Technical 6 Major coolant leaks

[antonis132]

I was adding coolant every week on my Fiat Panda 1.2 169 on the last month. So, i had time and repair leaks, i found in the morning when the engine is cold. Leaks spotted on several points.

After leaks like this, I would be doing compression tests to rule out head gasket problems. Did you have any work done before it started leaking?

Water pump is annoying as you'll have to fit a new cam belt while replacing the pump. But if the head gasket has gone you'll be doing it anyway.

The radiator bottom hose is either the (so called) quick release (QD) connector or it needs a new hose clip. The one behind the coils is likely to be the thermostat housing but could also be a loose hose clip.

The heater hose air vent screw might need a washer. Just loosen the screw and wrap some plumber's PTFE tape around a few times to create a sealing washer. If the screw itself is damaged, you can replace with a standard M6 bolt and fibre or PTFE washer. Stainless is nice but not necessary. If the thread is stripped tap it out to M8.
