Diagnosing coolant leak, 1991 3FE

[sysmod]

Hi, I have an intermittent coolant leak that I’m trying to diagnose. I’ve attached a picture of where I definitely see coolant occasionally dripping from—what gasket would I be looking at replacing?

There’s a separate leak higher up on the drivers side that I suspect is the water pump—I’ll save that headache for later.

That is a coolant cross pipe, shouldn't have coolant dripping from it, most likely your water pump or thermostat housing above or hose connection.

That crossover coolant pipe feeds the oil cooler and there are soft lines on either end. If they're 34 years old, you might want to consider replacing them.
Those belts don't look great either.

just replaced the alternator/smog pump vbelt about 2,000 miles ago. Kinda ingored the A/C belt because Im out of refrigerant and never converted the attachment. I should be getting that second alternator belt replaced soon.

Thank you for the reply! I suspected water pump, i guess ill just keep topping up the coolant until i deal with that headache. its difficult to get a good view at the houses underneath everything there but ill give it another look.
