Buying a civic 1994 vti as first car

[kitkat]

We dont know its waterpump

didnt you ask the dealer what they think is the water coming from?

I did, and they said its probably just some leftover coolant when they over fill.

its probably leaky radiator or faulty thermostat cap
if your water pump fails, it overheats

I took it for a spin around 10-15 mins to check any oil leaking but it was fine except that coolant. In that case, are leaky radiator or faulty thermostat cap easy to fix for this model? They said they going to fix it when I come back but Im not that certain.
