If you are concerned about engine temp not being high enough , try a piece of cardboard in front of the radiator .
I did that once , on an older vehicle . Winter time & apparently the tstat stuck open . Little / no heat from the heater core . I was COLD , in the cab .
The cardboard helped me & the engine warm up .
Watch the temp gauge & remove some or all of the cardboard , when it is no longer needed .
God bless
