What would be the best type of thermostat to replace for my 08’ 5.7? The parts store guy saying 203 degrees one

The temperature sensor you are talking about is under the AC compressor in a 5.7L Hemi truck. He would be better off not trying, it's too much effort to attempt rigging anything to try that.How to bleed the air out of the cooling system on a 5.7 hemi

if you can't get that plug out, look on the right side of the water pump,
there is a sensor & wires.
That will also work as a bleeder
This would be best, trust the process.Best thing i ever used for burping the air out….

Yes ,that is the temp your engine will maintain +or- a few degrees. Also what goes into the heater core.How does the temp range work? Is it like a 203 will blow hotter air than a 193?
Had to replace stat from my 09 5.7Hemi several years back. Went to three different places, including dealership, the temp ranges were from 203-209. I was pulling a trailer then, so I decided to get a 195* No-Fault stat instead. Has been working great since, pretty sure it was replaced in 2014-15.Depends on what you're going for.
If you're keeping it stock, head to your local dealership and get a stock OEM replacement.
If you're looking for better, I've seen many on this forum discuss 190 and 180 t-stat replacements.
For me, I'll be going to a 190 this coming summer when I get tuned and do fan adjustments.
Regardless of what you select as a temp range, ensure you bleed the air properly.
I used to have a 6.1 and did a 190 t-stat upgrade, and bleeding the air was a ******.... took a couple of go's to get it right so my temp didn't spike.
Once it was dialed in, it was smooth sailing!
On an 08, more likely your heater core is partially blocked or the blend door isn't moving all the way. If you engine is running 200 F you should have lots of heat. They need to be flushed every 4 or 5 years to keep them working good.Is that why my 08 Ram has normal engine temp but the heater will only blow lukewarm air?
What we did on the fill of coolant. We let it run pour coolant in slowly. Put radiator cap on loosely turned it off let it sit overnight Poured more coolant in next day Should be goodWhat would be the best type of thermostat to replace for my 08’ 5.7? The parts store guy saying 203 degrees one
