So I've a pretty bad coolant leak at the moment. Usually after commuting back and forth to work for two days (about 40 miles) I'll have to top up my coolant again if not sooner than that! and some mornings I'll come down and there is a pool of coolant under the car.
All the expansion tank is bowed it's not leaking. I know there was a leak in the thermostat housing, but I've just changed the gaskets and the leak is still happening from somewhere else.
It seems to be pooling at the bottom right (facing the car) of the gearbox sump. Here is a pic for reference - https://ibb.co/e0fzH6
Could this be from the water pump? Or where else should I be checking?
Thanks in advance!
