

 

You really, really want to do the timing cover gasket at the same time. The amount of extra work is negligible. And once the cover is off you're staring at the timing set so there's no better time for new chain and gears. Most guys here like the double roller set and it's under $30 at RockAuto (I have no idea if a NAPA could get it or might stock it)

It wasn't the water pump, it was a coolant hose I forgot to put clamps back on smh. Anyways it's still running a little hot, maybe 220ish. Could it be the failsafe thermostat making it run a little hotter? I also replaced the coolant temp sensor and can't really get a good connection on it, could it be that?

 

Yes to both. Do you have a laser temperature gun? If so, you can check the temperature at the thermostat housing and the coolant temperature sensor with it. If not, you can pick up one here - https://www.harborfreight.com/121-in...ter-63985.html
