no if the pump is leaking it is bad and nedds replacing
thermostat gasket probably leaking. replace thermostat and gasket making sure that thermostat housing is flat.
only if the gasket under thermostat is leaking and may-be it's the hose clamp on the hose that is leaking
Check your coolant levels, and check your thermostat - it may need replacing. Also check your heater hoses to ensure they're not leaking.

Failed seal. Replace it.
Radiator may be plugged or restricted and need boiling out or replacing
The housing retainer bolts are loose or the gasket has deteriorated. If replacing the gasket, use pliable gasket sealant to improve the seal. it could also be the water pump went bad and leaking water down beside the thermostat. the thermostat is part of the water

Running it while leaking can cause it to overheat repeatedly, which can cause thermostat damage , along with other problems.

Thermostat and radiator
"transmission fluid leaking from fitting below radiator cap after replacing radiator on 99 surburban
Hello. Mine had the same problem after replacing the waterpump. The thermostat is fitted in the pump manifold, with some shims. I found it strange that there was no hole in the thermostat valve, so i drilled one myself (2-2.5 mm). This helps air to escape and starts a small flow, allows the hot coolant to reach the thermostat. This prevents opening al at once when the coolant is already heated in the engine block. On top of the head there's a coolant manifold with a bolt in it. This is where you have to bleed the air, there might be air in the system that can't get out. During the bleeding, the heater must be set at highest temperature. The heater radiator flows, and if there are bubbles in it they will get out. The shims in the pump are important too. If the thermostat is not in the right position it won't work properly. If the air keeps coming back in the system, it might be a leaking head gasket. In my case something was wrong with the new pump and new thermostat, after the drilling and mounting differently with the shims my problem was solved. If air is not the problem try replacing the thermostat, it's fairly easy and cheap.
Defective seals, and it needs replacing.
The fix is replacing the leaking part.
looks like a sensor or thermostat going into engine block
Remove the housing and replace the gasket.
A leaking water pump means the pump needs replacing or the gasket is leaking. Either way the pump must be removed. Now if the hoses going to the pump are leaking, they either need tightening or replacing. So it depends on exactly where the leak is.
Your thermostat is sticking in the closed position,it is usually located where the top radiator hose connects to the engine. Very inexpensive item
You will be better off replacing it that trying to repair it.
Whatever seal the fluid is coming out.
The housing gasket may be bad. Replace the gasket.
