Snoop's Take

The HEVLE Car Thermostat is a high-performance automotive replacement engine thermostat designed to regulate engine temperature and prevent overheating. It is compatible with various Honda and Acura models, ensuring efficient engine operation by controlling coolant flow accurately. Consumer feedback indicates mixed sentiments regarding the thermostat's performance and compatibility. Some users have reported issues such as, "it was released maybe two weeks ago according to Amazon, and according to Amazon, JS doesn't have metadata for it yet," suggesting integration challenges. Additionally, there are concerns about potential negative impacts on fuel economy, with comments like, "the only way running a colder thermostat would cause using more fuel is because the motor is not getting to a high enough operating temp for the ECU to switch from open to closed loop." Given the feedback, the HEVLE Car Thermostat may not be the best choice for all users, particularly those with certain vehicle models or specific performance needs. Caution is advised for prospective buyers to ensure compatibility and suitability for their car's requirements.

Insightful Chatter

It has a software glitch that randomly turns the fan to ON… it REALLY runs your bill up not to mention wear on the fan.

Software glitch causing fan to run continuously
It has a software glitch that randomly turns the fan to ON… it REALLY runs your bill up not to mention wear on the fan.
Incompatibility with certain vehicle models
Trouble is, it was released maybe two weeks ago according to Amazon, and according to Amazon, JS doesn't have metadata for it yet so getting it integrated may be a pain.
I just want to check if the auto repair experts here ever installed such thermostat, and how the vehicle performs after the installation.
Using this thermostat is going to keep your vehicle in open loop longer, and definitely hurt performance and fuel economy.
You need to run the stock thermostat. You going to be right below the temp you need.
Incompatibility with certain vehicles
Different temperature thermostats? Hey I'm up in canada running a BEW diesel, I noticed that I can get different temperature thermostats, 160*F, 180*F, and O.E.195*F.
This. I had a 160F thermostat in my Jeep to combat overheating but it made the heater basically useless and it cuts into your mileage.
Potential negative impact on performance and fuel economy
The only way running a colder thermstat would cause using more fuel is because the motor is not getting to a high enough operating temp for the ECU to switch from open to closed loop.
I had a thermostat that wasn’t closing all the way and it made my fuel efficiency drop.

Discussion on compatibility issues with various vehicles
Best smart thermostat for carrier infinity system? I don’t want anything crazy.
Yeah, you would lose a lot of the Infinity system multi-stage features.
If you are getting a carrier infinity system, use the carrier infinity thermostat.

Ecobee is really great.

Cautionary Callouts

Know the pitfalls before they catch you off guard.
Discussion on the effects of lower temperature thermostats
A lower temp thermostat won't make your over-heating car over heat less.
It can cool more efficiently and prevent unnecessary fuel dumping.
It would be helpful for a lot of comments in this thread to be referenced against, or having an understanding of open loop and closed loop conditions.
Once you understand that the engine is on a loop flowing by a T with the thermostat you resolve the conflict.
Discussion on different temperature thermostats and their effects
The thermostat opens up the system to circulate once it hits its temperature. The oe 195f is going to keep coolant in the engine until it reaches 195f before it starts circulating.
Discussion on effects of lower temperature thermostats
Running a lower temperature will give your engine clearances that it wasn't designed for, so yes you can get more blow-by from the rings, or whatever.
Discussion about temperature gauges and their behavior
Temp gauges on these are slow. They only show a major change.
