Changing Thermostat On 2006 1.6Lx

[ToneDeaf]

I think that it's time to change the thermostat on my Mk2 1.6LX .

In the current cold weather the engine is slow to warm and the temp guage quickly drops when idling or when the fan is used to heat the interior. The heater is also luke warm. The engine fan is not operating, therefore I suspect that the thermostat is stuck open.

Can I enquire whether the distributor/ignition module is actually mounted on the thermostat housing and therefore should be removed to allow easier removal?

Thanks
