Temp guage from 4 bars to 3?

[Tbone289]

Thanks, that tell me between 3 and 4 is 20 degree difference. My concern is that for over 2 years I have not seen it vary from 4 bars. I have now seen it drop back to 3 bars several times. Could this be the thermostat acting up?

It sounds normal to me. Monitoring temperatures through OBD-II, in cold weather temperatures dropping in to the upper 170s isn't uncommon. It can take quite some time to reach a full warm-up where it stays around the normal 185-degree thermostat temperature (4 bars).

When the ice engine on my hybrid stops. I noticed the temperature drops pretty damn quick.
Personal preference.
As much as I love my hybrid.
If I lived anywhere above the 40th parallel North I would own an EcoBoost.

I'm above 42nd and the hybrid seems fine to me.

I guess that would be your personal preference.
I didn't say that there was anything wrong or that it wouldn't run.

The 2023 manual says hybrid has electric booster heaters.

Electric Booster Heater Operation
The electric booster heater ensures that the passenger compartment can be quickly warmed up when ambient temperatures are low.
It is a heater element made up of ceramic resistors that is mounted in the climate control housing.
It directly heats the airflow into the passenger compartment rapidly in the case of low ambient temperatures.
The current is switched via three electric booster heater relays located in the BJB / BCMC.
...
Electric booster heater operating parameters:
• Engine is running
• HVAC controls have been switched to the highest temperature setting
• Engine coolant temperature is below approximately 75°C (167°F)
• Ambient air temperature is below approximately 12°C (53.6°F)
• Sufficient generator capacity is available

The electric booster heater is deactivated when an engine coolant temperature of approximately 85°C (185°F) or an ambient air temperature of approximately 15°C (59°F) is exceeded.

Oh yeah, I understood. My other vehicle is a 2022 F150 and the interior doesn't warm up any faster than the Maverick in the winter. I just wouldn't want to discourage northern people from considering the hybrid.

Lots of short trips, a Hybrid is not ideal for cold climates. No harm. But no advantage either.

If you are mostly going on 30 minute trips or longer in the cold, Hybrid still has lots of advantages.

For lots of short trips an EV makes sense. No ICE likes not getting fully up to temp for a bit each cycle. It's 15 minutes to anywhere for me, and I start off on a 55-mph highway in front of my house on the way to town. I really have no negatives for the powertrain, keeping the cost and purpose in mind. I definitely have criticisms for Ford, but I think they did a good job on the 2.5 hybrid.

Agree.

I bought one of the first ever made. Call me an early adopter. Came back to buy a second, and third Ford Hybrid. My mom bought two. (Her's were both Fusions). Never any major trouble.
