Vehicle: Ford Ka 1998 1.3L - Endura Engine
- start engine
- wait a few minutes (10-ish)
- coolant starts pouring out from where two hoses like this one interconnect (I'm assuming it's a coolant hose)
After I stop the engine:
- in a few minutes the leak stops
- you can hear some faint hissing under the bonnet
- you can also hear pops (like a hot exhaust cooling)
This does not seem to happen when the vehicle is moving, only when stationary for a while with the engine running.
Things I've tried:
- burping the car
- removing thermostat
- since it doesn't have a temp gauge, I attached an OBD adapter -- coolant started leaking at 81°C -- kind of early to be an engine overheating issue?
Other (maybe relevant notes):
- cabin fans give warm air on both hot/cold setting
the hose that goes to the overflow tank is really hot
the hose from the thermostat is also very hot, and I think it's bulging
I've been to a shop and they said it's probably the head gasket, but they can't say for sure.
Are there any other (cheaper) things I can check before committing?
The leak started at about 81°C:

The hoses that go into the coolant overflow tank are very hot
