Thermostat problems on the horizon
Good day
In the past week I have noticed on two occasions my temperature drop from about 90 to just over 75/80 then creep back up in about 20 seconds
The first time was on the motorway, coming out of traffic that was crawling in parts, got up to 70 mph and the car seemed to drop to just above 80 then find its way back. I travelled 40 miles back in the evening and it didn't happen again. Today was I crawling through traffic and noticed that once I accelerated up to 40mph the temp gauge did the same.
Now the coolant is filled up to the max and I have a lot of driving coming up so want to know if there are problems ahead for me. The heaters are pumping out the heat, and the car takes a few minutes to get up to temperature of a morning
Let me know your thoughts

Possibly, but if anything the thermostat is opening at too low a temperature so at least you're not going to overheat.
I changed the thermostat on mine last year as it was running a bit low. I once noticed that if I lifted off on the motorway going quite quick, the temp would drop dramatically due so much air going through the rad, before the thermostat caught up after a few seconds.

My only concern is that I have about 2500 miles of driving in the next 60 days so fingers crossed. Whats the labour cost for something like this, 2 hours?

Yeah, depends on the car.
I did mine myself which did actually take about 2 hours but that was with never having done one before and access was difficult with it being a 2 litre in a fiesta.

New temperature sensor on it today, showing about 75 degrees as the engine temperature and it takes a while to get there. It is going to garage tomorrow for further diagnostics, talk of it being the thermostat but the heaters are still absolutely roasting.
Any thoughts?
