Time to replace the pump.

When coolant comes out of that hole you know the pump is shot.

I believe that's the "weep hole"... designed to leak when the pump starts to fail.

Water pumps are far more simple and less expensive to replace than either fuel pump on these cars. Might as well do a complete coolant flush before you do with a new thermostat and hoses. A Gates WP on RockAuto is $20. All said and done with new coolant, you could do it all for around $60. If you feel like making a scenic drive down to the Valley, I can help you do it all.

Do NOT put a cheap auto parts store one on there. My oreilly $35 lifetime warranty pumps failed three times in a row, quickly. My Hepu is going strong. Be prepared for a rusty coolant pipe which may have to be replaced.

BS, a main fuel pump takes like 20 minutes and you don’t have to drain all the coolant. Lol

I know its fairly easy, I already have the car mostly apart to do it since I had an oil leak to fix coming from the oil cooler feeds off the filter base plate

+1 In spite of the extra cost, I used a made in the U.K. Volvo pump on my '88 244. In a year the hub separated from the shaft. On went a Hepu with Volvo gaskets. Three years later all is well.

Napa water pump did 3-4 years and then leaked through the same hole.
