I use this forum a lot for advice and I am completely stumped on what could be causing this issue. I've been driving a 1993 Jeep Cherokee for a little over a year, replaced water pump, upper and lower hoses, heater hoses, heater control valve. all of These have been replaced relatively recent but all of a sudden I have been leaking water from one of the heater hoses on the heater control valve, leaking water at the upper radiator hose to t-stat, and finally this morning i busted a leak on the bottom corner of the radiator. Is there any reason why all these leaks would be popping up all of a sudden?

If you haven't run it hot, then I would think the radiator is due for replacement.

Check the firmness of all the hose clamps. They might need a little tweak here and there.

The initial leaks were coming from the hoses and i tightened all the clamps by a half turn, that sealed up all the leaks around the hose and then the radiator started leaking this morning. never goes past 220 degrees before the e-fan cuts on and cools it off. Sits at 210 during commute. I'm wondering if anything would cause a sudden increase in pressure in the system

Well, a blown head gasket, cracked head or block comes to mind.

I wouldn't jump that far yet without a diagnosis, though.

How would I go about diagnosing any of those? I checked for oil in the coolant and found none, didn't find coolant in the oil either. Also, I've seen nothing leaking from the block itself

Get a kit to check for combustion gasses in the coolant.

If something is blown into the water jacket, oil and coolant don't necessarily mix. But it will pressurize the system.
